I have a beer gun. I use two Co2 tanks set at around 5 psi, one for the keg and one for the gun. I have the darndest time getting a bottle full without a foamy overflow resulting in either too little or too much beer (right up to cap) per bottle and a lot that goes down the sink. Why is this?
Here is the process I use:
1 Get bottles as cold as the beer, even colder is OK.
2 Turn off gas to keg, bleed off head pressure in keg.
3 Turn CO2 tank regulator down to 2 psi.
4 Turn gas to keg back on.
5 Fill bottles.
The two things that I’ve found that make the most difference are: getting the bottles cold, and using the lowest psi that will move the beer from the keg to the bottle.
One more thing to add to the good advice above, get the beer gun and lines cold too. You can run cold beer through it, or to not waste beer I have put it in the freezer for a little while.
I also find that getting the bottle cold and rinsing it right before filling helps a lot.
5psi is pretty high, I go really low and take my time. +1 on Maine’s 2psi suggestion.
That all makes sense. Yes my bottles and lines are always room temp, and sometimes the psi is as high as 8. I thought that it should be at serving levels. Thanks. Will try this the next time.
I just bought the Blichman gun and I filled a bunch of growlers as suggested above I chilled everything down. Im finding that the carb levels are not holding up at the one month mark. Am i doing something wrong?
The growler screw on caps may leak. I have never kept a full growler more than a day or two.
Yeah, growlers are not meant to store beer for long term. The seals just are not good enough.
How about growlers that have the Grolsch style swing tops?
Cheers!
A little late on the reply, but you should make sure that whatever pressure you are serving at that the line you have attached it long enough to support that PSI.
