I've been making wine for about 4 years and have never seen this before. I bought some must a few days ago. I put 5 gallons of Zinfandel in a well sanitized 6 gallon carboy and added 5 crushed camden tabs. A day later I pitched some Montrachet and activity started within few hours. Everything looked good until this morning.
Now I see what I think are several small mold colonies on the inside of the glass in the head space of the carboy (several others started the same day look fine). What should I do? Should I transfer to another carboy, add camden again to kill sterilize again, and pitch new yeast? Or should I just relax and have a glass of Apfelwein?
