make wine vinegar

one part unpasteurized vinegar and two parts red wine to a large glass jar. For my batch of red wine vinegar, I mixed one cup Bragg Organic Raw Apple Cider Vinegar with two cups Cabernet-Shiraz red wine.

I covered the jar with a piece of cheesecloth and secured it with a rubber band to hold the cloth in place. The jar was left in a warm spot for several weeks and I stirred occasionally during that time.

Then I added enough red wine to the jar, so that it doubled in volume, re-covered with the cheesecloth and let sit for another 3 weeks. This yielded 4 cups of red wine vinegar.
