So this is my first batch and I don't know if i was just too hasty and messed up. My primary had stopped bubbling (8 days in). I took a final gravity and it checked out to what it should be. I wanted to dry hop it in a carboy so I put the hops in the carboy and racked it. As I was racking I still saw tiny bubbles still coming up from the bottom though. Also when I opened the primary, the smell was kinda sour... is that bad? Is my batch infected? The color looked good...
