Hi!
New here, really happy to have found this forum! I've fermented some stuff before, sourdough, sauerkraut, .. I'm trying to make hard apple cider with no added yeast now. After a few days, blue mold has appeared on top of it.. I could take it off easily and now praying it doesn't come back.
What should I do, toss it all out and start again, or just hang in there?
