I'm trying to ferment apple cider vinegar. My friend made a bunch of crab apple jelly and I brought home a big sack of apple bits. It's been fermenting with water in a huge bucket for about 2 weeks. When do I strain out the apple bits? How long until it's vinegar? Should I add some Braggs to get it headed in the right direction? I have about 4 gallons. I would like to feed the apple bits to the chickens but not if they are still full of alcohol. It smells good and is very bubbly still.
