I'm getting ready to do my second batch of beer (first all grain). I bought a mini fridge as my fermenter. Instead of shelling out cash for a thermostat regulator, I just put it on the minimum setting and I'm getting accurate readings of 55-59 F. I want to make either a Hefeweizen or a Blue Moon clone. Besides having a cleaner finish, what other effects will I have if I use lager yeast to make an ale?
