I'm curious if anyone has a suggestion for this one. I have a 2 tap kegerator. My beer lines are only 5', so I know I should go longer probably, but in the meantime, I'm a little confused by something. I have 2 beers on tap right now, both commercially filled corny's from the same brewery. One is dispensing very well, only a little extra foam in the first glass, but not bad at all. The other beer is dispensing with a *lot* of extra foam in the first glass. The keg's have been on tap for about a month now, so I'd think that even if they were carb'ed with different volumes of CO2 by the brewery, they'd have stabilized by now to my dispensing pressure of 10 psi. Any idea what else I should be looking at, for why one is coming out much much foamier than the other?
