Default What to do about Flat Beer

I've had my Dunkleweizen Kegged for a few weeks -- it pours with a nice head, but the beer is still flat.

Serving psi is at 12.

Any ideas/suggestions?

Thanks,

Rick

Just wanted to also mention I am new to kegging.

Basically I "set it and forget it" at 12psi -- did not shake or roll keg intially or did not set to a higher (e.g. 30psi) intially.

How much priming sugar did you add to keg?

Hmmm. It should be pretty well carbed by now. You could try turning the gas up to 14-15 psi and see how that is in a few days. What is the temperature of the kegerator?

Another thought I have is sort of a long short. Do you have short (under 6') beerlines? Sometimes with a short line, the beer comes out a little foamy and the top has a nice head but the beer is seemingly flat because the co2 comes out of suspension and makes a head but then the beer doesn't have enough co2 in the beer.

Thanks for the response Yooper.

Yes I did crank up to 15psi for a few days and just tried it last night. More foam and still flat.
The fridge is at 45f.
The beer tastes really good -- just flat as hell.

My beer line is 5ft. I don't have my tower tap installed yet-- so I'm just using the picnic tap dispenser right now.

What length beer line seems to work the best?
6ft?

Thanks. Rick

Have you checked for leaks around the gas in post and lid?

None -- I am strictly force carbonating it.

I'd say the problem is the short beer line for the amount of carbonation you have. AT 15 psi, at at 45 degrees, you should be at 2.5 volumes of Co2- about perfect. I'd change right away to 10' of 3/16" beverage line and I think your problem will be solved.

Ok sounds good -- I'll check for leaks first and if no leaks. I'll buy 10 ft of 3/16" line.

I'll keep u posted-- thanks.
