Well i added a second keg to my keggerator, so I turned down the temp in the fridge since i'm force carbing and the CO2 goes into solution better the colder the beer is. a day later i went to pour off of the first keg that was in there and nothing happened. I picked up the keg to make sure it wasnt kicked and i heard the sloshing of ice. I turned down the fridge and am waiting for the ice to thaw out, is there any danger to the beer and its flavor if it has frozen?
