The word vinegar comes from what french meaning?

It comes from the French "vinaigre", which is the two Words "vin" (wine) and "aigre" (sour) put together.

The preferred vinegar for French dressing is naturally aged red wine vinegar. Most vinegars are now aged industrially artificially in just a few hours instead of a few weeks, so they taste more like acetic acid than real vinegar.

Growing your own vinegar with a "mother" of vinegar is a fantastic experience to comprehend that French meaning...
