I have a question. This particular brew is a white IPA and brew day was a week ago. I had a violent fermentation the first night after brewing to where a lot of krausen built up, expanded the bucket outwards and spewed a little wort through the airlock. I added ferm cap and resealed the fermenter. It has been fine ever since and krausen has subsided. Gravity dropped to almost FG after just 3 days.
I checked the gravity levels after a few days and noticed a build up around the inside of the fermenting bucket rim near the top. The build up is greenish in color and kind of "gunky" looking. Ironically enough, I also got this same build up in my kettle during game the boil right after I added in the Hops.
Would anyone happen to know of this is normal and what it might be?
I've tried to add a pic, but it's not letting me...maybe size is too big.
Thanks for any help!
