One of the easiest options to serve your homebrew on the go is filling up a growler.  See below for tips on getting a good growler fill.

Standard growlers are easy to be had and… easy to break.  This section focuses on stainless steel and other unique offerings.

About Vacuum Insulation: Vacuum insulation helps keep beer cold for a long, long time (I’ve seen quoted times of 24+ hours – that’s going to be dependent upon conditions) and also resists or completely eliminates sweating.  These also generally look amazing.  They’re also great because you can take them to the park, beach or pool without being concerned about broken glass.

Neoprene Growler Carriers: These add an additional layer of insulation and protection to your growler.  A number of models and sizes are available.  Some offer additional features like shoulder straps and storage compartments.  Make sure the one you buy is compatible with your growler.  Search “neoprene growler carrier” on Amazon

Carbonation Caps

Carbonation caps allow you to pressurize your beer inside of a compatible 1 or 2 Liter PET bottle for quick carbonation and transport.  Fill the 1L or 2L Bottle just like you would a growler, put on a carbonating cap and pressurize for easy transport.  You can squeeze the bottle to expel extra head space prior to pressurizing with CO2.  When you pressurize the head space is filled up with CO2.  You can also use carbonation caps to help fine tune carbonation levels or force carbonate quickly.

Note: When multiple suppliers are mentioned, products may not be identical to the pictured item.

A Growler Sized Ball Lock Keg from Kegland!

This growler sized ball lock keg straddles the line between growler and small draft system. Add on a faucet and CO2 source and you have a small draft system. It’s actually a littler larger than growler size. Check out my Hands on Review for lots more info.

Small Draft Systems

Small kegging setups that lend themselves to easy transport.  You can either fill from your kegerator or bottle condition directly in these. General sizes are 5L, 1.5 gallon, 1.75 gallon and 2.5 gallon.

Benefits of Smaller Kegs Beyond Portable Serving: Smaller 2.5 to 3 gallon kegs are great for splitting batches, small batch brewers, doing one-off beers from split from a 5 gallon batch… and for easily serving on the go.

Tips and Tools for Filling Growlers and Small Draft Containers

Filling a growler or small draft dispenser from your draft setup is an easy and straightforward process.

  1. Start with a clean growler.  Use some growler cleaning tabs, PBW or your favorite homebrewing cleanser.  Refrain from using dish soaps and the like.  Thoroughly rinse your growler after cleaning.  If you’re not going to use it right away, let it air dry.  I always store my growlers with the cap off.  Starting with a clean growler is important for general cleanliness and food safety, but it also makes filling your growler easier.  Spots and such can serve as nucleation points causing unnecessary foam during the fill.
  2. A warm growler can lead to excessive foaming.  Start with a cold growler.  I suggest putting your growler directly in your kegerator so it’s the same temperature as your beer.  This will help to reduce foaming.
  3. Having a wet growler also helps reduce foam.  Put properly mixed Star San solution in your growler prior to chilling, swirl it around to coat all surfaces and discard just prior to filling.  If you’ll be drinking the growler right away, you can skip the Star San and just use fresh, cold tap water.
  4. Turn down the pressure.  Serving pressure is generally around 10 PSI, depending on how your system is tuned.  That makes for too quick of a fill and too much foam.  Turn down the pressure on your CO2 regulator to 3 or 4 psi to fill your growler slowly.  Remember to purge keg headspace after decreasing your regulator’s PSI setting.
  5. Affix a growler filler or length of tubing to your faucet.  If you’re using picnic taps a 3/8″ ID section of tubing should fit nicely on the end of your taps.  If you’re using a Perlick style faucet, a section of 1/2″ ID tubing should fit on your faucet.  Make sure the tubing is long enough to hit the bottom of the growler.  Filling from the bottom up should reduce oxygen pickup and foaming.
  6. As your beer gets close to the top lower the growler to withdraw the tubing and top up.
  7. Cap on foam.  When you cap on foam the head space is essentially purged with CO2.  Have a clean towel or rag available to clean up the excess and any spills.

Growler Fillers: These allow you to easily attach a length of tubing to your faucet for the purpose of filling a growler.  They can just as easily be used to fill a small kegging system or small keg.  Just use a longer piece of tubing.

Tapcooler & Nukatap Counter Pressure Fillers!

Looking for an easy way to bottle from your forward sealing faucet?  The Tapcooler and Nukatap Counter Pressure Bottle Fillers allow you to easily counter pressure fill bottles from compatible forward sealing faucets without a lot of tubing and cleanup. You can also use these without pressure to larger vessels like growlers.

Techniques and equipment for dispensing full corny kegs of beer

Now we transition into solutions for serving full 5 gallon corny kegs of beer.  Combine your keg full of homebrew with some sort of faucet and a CO2 source.

Quick Disconnect Faucet Assemblies:
These are nice because they generally look and work great and take up minimal space.

Make Your Own!  

Converters and QDs are available that allow you to connect your compatible faucet to a keg QD.

Other Faucet Options:

Flow Control Beer Gun FaucetFlow Control Faucet via Keg Connection.  This handheld faucet has built in flow control.  Variable flow control means you can change the resistance that this faucet provides.  That’s great for high carbonation beers and it also means less tubing.

Draft Jockey Boxes: These are for serving beer that isn’t necessarily cold yet.  Ice in the cooler gets beer down to serving temperature quickly.

A New Electric Jockey Box Option…

Since this post was written MoreBeer has released KRYO Inline Beer Chillers. These allow you to serve draft beer without a kegerator. The Nomad model is portable and essentially functions as an electric jockey box.

CO2/Pressure Options:

Now that we have a faucet that works on the go, we need some sort of pressurization system.  Of course you could lug around your full size CO2 tank and regulator, but this section focuses on options that are easy to transport.

There are two main types of solutions are mini/micro regulators and hand held injectors.  Mini regulators generally have the ability to maintain a set pressure vs injectors have no such control.  If you go with the generally less expensive injector option, I recommend running the thing yourself.  Guests tend to squeeze it for fun and sport and empty out the cartridge in short order.  You just need a couple of taps to keep the pressure at an acceptable level for serving.

Coolers and Ice Packs:

Sometimes you just want to throw some beer or a growler into a cooler.

Lots of different models of coolers out there.  See Amazon Best Sellers in Camping Coolers for current popular models

Cooler Shock Gel Packs – In my opinion… these are amazing.  The are made of thick mylar and come in several sizes and configurations.  Some are pre-made and others are DIY.  For the DIY versions you add the water to finish them off.


If you don’t filter your beer and decide to strap your keg on the back of an ATV and take off, you’ll soon figure out why people filter their beer as your guests remark at how Budweiser doesn’t have the same chunks of yeast that your beer has. 🙂


  1. Get it in place ahead of time and let it settle.
  2. Filter it.  Hands on Review
  3. Transfer clear beer to a new keg and leave yeast and trub behind.
  4. A tool that can be helpful for serving clear beer is the Top Draw Beer Pick Up Tube from William’s Brewing.  That pick up tube features a float and draws beer off the top of your keg.  That means anything that has been stirred up at the bottom of the keg remains at the bottom of the keg and gives it some additional time to settle.
