<<Disclaimer: Verify this information before applying it to your situation.>> Can I correct one misunderstanding. Wine vinegar is made from wine. If it isn't, then it is not wine vinegar. I make it at home in a crock, using cheap wine purchased on booze-runs to France, odds and ends of home made wine, and occasional wine slops. A bacterium Acetobacter sp is used to ferment the wine in the presence of oxygen, the process takes a few months in the rather inefficient method we use, commercially the process is much faster. While I accept that the US food industry takes great liberties with its labelling (as often demonstrated on this list) I believe that any attempt to call "flavoured distilled vinegar" "wine vinegar" would breach international agreements.
