i quick carbed a few kegs for a party, one was overcarbed and didnt kick, if i set it to 10psi in my kegerator will it eventually return to a normal carb level?
If the beer is very foamy, turn the air off to it, vent the keg, the CO2 will come of the beer over time, repeat until you have it at the proper level you want and then turn the air back on. I had this happen with a wheat beer that I forgot to turn down the CO2 after a couple days. I was burping every night for about a week to get it down to the a good carb level.
