I have been kegging for a good while now and have had maybe 30 kegs in the keezer, all sit on the co2 for over a week (11psi @ 38ish degrees) before I start drinking and all turn out great... no issues except for my xmas ale. It's all foam, if I turn off the gas and pull the pin for a little and serve it's fine. Eventually it goes to a trickle and I turn it back on for a little and serve again. Everything else in the keezer is fine. It hasn't been out of the keezer since I put it in and hasn't been moved? The last time I did the recipe it turned out fine. Anyone else had an issue with just one beer not carbing right?
