I have another question about my first brewing/kegging experience. I think I over carved. hBS owner said I could take gas off, shake beer and then vent keg. He said continue to do this until I no longer have any co2 coming out when I vent. So I started this process, shook keg, vented, shook keg, vented, shook keg, vented and foam started spraying out of the release valve. Seems to be doing what it should. Any thoughts or help would be great. I burst carved on Monday, took it off the gas on Wednesday because I had only foam. Tried again Friday and only foam. Same thing today. Someone please help me get this beer drinkable.
