Good brew day yesterday. We worked out most of the kinks in the new system. Pumped 11 gallons of O'fest into the Freezementer. That's right, NO MORE CARBOY LIFTING! I put on freezer on wheels....best brew gadget to date. Anyway, I noticed last night that both airlocks got some water sucked back into the fermenters. Not sure why? Too cold? This never happened in my old fridge. Should I just leave the airlocks (3 piece) dry until fermentation starts or until it's almost complete for that matter?
