Hi all,
I wanted to make cider vinegar. I've successfully fermented cider before, but wanted to go straight to cider vinegar. I had a jug of juice that I'd pressed in fall and put into the freezer for a few months. I took it out, thawed it and poured it into a 1 gal glass jar, put a cloth over the lid, secured with a rubber band and left it on a shelf. I didn't look at it again for a week. When I peeked today, I noticed a bunch of circles of bright green mold floating on top of the liquid, plus a nice white fuzzy patch too. Not good, I assume. I guess I should have been stirring it?? I didn't sanitize my jug either, so perhaps there was some source of the mold in the jar.
I'm assuming that this batch is toast and I should pour it out and wait until I can get a good bunch of organic apples again next fall? Any other tips?
