I brewed a black IPA three days ago and started seeing lots of action in my blow off tube this morning. I keep my primary in the basement shower as it maintains a steady 67 degrees with the door shut. Tonight, the whole bathroom kinda smells like eggs/ sulfur. I don't want to open the lid as I am sure I won't be able to "See" whats wrong. I don't want to say the words, but could I have an "infection"? and is there a magical penicillin shot I can give my beer, or is to late?
