I brewed this on 12/22, took a hydro reading today (1/13) and it went from 1.064 to 1.038. I guess I have a stuck fermentation? I've had the temp set at 64°. Should I just set the temp to say 72° and it will start up again?
I had made a few small changes to this recipe. I added a 1lb of light brown sugar and used 1 1/2lbs of lactose instead of 1lb. Fermentation got off to a great start, was vigorous and lasted 3-4 days.
