I brewed a SNPA clone two weeks ago and it still has a full head of krausen, I pitched at 72, it started up pretty typical, it's been hovering between 64 and 68 in my cold basement. Bubbles slowed down after a few days, but it's still slowly chugging.
I've never had this happen before, not sure what to do? Heck the beer is even clearing up quite nicely.
Thoughts???
Cheers
