Ill piggyback on this old thread. I have been stuggling to get the foam to subside in my kegs. Ive kegged 5 batches, and all of them have foamed like crazy. My setup: 5ft 3/16 line, keg temp around 39-40 degrees. Set PSI to 30 for a day, then dial it back to 12psi for a few more. When i pour it at 12psi, i get huge globs of foam that come from the tap. So i try shutting off the gas, purging it and pouring it so slow that it barley comes from the tap, still giant globs of foam come out. I get about 90% foam in every glass, its not a line temp issue. I have pulled apart my kegs to check for any obstructions in the dip tube, poppets, etc. Is this an overcarbing issue or a balance issue? I could try switching to 10' lines, but the fact that it still foams when pouring at a trickle makes me think thats not the issue here. The beer does not seem overcarbed when drinking it, nor does it seem undercarbed. Im at a loss.
