I’m fairly new to kegging. In fact, I’m only on my third keg. I’ve got all three hooked up and under about 8 PSI with 6 feet of 3/16 tubing on each. Temp is around 40 F. I’m getting tons of foam from my IPA, but not my porter or brown. After a few pulls, it usually dies down. None of them are over carbed.
What am I doing wrong?
