OK, I am too excited to start new brews that I am moving my first brew to second stage after 10 days. Then I will let it sit for 7 more days then 2-3 weeks in bottles. My second brew will sit for 12 days in primary stage, just by timing of buckets. I am following BEV ART recommendations. I have a new issue with my second brew. It was brewed on 4/26. My first brew was bubbling in the air lock at 24 hours, this one has not bubbled through the air lock yet. If I push on the lid it bubbles. I opened the bucket and there is a ring about a half inch above the liquid, my first brew was an inch above the liquid. My second brew has a layer, very thin, on top with active bubbles. I am worried that since I am not having bubbling in the air lock then there is a fermentation issue. To me it has a slight rotten egg smell but I am over thinking and smelling everything. Any help is appreciated. By the way it is a Witbier
