I brewed Saturday, normal day outside using my new grain mill (got a nice boost in my OG!). Added Yeast Nutrient at 10 minutes left of boil, used a normal pouch of Wyeast, broke the packet inside, it swelled (not as swelled as normal, but still as much a sometimes it does). Added the yeast then put it away. Day 3, there's no bubbles in the airlock, and my Tilt hydrometer is not reporting any change in the gravity.
I've never had this happen before! Is my beautiful IPA ruined? Where do I go from here?
