I have a beer with a starting gravity of 1.094. Used two viles of WLP001 in a 1800ml starter. Fermentation took right off, slowed after about 6 days, but then seemed to pick back up a little bit.
My question is, what would cause it to slow and then pick back up? Temperature remained the same throughout the fermentation. I've only ever seen the activity go in one direction, from fast to slow. Not Fast to slow back to Medium Fast
