I brewed a batch of dead guy and pitched US-05 for 7 days at 65F. On day 6 the temperature outside dropped to the mid forties and because of that the freezer that I use as a fermentation chamber dropped to below the set point of 65F. When I opened the freezer yesterday morning, the temp was 58 and there was a cheesy yeasty foam inside and coming out of the airlock. Is this a problem? What is it?
