Hey first timer here. Doing Russ Whaley's apple pie spiced cyser. Pitched k1v three days ago. It's bubbling away really well but there is a weird foamy scum on top, can't seem to get a clear answer on if it's an infection or just the spices and particles ( it has the same color as the spice mix). It still smells good, sweet and appley with no sour notes. This is my first go so maybe I'm being paranoid. I sulfated with campden tablets for 24 hours before pitching and sanitized everything I used. Stuff on the side of carboy was from shaking it. Please tell me it's not ruined.
