Bottling from keg problems

I use a blichmann beer gun to bottle from my kegs. I am having problems with large amounts of air in the 10’ foot line. Today I tried to bottle three different beers, the first two worked perfectly. The third has massive amounts of air in the line, and I can’t figure out where my problem is. In my mind it has to be the keg, because the other two beers bottled fine. Anyone had a similar problem, and able figure this out?

Could be co2 coming out of long between bottles? Just bleed off a little beer in a glass before you fill the bottle.

Keep the pressure on the keg and keep the beer lines cold (the first beer to come out may foam, but then it chills the line so it should get better) and fill slowly.

+1 to keeping the line cold. I always push a little cold beer through the line first and then let it sit in the kegerator while I sanitize bottles. I drop pressure in the keg to about 5 and clear the line of bubbles that form right before I start filing. Do you have issues serving from this particular keg?

I’m pretty sure it’s Co2 coming out of suspension, but not sure why. I was bottling in the garage which is about 10F, so the the line was plenty cold. I also try to clear the line, and then go straight to a bottle but it still wouldn’t work. I replaced all of my seals and put a cobra tap on and still not working. I guess I will mark the keg and keep notes on this to try and figure it out. :frowning:

Is the 3rd beer overcarbed?

Dang, what is the temp outside the garage?

If your beer is 10f there is a chance it got overcarbed. All of them would be overcarbed though unless the problem keg only has a little left it in it and has been cold longer than the other two.

I got a little sloppy / lazy with my keg cleaning procedures a while back and had some kegs which were an absolute PITA to get into bottles. Turns out, my beer was overcarbed from being ever so slightly infected. People were also having troubles pouring a perfect pint from my 10’ beer lines at 10-11 psi. To remedy it, I went through all kegs, disassembled and deep cleaned then. The dip tubes had beer stone on them and it was difficult to get it cleaned off. Now the beers pour very well and bottling from the tap is a breeze.

I’ve had issues with slightly foamy pours for beers that were dryhopped with pellets (in a nylon bag) in the keg. A bit of pellet gets stuck in the out poppet and it foams more than it should.

How does the temperature of the bottle and the beergun affect foaming when bottling with a beergun? How much would it help to chill them before use?

This is NOT what I would expect from your perfectionist ways! :stuck_out_tongue: Glad you got it all sorted out.

One of the factors that causes CO2 to come out of a solution is temperature. The more warmer things the beer touches, the more CO2 is coaxed out of the beer (hence foam). Its definitely tough to chill the beer gun, once it is assembled and sanitized, but as long as you keep the keg and bottles chilled until the last possible minute.

If you are like me and bottling multiple beers/multiple kegs during a bottling run, It doesn’t hurt to put the kegs in a tub of ice water during the run. That way you don’t have to worry about beer warming up and you can just switch connections quickly during the run.
