I have had a low ABV Neipa in the fermenter for 8 days now and there is a thick "cake batter" looking layer still on the top. It fermented hard for 3 or 4 days, I dry hopped on day 3. I plan to dry hop again today but I'm concerned with that layer on top. FG is within .002 of my expected FG. Anyone have this happen with this yeast?
