So, we just acquired a brew fridge from a neighbor, and used it for the first time this weekend for a batch of Dunkelweizen we brewed. Pitched the yeast last night when the stick-on thermometer read 56, and put a fridge thermometer in there. Went out this morning and the wort was frozen solid, thermometer read 32 degrees. Are we screwed, or can we pitch more yeast once it thaws?
