I am newer to brewing and I have attempted to brew a lager. I have a Bohemian lager in a min fridge at home. I placed it in on Sunday and by Tuesday the fridge temp had dropped to 25 degrees Ferenhit. I was able to catch it before the beer itself frooze but the water in my airlock did freeze. My question is this, is the batch ruined? Would the temp kill the yeast?
