I have two Ales going right now.
An Imperial IPA (US-05) and an Alt (1007). Both are fermenting in my basement at 54.5F (wort temp).
What can I expect from the colder fermentation? Just longer ferment time? Sulfur (I don't smell any)?
Would it be better if I invest in a couple of fish aquarium heaters for my swamp coolers? My basement could still get a little colder as the winter progresses.
I also plan on doing a Kolsch.
