Fermentation has drastically slowed on Yeti. Brewfather’s graph shows a distinct flattening of the gravity curve just below expected FG, and the chiller’s cooling cycles have elongated and now stopped in response to a drop in yeast activity.
This isn’t unusual in and of itself, but I don’t think I’ve seen it just three and a half days after starting primary fermentation. The successful starter probably had a lot to do with it, so I’m going to flag this as #wisdom and will repeat the recipe (especially the timings) next time around. The only question now is whether I let it ride the full 2 weeks (and cold crash from 2-5 December while we’re away) or do I try to crash for a day and keg it early?
