I'm dry hopping an ipa in the secondary now, (day 4). Primary lasted 2 weeks. The thing is there's been constant little bubbles rising for over a day now, forming a lil bit of foam on top. I've heard it's nucleation from the hops or the small increase in fermentation temperature causing the release of c02. I've instated a rise in temp from 68 up to 72. I was worried cause there's been a lot of them and theyve been constant for a while now. Fg after primary was 1.010, so I dont want it to go lower. Any feedback appreciated, thanks.
