I had my twin corny-keg setup in the garage in a refrigerator. The fridge kept it about 34 F degrees all summer, and I had the CO2 dialed just right.
Well, it dropped down to about -5 F and my beer froze inside the refrigerator. (Not solid - but it turned "slushy")
I brought the keg inside, and it's at about 43 degrees now. When I try to pour a beer all I get is foam.
Is this just because it's too warm now? Or did freezing it affect the beer (and it's CO2 absorption) in a bad way?
Is there a way to fix this, and get my keg flowing again?
