So I started a batch of mead on saturday with Wyeast Sweet Mead. It's been 72 hours with no visible activity in the airlock. So I took another hydrometer reading. It started at 1.120 and is down to 1.110. I know the Wyeast is supposed to be slow but at this rate it'll take 30 days to get fermentation down to acceptable levels. Does this sound right to anyone else?
