Hands on Review BrewZilla Gen4

I’ve brewed on several different all-in-one units. Like any brew system, they each have their own strengths and weaknesses. I did a hands-on review of the Robobrew when it first came out in late 2016. It has since changed its name to BrewZilla and is on the 4th generation of the brew unit. As you’d expect with repeated generations, they’ve been able to focus on fixing deficiencies in their previous models and also introduce new features.

The basic premise of an all-in-one brewing system is that your mash and boil kettle are in the

same vessel. So just like Brew In A Bag, after mashing, you pull the grains out and the wort stays behind to be boiled. They use electricity for heat, so they can be used outdoors where you can reach power or indoors where you have a venting system that can take care of all the steam you make during your boil.

BrewZilla Without Jacket

Stamped Volume Markings

Here are some basic stats on the Gen4 BrewZilla. It’s available in a 35-Liter form (for 5-6 gallon batches) with either a 110V setup, or 220V. There is also a larger 65-Liter that is only 220V (targeted to 10-12 gallon batches). The 35L unit holds 9.25 gallons, the mash basket can hold up to 23.5 lbs. of grain, and its electric heating elements can output up to 1500W of power (110V system) or 2400W of power (220V system). The 65L unit holds 17.1 gallons, the mash basket holds 41.5 lbs. of grain, and 3500W of heating power. All the Gen4 units have a pump bolted into the base. The pump can be used not only for wort recirculation during the mash, but also to pump beer through your wort chiller apparatus (should you choose to not use the immersion chiller coil included with the BrewZilla). The pump is more modular and accessible than previous Gen models. To protect the pump from clogging with hop debris during the boil or whirlpool, there is a filter screen (a perforated stainless disc that sits at the bottom of the unit) that sits at the bottom of the kettle. The small magnetic drive pump has a pump head rating of 1.5 – 2.1 m (4.9 – 6.9 ft) and a max flow rate of 11-12 L/min (2.9 – 3.2 gal/min).

Control Panel Notification During Mash Profile

One of the key upgraded features of the Gen4 BrewZilla is the controller. RAPT Is Kegland’s line of wireless connected brewing devices. The BrewZilla now has a RAPT controller so it adds a lot of features that can be monitored and controlled over Wi-Fi. This includes basic things like monitoring temperature from your laptop/cell phone, but also allows you to program complex mash programs online and then download to your BrewZilla. You can also adjust control parameters on the fly such as pump output duty cycle and heater output level. If you get the optional Bluetooth thermometer, you can stick the temperature probe into the middle of your grain bed, and then have the controller use that as its control signal in combination with the built-in temperature sensor that sits on the floor of the unit.

Bluetooth Temp Probe in Middle of Mash

Although All-in-One units are essentially BIAB, they use a stainless steel basket with holes in the bottom of it instead of a bag, and call it a “malt pipe”. These provide functional improvements over a nylon bag. The obvious one is they are way easier to clean. But they also allow you to ensure you get full flow through your grain bed by having holes only on the bottom. This means recirculating wort has no sneak paths out the side. The other benefit is malt pipes have simple brackets/feet welded onto the outside that allow you to lift your wet grains up and prop the malt pipe on the brew rig to drain or sparge. The BrewZilla has 2 sets of feet for this. One set is halfway up, allowing you to do the deadlift of grain & wort halfway and then let the liquid level drain down. Then when you lift it the full height, it’s not as heavy. It’s simple, but makes the process much better.

Welded-on Carry Handle (top) and Tip Handle (bottom)

There is a cool feature in the BrewZilla which normally only comes on much higher end systems, and that’s the central drain. With a concave bottom with a drain at the lowest point in the center, you don’t have to leave wort behind or goof around with tilting it to get the last drops of wort out at the end. This also enables the malt pipe to extend down lower and thus you can hold more grain (30% more than their Gen3). If you compared to other All-in-one units in the “5 gallon batch” size range, the 23.5 lbs. grain capacity is 30 – 50% more. This of course only matters if you’re trying to make high gravity brews. The drain in the floor is plumbed to the inlet of the pump below, and then you can direct pump output either to an external spigot for fast/easy transfer of wort out after brewing, or up the recirculation pipe for wort to get directed down on top of the mash.

Polished Bottom with Center Drain and Built-in Temp Sensor to Side

Bottom Side of Pump Filter Plate

To help with mash efficiency and mash temperature uniformity, they offer a Heat Exchanger Dish, which is just a stainless dish/plate that sits below your malt pipe and above the central drain. Without this dish in place, the flow of recirculating wort tends to go through the center of your grain bed, and straight out the drain. With the dish there, it directs the flow around the full circumference before it gets to the drain, which helps ensure a broader portion of the grist sees the flow.

Another helpful option is the neoprene insulation jacket. This helps keep mash temperatures more consistent by cutting down heat loss through the walls of the unit. The jacket on BrewZilla also smartly covers the recirculation pipe to minimize heat loss during wort recirculation. The overall mash temperature response with a multi-step mash was impressive, with more detail provided in the Hands On section, below.

Hands on Trials

First off, all of the different parts were well made with good quality manufacturing. As I’ve found with all Kegland gear, it’s of good quality- but nothing flashy. The one exception was probably the smooth and highly polished dished bottom. That was flashy. And being a previous owner of a 1st Gen Robobrew, I was very happy to see the camlock fitting on the recirculation pipe and see that Kegland was obviously tuned in to customer feedback on their products.

Mashing-in Sequence

Sparging

I brewed three different batches before writing this review. Two of them followed a simple single temperature mash, and the third one I exercised the RAPT Controller more with a multi-step mash profile, with lots of monitoring via my smartphone. I was impressed with the mash efficiency I achieved. There can be a misconception that BIAB = lower mash efficiency, but really, it’s “full volume mash = lower efficiency”. I had previously done experiments with an Anvil Foundry that showed a sparge step can get you mash efficiencies > 80%. Therefore, my batches in the BrewZilla were all done with a sparge step. I rested the malt pipe at the top while pouring heated sparge water through it with a 1-gallon pitcher. The perforated plate sitting on top of the grain bed made it super simple to sparge like this and get a good water distribution pattern. The perforated plate also allowed me to push down very easily and squeeze out remaining liquid in the grains. If you’re in the school of thought that squeezing the grains is bad for your beer, this isn’t relevant for you. For the rest of us, being able to easily squeeze that out without making a mess was awesome. And it meant when I picked up the basket of spent grain, I didn’t have a trail of sugary malt drippings to clean up after. My first batch achieved 77% mash efficiency, the second one 80%, and the third 81%.

Recirc Flow Rate After CFC

I experimented a bit with the Bluetooth RAPT wireless thermometer, but I didn’t properly understand it at first. I thought the concept was I could choose whether to use the built-in sensor at the bottom of the unit or the Bluetooth thermometer, but that wasn’t the case. When you add the Bluetooth thermometer, it will then control to that temperature, but it still uses the built-in sensor as part of your heating in a way that lets you fine tune how the system as a whole responds to temperature steps in your mash. After tinkering with it a bit, I realized it has some really powerful potential, but requires a deeper dive and some experimentation to back it up. So I’ll save that for a future write-up.

Bluetooth RAPT Thermometer

My typical brew system uses a 10-gallon kettle with a pump recirculating wort through a 240V RIMS with a 3500W heating element. With that set-up, I get about 3.1 degrees/minute temperature rise when doing multi-step mash profiles. I was therefore expecting this 120V/1500W system to be slow but was shocked to find similar performance that averaged around 2.5 degrees/minute. I attributed this capability to the neoprene jacket. On the plus side, that means you can do multi-step mashes even on only a 120V outlet and not take all day. But leaving the lid on as you heat to a boil is still a must. With the large opening in its domed top, it still can allow any volatized compounds to flow out.

BrewZilla Mashing by Itself in Basement

I found the RAPT software a bit non-intuitive and as such, had a learning curve to it. Luckily, I did a trial run just with water in it so I could get a feel for where various controls were located and how it worked. I definitely recommend this before you try to do any multi-step mash program, or live monitoring of things from the App. Way less stressful when it’s just water! After I got the hang of it, I was able to monitor my mash well and know what was going on as it chugged away in the basement and I worked at my day job one floor above. One key thing I learned was the in-flight plotting of mash temperature isn’t a continuously updating graph, you have to hit refresh in the App to get the updated data that it is recording and holding. I assume this is for computing efficiency and Wi-Fi bandwidth load management. It was perfectly fine once I figured out how it worked.

Screenshot of RAPT Controller Interface

The RAPT Controller allows you to program in multi-step mashes. But it’s a bit clunky as you figure it out. When you build the profile up using the App or Web interface, that profile sits on the RAPT server. My brain kept wanting to think I was programming the controller directly on the unit, but that’s not how it works. So after you program in the profile, you have to download it to the controller on your unit for it to work. You do all of this through the RAPT portal, and it only requires your BrewZilla to be powered on to let you download to it. This would be cool if you could just export something from Brewfather and then import it in RAPT, but you can’t. However, when you think about it, you probably don’t have that many different mash profiles, so it’s not really a big deal.

Malt Pipe

Draining Malt Pipe

One super cool feature of the mash profile programming is Kegland finally did what many have wanted these controllers to do for a long time. Rather than open loop programming a temperature and a time and guesstimating how long it will take for your mash to reach that temperature, you can tell it to not start counting down your mash step timer until it reaches the temperature. So if you want a 45-minute rest at 150F, you don’t have to think about how long it will take to get to 150F, it just heats up, and then starts the 45-minute timer when you hit 150F. I really liked this. You are also able to set up notifications at either the beginning or end of a particular mash step. I had it send an alert to my phone once it had reached mashout temperature and thus had 10 minutes left in my mash. That was cool, too. This isn’t quite as simple as it sounds, though. What I found was if the PID controller didn’t overshoot my target temp, I spent several minutes closing in on the target, but didn’t hit the temperature to start your countdown timer. So I’d end up with long mash times. I did some experiments with PID gains and the Bluetooth probe that got this working as I wanted, but I’ll detail that in a later write-up.

Rolling Boil at 75-percent Power

There wasn’t a boil timer interface, the controller was really just geared to controlling & monitoring mash temperatures. Not a big deal, as my Brewfather boil timer works great for this, so it isn’t a feature RAPT needs to spend time making. I could easily maintain a robust boil if I wanted to, but I like to keep it at just a good rolling circulation, so I dialed down the heating element power to 75% and maintained a constant churn of the wort and allowed boil-off of 0.4 – 0.5 gallons per hour. And the filter dish at the bottom of the kettle worked great to keep hop debris out of the pump, but not restrict flow. I had a thick cake of hop mush at the end when it was time to clean. Cleaning was fast and easy with parts light and easy to pull out, come apart, and rinse. And with the built-in pump, it was also easy to fill the unit up with cleaning solution at the end, circulate it through the unit & my Counter Flow Chiller to get everything clean.

Chilling Wort Using CFC and Built-in Pump

For wort cooling at the end of the boil, I used the built-in pump and circulated wort through my CFC. With the camlock fitting on the BrewZilla, I could easily hook up my typical ½” silicone tubing hoses. I was unsure if the pump would be up to the job, but it handled it easily. I could get a good volume flow rate with the recirc valve wide open on the BrewZilla and could easily restrict it when I wanted a slower flow.

A couple of pro tips to wrap things up. First, is to make sure you add your grains to the malt pipe BEFORE you lower it into the vessel. This ensures the weight of the grain keeps the bottom plate in place, so that as you lower it down, the water doesn’t push the bottom plate out of position and create a sneak path for whole grains to get through. Second is to make sure you have the plug fully seated in your brew unit. This might sound stupidly logical, but with a 6-foot power cord, you might end up pushing the limits of where you want the unit to sit vs. where the outlet is you’re plugged into. I had the cable become partially unseated and I wasn’t aware- until I went to remove the cord at the end of a long session of PID controller experiments. If the cord isn’t fully seated, you get less electrical contact on the pins and less contact means higher heat as electricity flows through it. I ended up damaging the cord and the receptacle from overheating.

Conclusions

The BrewZilla Gen4 delivered. The controller worked great, and I absolutely loved the step mash ability to start the mash step timer using actual mash temperatures. The RAPT interface wasn’t quite as slick as I would’ve liked but overall worked flawlessly, with no glitches. And I was definitely surprised how well a mere 120V/1500W system could handle mash steps and boil intensity. The well-thought-out little pieces of the malt pipe and various recirculation designs showed to me a system that was engineered with actual brewing hours spent on the unit, which is great. I feel with all of this, I won’t have compromises on my brew day using an all-in-one system versus my bigger 2-vessel system. And that says a lot.

Special thanks to Kegland for providing the unit used for evaluation in this review.

Hands on Review: Anvil Foundry Brewing System

Anvil Brewing Equipment Foundry

There are a lot of all-in-one electric brew rigs on the market. The entry to all-grain for most was through a converted cooler 3-vessel system. It was the cheapest way to get into all-grain, and why so many of us came that way. Precision control and/or electric heating convenience came at a premium that you would upgrade to later. Well, those are now relegated to “old timer stories”. At the all-grain entry level price point, you can now get an all-in-one electric unit from Anvil for the price you’d pay for an Igloo cooler kit with a burner and pot. So now those getting into all-grain can start with the precision of digital temperature control, and the weather-proof convenience of an electric heat source.

Comparing Anvil Foundry Versions

The Anvil Foundry comes in two sizes, a 10.5 gallon and a 6.5 gallon. They share most all of the same features, but the 10.5 is targeted at 4-5 gallon batches, and the 6.5 for 2.5 gallon batches. There’s also an accessory you can order for the 10.5 to insert in the mash basket and then go as low as 2 gallon batches. Both of these units come with the option to add on a recirculation kit, which provides a pump and some other hardware bits to allow you to recirculate wort during the mash. Every unit also has a simple switch you can change to run on 120V or 240V. However, the unit comes with a 3-prong 120V plug, so if you do opt for the 240V setting, you have to cut the plug off and attach the appropriate 240V plug type.

Save $90… BrewZilla Gen 4 on Sale at William’s Brewing + In Depth Hands on Review

Brewzilla 35 Liter Gen 4 110 volt

Brewzilla 35 Liter Gen 4 via William’s Brewing

More Info

From the product description, check product page for current description, price and availability:

The Brewzilla Gen 4 features a RAPT compatible controller, which means you can track, record, and monitor your beers online through the RAPT portal at https://app.rapt.io. It SHIPS FREE to lower 48.

• Recirculation Pump

• Mash & Boil, and Chill

• Mash up to 20 pounds

• Distilling Options

• Free Wort Chiller Tubing Connection Kit Included

• Runs on 110 volts, plugs in anywhere

New Detachable RAPT WIFI Controller

The RAPT portal has many features: you can see a record of your previous brews, remotely control the unit and turn it on to preheat from your phone, alter temperature settings from your phone, and more. Custom mash temperature profiles can be created and stored, alarms can be set if you want it to remind you when to add hop stages, or tell you when the strike water is heated and it is time to mash. All functions go through the RAPT controller; there are no longer toggle switches to control things like wattage and the pump.

New Concave Draining Base

The new base is dished towards the center so it drains all the wort. No need to tilt the unit to extract every drop of wort.

Larger Capacity Malt Pipe with Two Positions

The new high flow malt pipe is 20% larger than the old, meaning the 35 Liter Brewzilla can now mash up to 20 pounds of crushed malt per batch. This is great for high gravity beers, and enabled by the new concave base drain, which gave the designers more room for a malt pipe. The malt pipe also now has two positions, so you can lift it halfway up and twist for smaller batches, or lift it all the way like before for full batches. This is the latest version, with side perforations in addition to bottom of the basket perforations.

Easy Access Pump

The bottom cover has been reduced in size to only house the sensitive electrical components. This leave the pump easily accessible in case you need to clear a clog or replace a drain hose.

The Gen 4 Brewzilla with Pump from KegLand features a recirculation pump, as well as a false bottom and grain pipe to both protect the pump from clogging, and hold the crushed grain above the bottom for good wort circulation. The Unit holds 9 gallons, although we do not recommend boiling more than 6½ gallons (perfect for 5-6 gallon batches). The grain pipe (basket) holds up to 20 pounds of crushed malt, and a pipe with included silicone hose on top feeds the recirculated wort from the pump evenly on top of the grain bed. Runs on any GFCI protected 110 volt plug with at least 15 amps. Includes a free Chiller Tubing Connection Kit with 15’ of tubing. Dimensions: 12” by 12” by 25” with the grain pipe removed.

Upgrade KegLand DigiBoil to All In ONE w/Mash Upgrade Kit – on sale for… $49.99

Digiboil 35 Liter Mash Upgrade Kit

This grain pipe kit lets you mash with the 35 Liter Digiboil. It includes a octagon basket holding ring that pops into place on your unit, so the assembled malt pipe can be raised and twisted for sparging.

Note that the Digiboil was designed for boiling, and does not have the more complex electronic wiring of say a Mash & Boil or Digiboil, so when the malt pipe is in place, you will need to use the 500 watt element only to prevent grain from burning onto the element.

Includes malt pipe, bottom screen for malt pipe, false bottom (that goes below the malt pipe), and malt pipe lifting handle. All items are 304 grade stainless.

This fits the Gen 1 Digiboil with a stainless lid. It does not fit the Gen 2 with a glass lid, as the wire basket holder does not fit the Gen 2 boiler.

Father’s Day Deal… KegLand DigiBoil Electric Brew Kettle – on sale for… $154.99 at William’s Brewing

KegLand 35 Liter Digiboil (110 volts)

KegLand Digiboil from William’s Brewing


From the product description, check product page for current description, price and availability:

The KegLand Digiboil is an 8 gallon electric brew pot with precise digital control. Made of 304 stainless steel, it features 1500 watts of total power, selectable with both a 1000 watt and 500 watt switch. Perfect for brewing, distilling, sous vide cooking, and more. Keep in mind that although it has an 8 gallon capacity, we recommend you boil no more than 6.5 gallons, to allow head space to prevent damaging boil overs.

The digital display can be set to any temperature between 32° and 212° F, and hold that temperature to plus or minus 5 degrees. The valve features standard 1/2″ threads, so you can fit female NPT 1/2″ accessories such as cam lock fittings to the spigot for attaching chillers and other accessories. The rim features clamps, and standard Robobrew and Grainfather distilling lids will fit perfectly. 27″ tall, 12″ wide.

This unit draws a hefty 15 amps, and must be plugged into a dedicated GGCI outlet for safety. The unit should not be submersed in water.

The Digiboil does not come with a printed manual, but it is very simple. One of the first things you will notice is that it is set in Centigrade. To switch to Fahrenheit, with the unit on and both element switches off, press the plus and minus keys simultaneously for 5 seconds to switch it to Fahrenheit display mode. To set the temperature, turn it on with water in the boiler, and press either the plus or minus key until the set point starts moving, and release when your desired temperature set point has been reached.

When brewing with malt extract, you will need to get your water boiling, then shut off the heat momentarily while you stir the extract in to dissolve. This eliminates the extract from burning on the bottom, and prevents the thermostat protective circuit from throwing an error. As soon as the extract is dissolved, turn back on the heat and brew.

Hands on Review: BrewZilla Gen 4 + Limited Time DEAL on 100 Liter Ends Today

Updated: July 12, 2024

This review is by Homebrew Finds Contributor Brad Probert.  Brad is an engineer, expert homebrewer and experienced reviewer.  Grab a link to Brad’s website at the end of this review.


Limited Time Deal

William’s Brewing has select sizes of BrewZilla on sale for a limited time


Hands on Review BrewZilla Gen4

I’ve brewed on several different all-in-one units. Like any brew system, they each have their own strengths and weaknesses. I did a hands-on review of the Robobrew when it first came out in late 2016. It has since changed its name to BrewZilla and is on the 4th generation of the brew unit. As you’d expect with repeated generations, they’ve been able to focus on fixing deficiencies in their previous models and also introduce new features.

The basic premise of an all-in-one brewing system is that your mash and boil kettle are in the

same vessel. So just like Brew In A Bag, after mashing, you pull the grains out and the wort stays behind to be boiled. They use electricity for heat, so they can be used outdoors where you can reach power or indoors where you have a venting system that can take care of all the steam you make during your boil.

BrewZilla Without Jacket

Stamped Volume Markings

Here are some basic stats on the Gen4 BrewZilla. It’s available in a 35-Liter form (for 5-6 gallon batches) with either a 110V setup, or 220V. There is also a larger 65-Liter that is only 220V (targeted to 10-12 gallon batches). The 35L unit holds 9.25 gallons, the mash basket can hold up to 23.5 lbs. of grain, and its electric heating elements can output up to 1500W of power (110V system) or 2400W of power (220V system). The 65L unit holds 17.1 gallons, the mash basket holds 41.5 lbs. of grain, and 3500W of heating power. All the Gen4 units have a pump bolted into the base. The pump can be used not only for wort recirculation during the mash, but also to pump beer through your wort chiller apparatus (should you choose to not use the immersion chiller coil included with the BrewZilla). The pump is more modular and accessible than previous Gen models. To protect the pump from clogging with hop debris during the boil or whirlpool, there is a filter screen (a perforated stainless disc that sits at the bottom of the unit) that sits at the bottom of the kettle. The small magnetic drive pump has a pump head rating of 1.5 – 2.1 m (4.9 – 6.9 ft) and a max flow rate of 11-12 L/min (2.9 – 3.2 gal/min).

Control Panel Notification During Mash Profile

One of the key upgraded features of the Gen4 BrewZilla is the controller. RAPT Is Kegland’s line of wireless connected brewing devices. The BrewZilla now has a RAPT controller so it adds a lot of features that can be monitored and controlled over Wi-Fi. This includes basic things like monitoring temperature from your laptop/cell phone, but also allows you to program complex mash programs online and then download to your BrewZilla. You can also adjust control parameters on the fly such as pump output duty cycle and heater output level. If you get the optional Bluetooth thermometer, you can stick the temperature probe into the middle of your grain bed, and then have the controller use that as its control signal in combination with the built-in temperature sensor that sits on the floor of the unit.

Bluetooth Temp Probe in Middle of Mash

Although All-in-One units are essentially BIAB, they use a stainless steel basket with holes in the bottom of it instead of a bag, and call it a “malt pipe”. These provide functional improvements over a nylon bag. The obvious one is they are way easier to clean. But they also allow you to ensure you get full flow through your grain bed by having holes only on the bottom. This means recirculating wort has no sneak paths out the side. The other benefit is malt pipes have simple brackets/feet welded onto the outside that allow you to lift your wet grains up and prop the malt pipe on the brew rig to drain or sparge. The BrewZilla has 2 sets of feet for this. One set is halfway up, allowing you to do the deadlift of grain & wort halfway and then let the liquid level drain down. Then when you lift it the full height, it’s not as heavy. It’s simple, but makes the process much better.

Welded-on Carry Handle (top) and Tip Handle (bottom)

There is a cool feature in the BrewZilla which normally only comes on much higher end systems, and that’s the central drain. With a concave bottom with a drain at the lowest point in the center, you don’t have to leave wort behind or goof around with tilting it to get the last drops of wort out at the end. This also enables the malt pipe to extend down lower and thus you can hold more grain (30% more than their Gen3). If you compared to other All-in-one units in the “5 gallon batch” size range, the 23.5 lbs. grain capacity is 30 – 50% more. This of course only matters if you’re trying to make high gravity brews. The drain in the floor is plumbed to the inlet of the pump below, and then you can direct pump output either to an external spigot for fast/easy transfer of wort out after brewing, or up the recirculation pipe for wort to get directed down on top of the mash.

Polished Bottom with Center Drain and Built-in Temp Sensor to Side

Bottom Side of Pump Filter Plate

To help with mash efficiency and mash temperature uniformity, they offer a Heat Exchanger Dish, which is just a stainless dish/plate that sits below your malt pipe and above the central drain. Without this dish in place, the flow of recirculating wort tends to go through the center of your grain bed, and straight out the drain. With the dish there, it directs the flow around the full circumference before it gets to the drain, which helps ensure a broader portion of the grist sees the flow.

Another helpful option is the neoprene insulation jacket. This helps keep mash temperatures more consistent by cutting down heat loss through the walls of the unit. The jacket on BrewZilla also smartly covers the recirculation pipe to minimize heat loss during wort recirculation. The overall mash temperature response with a multi-step mash was impressive, with more detail provided in the Hands On section, below.

Hands on Trials

First off, all of the different parts were well made with good quality manufacturing. As I’ve found with all Kegland gear, it’s of good quality- but nothing flashy. The one exception was probably the smooth and highly polished dished bottom. That was flashy. And being a previous owner of a 1st Gen Robobrew, I was very happy to see the camlock fitting on the recirculation pipe and see that Kegland was obviously tuned in to customer feedback on their products.

Mashing-in Sequence

Sparging

I brewed three different batches before writing this review. Two of them followed a simple single temperature mash, and the third one I exercised the RAPT Controller more with a multi-step mash profile, with lots of monitoring via my smartphone. I was impressed with the mash efficiency I achieved. There can be a misconception that BIAB = lower mash efficiency, but really, it’s “full volume mash = lower efficiency”. I had previously done experiments with an Anvil Foundry that showed a sparge step can get you mash efficiencies > 80%. Therefore, my batches in the BrewZilla were all done with a sparge step. I rested the malt pipe at the top while pouring heated sparge water through it with a 1-gallon pitcher. The perforated plate sitting on top of the grain bed made it super simple to sparge like this and get a good water distribution pattern. The perforated plate also allowed me to push down very easily and squeeze out remaining liquid in the grains. If you’re in the school of thought that squeezing the grains is bad for your beer, this isn’t relevant for you. For the rest of us, being able to easily squeeze that out without making a mess was awesome. And it meant when I picked up the basket of spent grain, I didn’t have a trail of sugary malt drippings to clean up after. My first batch achieved 77% mash efficiency, the second one 80%, and the third 81%.

Recirc Flow Rate After CFC

I experimented a bit with the Bluetooth RAPT wireless thermometer, but I didn’t properly understand it at first. I thought the concept was I could choose whether to use the built-in sensor at the bottom of the unit or the Bluetooth thermometer, but that wasn’t the case. When you add the Bluetooth thermometer, it will then control to that temperature, but it still uses the built-in sensor as part of your heating in a way that lets you fine tune how the system as a whole responds to temperature steps in your mash. After tinkering with it a bit, I realized it has some really powerful potential, but requires a deeper dive and some experimentation to back it up. So I’ll save that for a future write-up.

Bluetooth RAPT Thermometer

My typical brew system uses a 10-gallon kettle with a pump recirculating wort through a 240V RIMS with a 3500W heating element. With that set-up, I get about 3.1 degrees/minute temperature rise when doing multi-step mash profiles. I was therefore expecting this 120V/1500W system to be slow but was shocked to find similar performance that averaged around 2.5 degrees/minute. I attributed this capability to the neoprene jacket. On the plus side, that means you can do multi-step mashes even on only a 120V outlet and not take all day. But leaving the lid on as you heat to a boil is still a must. With the large opening in its domed top, it still can allow any volatized compounds to flow out.

BrewZilla Mashing by Itself in Basement

I found the RAPT software a bit non-intuitive and as such, had a learning curve to it. Luckily, I did a trial run just with water in it so I could get a feel for where various controls were located and how it worked. I definitely recommend this before you try to do any multi-step mash program, or live monitoring of things from the App. Way less stressful when it’s just water! After I got the hang of it, I was able to monitor my mash well and know what was going on as it chugged away in the basement and I worked at my day job one floor above. One key thing I learned was the in-flight plotting of mash temperature isn’t a continuously updating graph, you have to hit refresh in the App to get the updated data that it is recording and holding. I assume this is for computing efficiency and Wi-Fi bandwidth load management. It was perfectly fine once I figured out how it worked.

Screenshot of RAPT Controller Interface

The RAPT Controller allows you to program in multi-step mashes. But it’s a bit clunky as you figure it out. When you build the profile up using the App or Web interface, that profile sits on the RAPT server. My brain kept wanting to think I was programming the controller directly on the unit, but that’s not how it works. So after you program in the profile, you have to download it to the controller on your unit for it to work. You do all of this through the RAPT portal, and it only requires your BrewZilla to be powered on to let you download to it. This would be cool if you could just export something from Brewfather and then import it in RAPT, but you can’t. However, when you think about it, you probably don’t have that many different mash profiles, so it’s not really a big deal.

Malt Pipe

Draining Malt Pipe

One super cool feature of the mash profile programming is Kegland finally did what many have wanted these controllers to do for a long time. Rather than open loop programming a temperature and a time and guesstimating how long it will take for your mash to reach that temperature, you can tell it to not start counting down your mash step timer until it reaches the temperature. So if you want a 45-minute rest at 150F, you don’t have to think about how long it will take to get to 150F, it just heats up, and then starts the 45-minute timer when you hit 150F. I really liked this. You are also able to set up notifications at either the beginning or end of a particular mash step. I had it send an alert to my phone once it had reached mashout temperature and thus had 10 minutes left in my mash. That was cool, too. This isn’t quite as simple as it sounds, though. What I found was if the PID controller didn’t overshoot my target temp, I spent several minutes closing in on the target, but didn’t hit the temperature to start your countdown timer. So I’d end up with long mash times. I did some experiments with PID gains and the Bluetooth probe that got this working as I wanted, but I’ll detail that in a later write-up.

Rolling Boil at 75-percent Power

There wasn’t a boil timer interface, the controller was really just geared to controlling & monitoring mash temperatures. Not a big deal, as my Brewfather boil timer works great for this, so it isn’t a feature RAPT needs to spend time making. I could easily maintain a robust boil if I wanted to, but I like to keep it at just a good rolling circulation, so I dialed down the heating element power to 75% and maintained a constant churn of the wort and allowed boil-off of 0.4 – 0.5 gallons per hour. And the filter dish at the bottom of the kettle worked great to keep hop debris out of the pump, but not restrict flow. I had a thick cake of hop mush at the end when it was time to clean. Cleaning was fast and easy with parts light and easy to pull out, come apart, and rinse. And with the built-in pump, it was also easy to fill the unit up with cleaning solution at the end, circulate it through the unit & my Counter Flow Chiller to get everything clean.

Chilling Wort Using CFC and Built-in Pump

For wort cooling at the end of the boil, I used the built-in pump and circulated wort through my CFC. With the camlock fitting on the BrewZilla, I could easily hook up my typical ½” silicone tubing hoses. I was unsure if the pump would be up to the job, but it handled it easily. I could get a good volume flow rate with the recirc valve wide open on the BrewZilla and could easily restrict it when I wanted a slower flow.

A couple of pro tips to wrap things up. First, is to make sure you add your grains to the malt pipe BEFORE you lower it into the vessel. This ensures the weight of the grain keeps the bottom plate in place, so that as you lower it down, the water doesn’t push the bottom plate out of position and create a sneak path for whole grains to get through. Second is to make sure you have the plug fully seated in your brew unit. This might sound stupidly logical, but with a 6-foot power cord, you might end up pushing the limits of where you want the unit to sit vs. where the outlet is you’re plugged into. I had the cable become partially unseated and I wasn’t aware- until I went to remove the cord at the end of a long session of PID controller experiments. If the cord isn’t fully seated, you get less electrical contact on the pins and less contact means higher heat as electricity flows through it. I ended up damaging the cord and the receptacle from overheating.

Conclusions

The BrewZilla Gen4 delivered. The controller worked great, and I absolutely loved the step mash ability to start the mash step timer using actual mash temperatures. The RAPT interface wasn’t quite as slick as I would’ve liked but overall worked flawlessly, with no glitches. And I was definitely surprised how well a mere 120V/1500W system could handle mash steps and boil intensity. The well-thought-out little pieces of the malt pipe and various recirculation designs showed to me a system that was engineered with actual brewing hours spent on the unit, which is great. I feel with all of this, I won’t have compromises on my brew day using an all-in-one system versus my bigger 2-vessel system. And that says a lot.

Special thanks to Kegland for providing the unit used for evaluation in this review.

Hands on Review BrewZilla Gen4

I’ve brewed on several different all-in-one units. Like any brew system, they each have their own strengths and weaknesses. I did a hands-on review of the Robobrew when it first came out in late 2016. It has since changed its name to BrewZilla and is on the 4th generation of the brew unit. As you’d expect with repeated generations, they’ve been able to focus on fixing deficiencies in their previous models and also introduce new features.

The basic premise of an all-in-one brewing system is that your mash and boil kettle are in the

same vessel. So just like Brew In A Bag, after mashing, you pull the grains out and the wort stays behind to be boiled. They use electricity for heat, so they can be used outdoors where you can reach power or indoors where you have a venting system that can take care of all the steam you make during your boil.

BrewZilla Without Jacket

Stamped Volume Markings

Here are some basic stats on the Gen4 BrewZilla. It’s available in a 35-Liter form (for 5-6 gallon batches) with either a 110V setup, or 220V. There is also a larger 65-Liter that is only 220V (targeted to 10-12 gallon batches). The 35L unit holds 9.25 gallons, the mash basket can hold up to 23.5 lbs. of grain, and its electric heating elements can output up to 1500W of power (110V system) or 2400W of power (220V system). The 65L unit holds 17.1 gallons, the mash basket holds 41.5 lbs. of grain, and 3500W of heating power. All the Gen4 units have a pump bolted into the base. The pump can be used not only for wort recirculation during the mash, but also to pump beer through your wort chiller apparatus (should you choose to not use the immersion chiller coil included with the BrewZilla). The pump is more modular and accessible than previous Gen models. To protect the pump from clogging with hop debris during the boil or whirlpool, there is a filter screen (a perforated stainless disc that sits at the bottom of the unit) that sits at the bottom of the kettle. The small magnetic drive pump has a pump head rating of 1.5 – 2.1 m (4.9 – 6.9 ft) and a max flow rate of 11-12 L/min (2.9 – 3.2 gal/min).

Control Panel Notification During Mash Profile

One of the key upgraded features of the Gen4 BrewZilla is the controller. RAPT Is Kegland’s line of wireless connected brewing devices. The BrewZilla now has a RAPT controller so it adds a lot of features that can be monitored and controlled over Wi-Fi. This includes basic things like monitoring temperature from your laptop/cell phone, but also allows you to program complex mash programs online and then download to your BrewZilla. You can also adjust control parameters on the fly such as pump output duty cycle and heater output level. If you get the optional Bluetooth thermometer, you can stick the temperature probe into the middle of your grain bed, and then have the controller use that as its control signal in combination with the built-in temperature sensor that sits on the floor of the unit.

Bluetooth Temp Probe in Middle of Mash

Although All-in-One units are essentially BIAB, they use a stainless steel basket with holes in the bottom of it instead of a bag, and call it a “malt pipe”. These provide functional improvements over a nylon bag. The obvious one is they are way easier to clean. But they also allow you to ensure you get full flow through your grain bed by having holes only on the bottom. This means recirculating wort has no sneak paths out the side. The other benefit is malt pipes have simple brackets/feet welded onto the outside that allow you to lift your wet grains up and prop the malt pipe on the brew rig to drain or sparge. The BrewZilla has 2 sets of feet for this. One set is halfway up, allowing you to do the deadlift of grain & wort halfway and then let the liquid level drain down. Then when you lift it the full height, it’s not as heavy. It’s simple, but makes the process much better.

Welded-on Carry Handle (top) and Tip Handle (bottom)

There is a cool feature in the BrewZilla which normally only comes on much higher end systems, and that’s the central drain. With a concave bottom with a drain at the lowest point in the center, you don’t have to leave wort behind or goof around with tilting it to get the last drops of wort out at the end. This also enables the malt pipe to extend down lower and thus you can hold more grain (30% more than their Gen3). If you compared to other All-in-one units in the “5 gallon batch” size range, the 23.5 lbs. grain capacity is 30 – 50% more. This of course only matters if you’re trying to make high gravity brews. The drain in the floor is plumbed to the inlet of the pump below, and then you can direct pump output either to an external spigot for fast/easy transfer of wort out after brewing, or up the recirculation pipe for wort to get directed down on top of the mash.

Polished Bottom with Center Drain and Built-in Temp Sensor to Side

Bottom Side of Pump Filter Plate

To help with mash efficiency and mash temperature uniformity, they offer a Heat Exchanger Dish, which is just a stainless dish/plate that sits below your malt pipe and above the central drain. Without this dish in place, the flow of recirculating wort tends to go through the center of your grain bed, and straight out the drain. With the dish there, it directs the flow around the full circumference before it gets to the drain, which helps ensure a broader portion of the grist sees the flow.

Another helpful option is the neoprene insulation jacket. This helps keep mash temperatures more consistent by cutting down heat loss through the walls of the unit. The jacket on BrewZilla also smartly covers the recirculation pipe to minimize heat loss during wort recirculation. The overall mash temperature response with a multi-step mash was impressive, with more detail provided in the Hands On section, below.

Hands on Trials

First off, all of the different parts were well made with good quality manufacturing. As I’ve found with all Kegland gear, it’s of good quality- but nothing flashy. The one exception was probably the smooth and highly polished dished bottom. That was flashy. And being a previous owner of a 1st Gen Robobrew, I was very happy to see the camlock fitting on the recirculation pipe and see that Kegland was obviously tuned in to customer feedback on their products.

Mashing-in Sequence

Sparging

I brewed three different batches before writing this review. Two of them followed a simple single temperature mash, and the third one I exercised the RAPT Controller more with a multi-step mash profile, with lots of monitoring via my smartphone. I was impressed with the mash efficiency I achieved. There can be a misconception that BIAB = lower mash efficiency, but really, it’s “full volume mash = lower efficiency”. I had previously done experiments with an Anvil Foundry that showed a sparge step can get you mash efficiencies > 80%. Therefore, my batches in the BrewZilla were all done with a sparge step. I rested the malt pipe at the top while pouring heated sparge water through it with a 1-gallon pitcher. The perforated plate sitting on top of the grain bed made it super simple to sparge like this and get a good water distribution pattern. The perforated plate also allowed me to push down very easily and squeeze out remaining liquid in the grains. If you’re in the school of thought that squeezing the grains is bad for your beer, this isn’t relevant for you. For the rest of us, being able to easily squeeze that out without making a mess was awesome. And it meant when I picked up the basket of spent grain, I didn’t have a trail of sugary malt drippings to clean up after. My first batch achieved 77% mash efficiency, the second one 80%, and the third 81%.

Recirc Flow Rate After CFC

I experimented a bit with the Bluetooth RAPT wireless thermometer, but I didn’t properly understand it at first. I thought the concept was I could choose whether to use the built-in sensor at the bottom of the unit or the Bluetooth thermometer, but that wasn’t the case. When you add the Bluetooth thermometer, it will then control to that temperature, but it still uses the built-in sensor as part of your heating in a way that lets you fine tune how the system as a whole responds to temperature steps in your mash. After tinkering with it a bit, I realized it has some really powerful potential, but requires a deeper dive and some experimentation to back it up. So I’ll save that for a future write-up.

Bluetooth RAPT Thermometer

My typical brew system uses a 10-gallon kettle with a pump recirculating wort through a 240V RIMS with a 3500W heating element. With that set-up, I get about 3.1 degrees/minute temperature rise when doing multi-step mash profiles. I was therefore expecting this 120V/1500W system to be slow but was shocked to find similar performance that averaged around 2.5 degrees/minute. I attributed this capability to the neoprene jacket. On the plus side, that means you can do multi-step mashes even on only a 120V outlet and not take all day. But leaving the lid on as you heat to a boil is still a must. With the large opening in its domed top, it still can allow any volatized compounds to flow out.

BrewZilla Mashing by Itself in Basement

I found the RAPT software a bit non-intuitive and as such, had a learning curve to it. Luckily, I did a trial run just with water in it so I could get a feel for where various controls were located and how it worked. I definitely recommend this before you try to do any multi-step mash program, or live monitoring of things from the App. Way less stressful when it’s just water! After I got the hang of it, I was able to monitor my mash well and know what was going on as it chugged away in the basement and I worked at my day job one floor above. One key thing I learned was the in-flight plotting of mash temperature isn’t a continuously updating graph, you have to hit refresh in the App to get the updated data that it is recording and holding. I assume this is for computing efficiency and Wi-Fi bandwidth load management. It was perfectly fine once I figured out how it worked.

Screenshot of RAPT Controller Interface

The RAPT Controller allows you to program in multi-step mashes. But it’s a bit clunky as you figure it out. When you build the profile up using the App or Web interface, that profile sits on the RAPT server. My brain kept wanting to think I was programming the controller directly on the unit, but that’s not how it works. So after you program in the profile, you have to download it to the controller on your unit for it to work. You do all of this through the RAPT portal, and it only requires your BrewZilla to be powered on to let you download to it. This would be cool if you could just export something from Brewfather and then import it in RAPT, but you can’t. However, when you think about it, you probably don’t have that many different mash profiles, so it’s not really a big deal.

Malt Pipe

Draining Malt Pipe

One super cool feature of the mash profile programming is Kegland finally did what many have wanted these controllers to do for a long time. Rather than open loop programming a temperature and a time and guesstimating how long it will take for your mash to reach that temperature, you can tell it to not start counting down your mash step timer until it reaches the temperature. So if you want a 45-minute rest at 150F, you don’t have to think about how long it will take to get to 150F, it just heats up, and then starts the 45-minute timer when you hit 150F. I really liked this. You are also able to set up notifications at either the beginning or end of a particular mash step. I had it send an alert to my phone once it had reached mashout temperature and thus had 10 minutes left in my mash. That was cool, too. This isn’t quite as simple as it sounds, though. What I found was if the PID controller didn’t overshoot my target temp, I spent several minutes closing in on the target, but didn’t hit the temperature to start your countdown timer. So I’d end up with long mash times. I did some experiments with PID gains and the Bluetooth probe that got this working as I wanted, but I’ll detail that in a later write-up.

Rolling Boil at 75-percent Power

There wasn’t a boil timer interface, the controller was really just geared to controlling & monitoring mash temperatures. Not a big deal, as my Brewfather boil timer works great for this, so it isn’t a feature RAPT needs to spend time making. I could easily maintain a robust boil if I wanted to, but I like to keep it at just a good rolling circulation, so I dialed down the heating element power to 75% and maintained a constant churn of the wort and allowed boil-off of 0.4 – 0.5 gallons per hour. And the filter dish at the bottom of the kettle worked great to keep hop debris out of the pump, but not restrict flow. I had a thick cake of hop mush at the end when it was time to clean. Cleaning was fast and easy with parts light and easy to pull out, come apart, and rinse. And with the built-in pump, it was also easy to fill the unit up with cleaning solution at the end, circulate it through the unit & my Counter Flow Chiller to get everything clean.

Chilling Wort Using CFC and Built-in Pump

For wort cooling at the end of the boil, I used the built-in pump and circulated wort through my CFC. With the camlock fitting on the BrewZilla, I could easily hook up my typical ½” silicone tubing hoses. I was unsure if the pump would be up to the job, but it handled it easily. I could get a good volume flow rate with the recirc valve wide open on the BrewZilla and could easily restrict it when I wanted a slower flow.

A couple of pro tips to wrap things up. First, is to make sure you add your grains to the malt pipe BEFORE you lower it into the vessel. This ensures the weight of the grain keeps the bottom plate in place, so that as you lower it down, the water doesn’t push the bottom plate out of position and create a sneak path for whole grains to get through. Second is to make sure you have the plug fully seated in your brew unit. This might sound stupidly logical, but with a 6-foot power cord, you might end up pushing the limits of where you want the unit to sit vs. where the outlet is you’re plugged into. I had the cable become partially unseated and I wasn’t aware- until I went to remove the cord at the end of a long session of PID controller experiments. If the cord isn’t fully seated, you get less electrical contact on the pins and less contact means higher heat as electricity flows through it. I ended up damaging the cord and the receptacle from overheating.

Conclusions

The BrewZilla Gen4 delivered. The controller worked great, and I absolutely loved the step mash ability to start the mash step timer using actual mash temperatures. The RAPT interface wasn’t quite as slick as I would’ve liked but overall worked flawlessly, with no glitches. And I was definitely surprised how well a mere 120V/1500W system could handle mash steps and boil intensity. The well-thought-out little pieces of the malt pipe and various recirculation designs showed to me a system that was engineered with actual brewing hours spent on the unit, which is great. I feel with all of this, I won’t have compromises on my brew day using an all-in-one system versus my bigger 2-vessel system. And that says a lot.

Special thanks to Kegland for providing the unit used for evaluation in this review.

For wort cooling at the end of the boil, I used the built-in pump and circulated wort through my CFC. With the camlock fitting on the BrewZilla, I could easily hook up my typical ½” silicone tubing hoses. I was unsure if the pump would be up to the job, but it handled it easily. I could get a good volume flow rate with the recirc valve wide open on the BrewZilla and could easily restrict it when I wanted a slower flow.

A couple of pro tips to wrap things up. First, is to make sure you add your grains to the malt pipe BEFORE you lower it into the vessel. This ensures the weight of the grain keeps the bottom plate in place, so that as you lower it down, the water doesn’t push the bottom plate out of position and create a sneak path for whole grains to get through. Second is to make sure you have the plug fully seated in your brew unit. This might sound stupidly logical, but with a 6-foot power cord, you might end up pushing the limits of where you want the unit to sit vs. where the outlet is you’re plugged into. I had the cable become partially unseated and I wasn’t aware- until I went to remove the cord at the end of a long session of PID controller experiments. If the cord isn’t fully seated, you get less electrical contact on the pins and less contact means higher heat as electricity flows through it. I ended up damaging the cord and the receptacle from overheating.

Conclusions

The BrewZilla Gen4 delivered. The controller worked great, and I absolutely loved the step mash ability to start the mash step timer using actual mash temperatures. The RAPT interface wasn’t quite as slick as I would’ve liked but overall worked flawlessly, with no glitches. And I was definitely surprised how well a mere 120V/1500W system could handle mash steps and boil intensity. The well-thought-out little pieces of the malt pipe and various recirculation designs showed to me a system that was engineered with actual brewing hours spent on the unit, which is great. I feel with all of this, I won’t have compromises on my brew day using an all-in-one system versus my bigger 2-vessel system. And that says a lot.

Special thanks to Kegland for providing the unit used for evaluation in this review.

Hands on Review BrewZilla Gen4

I’ve brewed on several different all-in-one units. Like any brew system, they each have their own strengths and weaknesses. I did a hands-on review of the Robobrew when it first came out in late 2016. It has since changed its name to BrewZilla and is on the 4th generation of the brew unit. As you’d expect with repeated generations, they’ve been able to focus on fixing deficiencies in their previous models and also introduce new features.

The basic premise of an all-in-one brewing system is that your mash and boil kettle are in the

same vessel. So just like Brew In A Bag, after mashing, you pull the grains out and the wort stays behind to be boiled. They use electricity for heat, so they can be used outdoors where you can reach power or indoors where you have a venting system that can take care of all the steam you make during your boil.

BrewZilla Without Jacket

Stamped Volume Markings

Here are some basic stats on the Gen4 BrewZilla. It’s available in a 35-Liter form (for 5-6 gallon batches) with either a 110V setup, or 220V. There is also a larger 65-Liter that is only 220V (targeted to 10-12 gallon batches). The 35L unit holds 9.25 gallons, the mash basket can hold up to 23.5 lbs. of grain, and its electric heating elements can output up to 1500W of power (110V system) or 2400W of power (220V system). The 65L unit holds 17.1 gallons, the mash basket holds 41.5 lbs. of grain, and 3500W of heating power. All the Gen4 units have a pump bolted into the base. The pump can be used not only for wort recirculation during the mash, but also to pump beer through your wort chiller apparatus (should you choose to not use the immersion chiller coil included with the BrewZilla). The pump is more modular and accessible than previous Gen models. To protect the pump from clogging with hop debris during the boil or whirlpool, there is a filter screen (a perforated stainless disc that sits at the bottom of the unit) that sits at the bottom of the kettle. The small magnetic drive pump has a pump head rating of 1.5 – 2.1 m (4.9 – 6.9 ft) and a max flow rate of 11-12 L/min (2.9 – 3.2 gal/min).

Control Panel Notification During Mash Profile

One of the key upgraded features of the Gen4 BrewZilla is the controller. RAPT Is Kegland’s line of wireless connected brewing devices. The BrewZilla now has a RAPT controller so it adds a lot of features that can be monitored and controlled over Wi-Fi. This includes basic things like monitoring temperature from your laptop/cell phone, but also allows you to program complex mash programs online and then download to your BrewZilla. You can also adjust control parameters on the fly such as pump output duty cycle and heater output level. If you get the optional Bluetooth thermometer, you can stick the temperature probe into the middle of your grain bed, and then have the controller use that as its control signal in combination with the built-in temperature sensor that sits on the floor of the unit.

Bluetooth Temp Probe in Middle of Mash

Although All-in-One units are essentially BIAB, they use a stainless steel basket with holes in the bottom of it instead of a bag, and call it a “malt pipe”. These provide functional improvements over a nylon bag. The obvious one is they are way easier to clean. But they also allow you to ensure you get full flow through your grain bed by having holes only on the bottom. This means recirculating wort has no sneak paths out the side. The other benefit is malt pipes have simple brackets/feet welded onto the outside that allow you to lift your wet grains up and prop the malt pipe on the brew rig to drain or sparge. The BrewZilla has 2 sets of feet for this. One set is halfway up, allowing you to do the deadlift of grain & wort halfway and then let the liquid level drain down. Then when you lift it the full height, it’s not as heavy. It’s simple, but makes the process much better.

Welded-on Carry Handle (top) and Tip Handle (bottom)

There is a cool feature in the BrewZilla which normally only comes on much higher end systems, and that’s the central drain. With a concave bottom with a drain at the lowest point in the center, you don’t have to leave wort behind or goof around with tilting it to get the last drops of wort out at the end. This also enables the malt pipe to extend down lower and thus you can hold more grain (30% more than their Gen3). If you compared to other All-in-one units in the “5 gallon batch” size range, the 23.5 lbs. grain capacity is 30 – 50% more. This of course only matters if you’re trying to make high gravity brews. The drain in the floor is plumbed to the inlet of the pump below, and then you can direct pump output either to an external spigot for fast/easy transfer of wort out after brewing, or up the recirculation pipe for wort to get directed down on top of the mash.

Polished Bottom with Center Drain and Built-in Temp Sensor to Side

Bottom Side of Pump Filter Plate

To help with mash efficiency and mash temperature uniformity, they offer a Heat Exchanger Dish, which is just a stainless dish/plate that sits below your malt pipe and above the central drain. Without this dish in place, the flow of recirculating wort tends to go through the center of your grain bed, and straight out the drain. With the dish there, it directs the flow around the full circumference before it gets to the drain, which helps ensure a broader portion of the grist sees the flow.

Another helpful option is the neoprene insulation jacket. This helps keep mash temperatures more consistent by cutting down heat loss through the walls of the unit. The jacket on BrewZilla also smartly covers the recirculation pipe to minimize heat loss during wort recirculation. The overall mash temperature response with a multi-step mash was impressive, with more detail provided in the Hands On section, below.

Hands on Trials

First off, all of the different parts were well made with good quality manufacturing. As I’ve found with all Kegland gear, it’s of good quality- but nothing flashy. The one exception was probably the smooth and highly polished dished bottom. That was flashy. And being a previous owner of a 1st Gen Robobrew, I was very happy to see the camlock fitting on the recirculation pipe and see that Kegland was obviously tuned in to customer feedback on their products.

Mashing-in Sequence

Sparging

I brewed three different batches before writing this review. Two of them followed a simple single temperature mash, and the third one I exercised the RAPT Controller more with a multi-step mash profile, with lots of monitoring via my smartphone. I was impressed with the mash efficiency I achieved. There can be a misconception that BIAB = lower mash efficiency, but really, it’s “full volume mash = lower efficiency”. I had previously done experiments with an Anvil Foundry that showed a sparge step can get you mash efficiencies > 80%. Therefore, my batches in the BrewZilla were all done with a sparge step. I rested the malt pipe at the top while pouring heated sparge water through it with a 1-gallon pitcher. The perforated plate sitting on top of the grain bed made it super simple to sparge like this and get a good water distribution pattern. The perforated plate also allowed me to push down very easily and squeeze out remaining liquid in the grains. If you’re in the school of thought that squeezing the grains is bad for your beer, this isn’t relevant for you. For the rest of us, being able to easily squeeze that out without making a mess was awesome. And it meant when I picked up the basket of spent grain, I didn’t have a trail of sugary malt drippings to clean up after. My first batch achieved 77% mash efficiency, the second one 80%, and the third 81%.

Recirc Flow Rate After CFC

I experimented a bit with the Bluetooth RAPT wireless thermometer, but I didn’t properly understand it at first. I thought the concept was I could choose whether to use the built-in sensor at the bottom of the unit or the Bluetooth thermometer, but that wasn’t the case. When you add the Bluetooth thermometer, it will then control to that temperature, but it still uses the built-in sensor as part of your heating in a way that lets you fine tune how the system as a whole responds to temperature steps in your mash. After tinkering with it a bit, I realized it has some really powerful potential, but requires a deeper dive and some experimentation to back it up. So I’ll save that for a future write-up.

Bluetooth RAPT Thermometer

My typical brew system uses a 10-gallon kettle with a pump recirculating wort through a 240V RIMS with a 3500W heating element. With that set-up, I get about 3.1 degrees/minute temperature rise when doing multi-step mash profiles. I was therefore expecting this 120V/1500W system to be slow but was shocked to find similar performance that averaged around 2.5 degrees/minute. I attributed this capability to the neoprene jacket. On the plus side, that means you can do multi-step mashes even on only a 120V outlet and not take all day. But leaving the lid on as you heat to a boil is still a must. With the large opening in its domed top, it still can allow any volatized compounds to flow out.

BrewZilla Mashing by Itself in Basement

I found the RAPT software a bit non-intuitive and as such, had a learning curve to it. Luckily, I did a trial run just with water in it so I could get a feel for where various controls were located and how it worked. I definitely recommend this before you try to do any multi-step mash program, or live monitoring of things from the App. Way less stressful when it’s just water! After I got the hang of it, I was able to monitor my mash well and know what was going on as it chugged away in the basement and I worked at my day job one floor above. One key thing I learned was the in-flight plotting of mash temperature isn’t a continuously updating graph, you have to hit refresh in the App to get the updated data that it is recording and holding. I assume this is for computing efficiency and Wi-Fi bandwidth load management. It was perfectly fine once I figured out how it worked.

Screenshot of RAPT Controller Interface

The RAPT Controller allows you to program in multi-step mashes. But it’s a bit clunky as you figure it out. When you build the profile up using the App or Web interface, that profile sits on the RAPT server. My brain kept wanting to think I was programming the controller directly on the unit, but that’s not how it works. So after you program in the profile, you have to download it to the controller on your unit for it to work. You do all of this through the RAPT portal, and it only requires your BrewZilla to be powered on to let you download to it. This would be cool if you could just export something from Brewfather and then import it in RAPT, but you can’t. However, when you think about it, you probably don’t have that many different mash profiles, so it’s not really a big deal.

Malt Pipe

Draining Malt Pipe

One super cool feature of the mash profile programming is Kegland finally did what many have wanted these controllers to do for a long time. Rather than open loop programming a temperature and a time and guesstimating how long it will take for your mash to reach that temperature, you can tell it to not start counting down your mash step timer until it reaches the temperature. So if you want a 45-minute rest at 150F, you don’t have to think about how long it will take to get to 150F, it just heats up, and then starts the 45-minute timer when you hit 150F. I really liked this. You are also able to set up notifications at either the beginning or end of a particular mash step. I had it send an alert to my phone once it had reached mashout temperature and thus had 10 minutes left in my mash. That was cool, too. This isn’t quite as simple as it sounds, though. What I found was if the PID controller didn’t overshoot my target temp, I spent several minutes closing in on the target, but didn’t hit the temperature to start your countdown timer. So I’d end up with long mash times. I did some experiments with PID gains and the Bluetooth probe that got this working as I wanted, but I’ll detail that in a later write-up.

Rolling Boil at 75-percent Power

There wasn’t a boil timer interface, the controller was really just geared to controlling & monitoring mash temperatures. Not a big deal, as my Brewfather boil timer works great for this, so it isn’t a feature RAPT needs to spend time making. I could easily maintain a robust boil if I wanted to, but I like to keep it at just a good rolling circulation, so I dialed down the heating element power to 75% and maintained a constant churn of the wort and allowed boil-off of 0.4 – 0.5 gallons per hour. And the filter dish at the bottom of the kettle worked great to keep hop debris out of the pump, but not restrict flow. I had a thick cake of hop mush at the end when it was time to clean. Cleaning was fast and easy with parts light and easy to pull out, come apart, and rinse. And with the built-in pump, it was also easy to fill the unit up with cleaning solution at the end, circulate it through the unit & my Counter Flow Chiller to get everything clean.

Chilling Wort Using CFC and Built-in Pump

For wort cooling at the end of the boil, I used the built-in pump and circulated wort through my CFC. With the camlock fitting on the BrewZilla, I could easily hook up my typical ½” silicone tubing hoses. I was unsure if the pump would be up to the job, but it handled it easily. I could get a good volume flow rate with the recirc valve wide open on the BrewZilla and could easily restrict it when I wanted a slower flow.

A couple of pro tips to wrap things up. First, is to make sure you add your grains to the malt pipe BEFORE you lower it into the vessel. This ensures the weight of the grain keeps the bottom plate in place, so that as you lower it down, the water doesn’t push the bottom plate out of position and create a sneak path for whole grains to get through. Second is to make sure you have the plug fully seated in your brew unit. This might sound stupidly logical, but with a 6-foot power cord, you might end up pushing the limits of where you want the unit to sit vs. where the outlet is you’re plugged into. I had the cable become partially unseated and I wasn’t aware- until I went to remove the cord at the end of a long session of PID controller experiments. If the cord isn’t fully seated, you get less electrical contact on the pins and less contact means higher heat as electricity flows through it. I ended up damaging the cord and the receptacle from overheating.

Conclusions

The BrewZilla Gen4 delivered. The controller worked great, and I absolutely loved the step mash ability to start the mash step timer using actual mash temperatures. The RAPT interface wasn’t quite as slick as I would’ve liked but overall worked flawlessly, with no glitches. And I was definitely surprised how well a mere 120V/1500W system could handle mash steps and boil intensity. The well-thought-out little pieces of the malt pipe and various recirculation designs showed to me a system that was engineered with actual brewing hours spent on the unit, which is great. I feel with all of this, I won’t have compromises on my brew day using an all-in-one system versus my bigger 2-vessel system. And that says a lot.
