Hi there! Bear with me, this is my first try at making wine, and I have tried following my instructions as close as I can, but I checked my must after I added the rehydrated yeast about 20 hours ago, and there were no bubbles in the airlock, and something has formed at the top. There are a few bubbles in the formation, but I’m wondering if I’ve screwed this up already. Can anyone tell me if this is normal, and if not, is it fixable? Thanks!
