I'm going to try more dry hops for this next IPA. Should make it last longer. It could actually be from one of two things:
1. Cold crash. I turned on the cold crash after just a few days of dry hopping. Maybe cold temperatures slow the effects of dry hopping?
2. Gelatin. First time using it was on this batch of IPA. Maybe some of the dry hop goodness got sucked down to the bottom of my fermenter with the gelatin?
Oh well, it's still a fine IPA.
