I believe that Acetobacter is the bacteria culture that turns wine and cider into vinegar. If so wouldn't it be better to take natural (non pasteurized) wine vinegar instead of wine?
I ordered a wine vinegar culture a few weeks ago and started fermenting. It takes 3 months and it isn't half finished yet. Before I stated the vinegar, I had to try a teaspoon of the wine vinegar culture. It was awesome! I hope my vinegar turns out this good.
