Beer Gun on the Cheap


IMG_1632If you are like most home brewers, it won’t take long for you to come to the conclusion that bottling your beer is kind of a pain. You have to wash all those bottles, sanitize them, measure and boil your priming sugar, and transfer your beer to the bottling bucket. Then, once you finally have all those bottles filled and capped, you get to clean all your gear and whatever mess you made in the process.

Fortunately, there is no homebrew problem that cannot be solved by throwing cash at it. So you start your internet shopping and Craigslist stalking and don’t stop until you have collected all the hardware necessary to keg your beer. Thing is, though, you are still probably going to want to bottle occasionally. Sure, growlers are a great way to transport and share your brews, but you can’t get away from bottles completely. Growlers will only keep beer fresh for a few days and if you decide to enter your beers in competitions, bottles are an absolute must.

The problem is, your kegged, carbonated beer is kind of a pain to bottle. Pouring a pint into a glass is no problem at all, but try to fill a bottle from your faucet or picnic tap and you’ll get a bottle mostly filled with foam. Enter the counter-pressure bottle filler. Blichmann, among others, manufacture off the shelf beer guns that will let you bottle your homebrew a bit more easily. A one hundred dollar bill and a little time to dial your pressure in and you are ready to bottle away.

If you are like me, though, and are inclined to keep that Ben Franklin in your pocket, there is a cheaper alternative. A little rummaging through your spare parts bin and maybe a trip to your local homebrew shop is all that stands between you and a very effective bottle filler.

A good first step when tackling any brewery related DIY is a visit to Homebrew Talk. The sum total of all of humanity’s homebrew knowledge can probably be found in this forum and a cheap bottling apparatus was just a click away. You can find the original post that I used as a reference here.

You really only need three things to build this bottler:

  • A picnic tap that fits your keg setup
  • A bottling wand
  • A stopper (with hole)
  • Teflon Tape (You may or may not need the tape depending on the size of the hole in your stopper and the diameter of your bottling wand.)

It turns out, the bottling wand can easily be inserted into the dispensing hole of the picnic tap. You will not need the spring loaded thingy that on the end of the bottling wand. Just pull it off and try not to lose it.

Once you have inserted the wand into the picnic tap, slide the stopper onto the wand and position it so that when the stopper seals the top of the bottle, the tip of the wand hovers inside the bottle, just above the bottom. The hole in my stopper was slightly too large and the stopper tried to slide around on the wand a bit. I ended up wrapping a few turns of teflon tape around the wand to hold it in place (I remove the tape and replace it each time I clean the wand after using.)



Once your gizmo is assembled, bottling is a very easy. The best practice is to use as little gas pressure as possible. Compare my methodology to the description given in the Homebrew Talk post and you’ll quickly find a method that works for you.

  • Start with sanitized bottles (Obviously. Cleanliness is next to Godliness and all that. Also, chilled bottles will foam less than warm ones.)
  • Turn off the gas supply and release the pressure in the keg with the quick release valve. Some folks will turn the pressure on their regulator down to 1 or 2 psi. I prefer to bleed off most of the pressure in the keg and use a bit of residual pressure to gently fill my bottles. If the flow gets too slow, I will give it a quick burst of gas, just enough to get the beer flowing again.
  • With the stopper sealed against the crown of the bottle, begin filling the bottle. As the bottle is filled with beer, the pressure in the bottle with build, keeping the carbonated beer from foaming, and the flow will slow and eventually stop. Lift the bottling wand ever so slightly and allow the pressure to “burp” out of the bottle. Re-seat the stopper back on the bottle and continue to fill. The flow will continue until the pressure builds up again. Keep burping and filling until the bottle is full to the crown.
  • Once the bottle is filled, lift the wand out and give it one final squirt if necessary to adjust the head space in the bottle. Cap with a sanitized cap and your preferred capper.

After using this setup on a number of occasions, filling bottles for competition and for Christmas gifts, I am pretty happy with it. I tasted a couple of test bottles (I’m sure you will appreciate that level of dedication) and was pleased to see that all samples were still properly carbonated. Until Blichmann decides to send me one of their Beer Gun to review, this cheap little number will be my bottler of choice.
