Brewed my first attempt at several things. First black/brown double IPA, first double IPA, first time pitching on an existing yeast cake and my first experience w/ an OG over 1.100. Well decided to start fermentation at a cooler temp and left the Black Abyss in the garage. Glad I did. This was also my first experience with explosive fermentation. It blew the stopper and blowoff tube almost 5' away from Carboy. I hope this is a good sign.
