I am brewing a Hefeweizen today using the white labs hefeweizen yeast. My mini fridge wont go any higher than 57 degreees but if I turn it off it gets up to like 80 degrees. I know I can buy an external controller for the fridge but I havent made that investment yet. The question is what temp should I ferment this at? 57 or 80? I know neither is ideal but Im haveing a hard time making the decision on my own and need help from you guys.
