I brewed a batch of Belgian strong ale a few weeks ago and it seemed my fermentation got stuck. I did all the tricks to it going again...ended up adding some champagne yeast. Nothing seemed to work as I had no activity through air lock after a week (stainless conical so I can't see it). So I racked it off to the secondary and added my dry hops. While cleaning the primary there was ALOT of foam, yeast clumps etc. I just looked at the batch now (week or so later) and although there is no activity through airlock it's got alot of foam on top....did the champagne yeast finally kick in or did the dry hops add some nasties that are having a party in my beer?
