Stainless Steel False Bottom for BIAB

BIABbottom15-2T

Stainless Steel False Bottom designed to keep your BIAB bag off the bottom of your kettle.

More from Brew Hardware

“First is a false bottom specifically designed for Brew In A Bag process. When you use a mesh bag in a pot, whether it’s directly fired on a burner or heated electrically, you want to keep the bag off the bottom. Typical homebrew false bottoms have really small holes and cut off the free flow that mesh bags are know for. Another less desirable choice is a steamer rack or tray that is found in kitchen shops, but none of those are stainless steel.

Our units start with 1.25mm 304SS welded wire mesh on 1/2″ centers. The mesh is supported by a double outer ring, both on top and bottom of the mesh and a pair of cross braces across the middle. This support material is nearly 1/4” in diameter an very sturdy. The legs are made of M8 metric bolts and are threaded into five nuts that are welded to the mesh. This modular leg style allows for just about any height you need just by changing out the length of the bolts.

OPTIONS:
You have the choice of several lengths during purchase, electable in the drop down menu. Note that if you select “no legs”, the screen still has the welded nuts that will accept legs in the future. Without the bolt legs, the screen will sit about 1/4″ off the bottom supported by the bottom rolled ring.

While it uses a max of 5 legs, you can use it without the center leg in case your heating element is in the way.

Again, make no mistake about it. If you see another product like this on any restaurant supply store, amazon or ebay, know that they are all chrome plated steel and they will rust.”

 

This is available in three sizes, depending on your kettle – 13″, 14″ and 17.5″

Guest Post: Brew In a Bag – Bag Material – Does it Matter? by Rex Slagel + 10% Off

Brew in a Bag Homebrew Bag MaterialSpecial Thanks to Rex Slagel for this Guest Post!  Read more about Rex below

So you’re either itching to move to all grain but either don’t have the budget, space, or you just don’t want to spend $750 to $1,500 on three vessel (3V) set up. Maybe you just brewed with a buddy on your 3V system while he brewed using a fabric filter aka – brew in a bag – and he was having a homebrew while you were adding your first hop additions, or you used to brew and then life happened so those six hour brew days are just not possible anymore…but you still want to brew! Using a fabric filter solves all those issues. But, can it really be that simple, is the beer worth drinking, and what type of bag should I use?

I’ll first say that there have been many brewing competitions won using a fabric filter. In fact the 2014 AHA home brewer of the year Robert Helferding now brews exclusively using this method. Here’s what he said about it:

“I started BIAB about a year ago and am a huge fan and advocate of the brewing method. The only weak spot I found was the bag itself. The Brew Bag® is my fifth purchased bag in less than a year — others were not fine enough, didn’t last past a few brews or were cheaply made and fell apart. My wife had made a bag that was pretty darn good… but did not have webbing handles and had to be lifted with a strainer from the brew kettle. She said a new sewing machine would help… I brewed a batch of Porter using the same recipe I have used for BIAB before. I milled the grain at .30 instead of .37 to test if the bag was going to work for me. At the end of the brew my OG was .06 points higher! Good clean wort and easy as a breeze to lift it out. I use a block and tackle suspended over the pot to remove the bag. If you are just getting into all-grain I urge you to start with Brew in a Bag. If you are already brewing in a 2 or 3-vessel system, give BIAB a try. Less work, less cleanup, and less time in the brew day.”

Because it impacts efficiency, clarity, draining properties, and longevity, let’s talk about the fabric used by BIAB brewers. You’ve heard of guys using paint strainers, panty hose, and muslin bags like you get in the extract kits. While these do strain the mash, they each have a major flaw that is based on the fiber used – but using them to strain wort still results in beer.

Paint strainers are made of nylon, which is fine except that the threads per inch (TPI) is only 35 or so, and that lets a lot of husk pass through to the wort. They are also very easy to tear and are not made to fit every kettle so the bag can constrict the grain and impede the water to grain (WTGR) contact and thus conversion time.

Brew in a Bag Homebrew Bag Material

Panty hose – well just panty hose. Made of nylon and spandex the material stretches, is easily torn and just can’t hold much grain. That’s all I have to say.

Muslin is cotton and will work a few times, but because cotton is “hairy” (see photo) it absorbs and retains the grain bits, cannot be cleaned well and is prone to bacterial growth. It also degrades when exposed to moisture and cannot be used as a hop bag.

Brew in a Bag Homebrew Bag Material

So what material is food safe, woven fine enough to strain grain husk, can withstand boiling, is very strong, “slick” so it cleans easily and does not harbor bacteria, does not absorb water, and can be used over and over? It’s called Voile – a multi or monofilament polyester used in all manner of applications. It is commonly found in fabric stores and is generally less than $5 per yard. Many home brewers buy Voile curtains to make bags…and it works!

The photo below is Voile magnified so you can compare cotton fibers to polyester fibers. Notice the lack of loose fibers on the Voile and how uniform the openings are. Nylon, like polyester is also an extruded fiber and would look similar under a microscope, but because it is more elastic than Voile it is not a good choice for a brew bag, particularly for heavy grain bills.

This is a close-up of Voile as used in a brew bag. The strapping is added to aid lifting and transfer part of the weight of the grain off the material.

So why does fabric composition matter? When mashing the primary objective is to move the wort from the mash tun to the boil kettle, so when the flow rate out of the tun is high the wort (sugar water) moves with less friction across the grain and out of the bag. And a bag provides more surface area for filtering. Using a fabric that not only filters well but also allows sufficient drainage to carry the sugar is of great benefit.

This “less friction” logic is the primary reason for the 170º mash out / sparge, but some folk’s say its primary purpose is to set the sugar profile by denaturing the enzymes – and it does that. But high-temp sparging or mashing out occurs AFTER the majority of conversion has taken place, so in the thirty to sixty minutes it typically takes to sparge, there are not enough enzymes left, or starch to act on that could change the sugar profile to any noticeable degree. And because of the highly controlled modification (malting) process of the grains we use today, except in cases of raw or non-modified grain, this eliminates the need for a step-mash or a mash out.

When using a fabric filter and full mash volume, the pre-boil sugar profile (gravity) can easily be confirmed with a refractometer, but that won’t work for a 3V sparge brewer because the pre-boil gravity is not determined until the diluted volume in the kettle is reached. 3V mash tun gravity can be measured and conversion confirmed complete, but because the tun gravity measurement is different than the kettle gravity, the process is not controlled and thus confirmation of the sugar profile is inaccurate.

So if the above information is true, why the 170º mash out? Lot’s of 3V brewers do it to raise the viscosity of the wort so it moves through the grain bed with less restriction – hotter = thinner.

This brings us back to bag composition and out-flow rate. Just like a thin mash and typical 3V pick up and a wide open ball valve, a bag that has too few TPI will not filter the grain husks out of the wort, so clarity is affected. This can cure itself via time and temperature, but if you can eliminate the husk, why not?

And like a thick 3V mash, a bag that has too many TPI will restrict flow, impact efficiency, and take a long time to drain. We’re looking for the Goldilocks of brew bag material – and that’s Voile. The fabric has fairly uniform openings (as in the photo) of ~210 micron = to  #70 wire mesh and is very durable.  Most grain mills are set between .030” and .045” while the holes in the bag are 210 micron or.0083”, so the grain husks and chunks are left behind in the bag as the wort flows through the holes in the fabric. We can conclude that choice of fabric for filtering wort does matter.

So when you’re thinking you’d like to get back into brewing, or save some time and money, do a bit of research on using a fabric filter. It’s just not for BIAB anymore!
