Is vinegar an acid or a base?

Vinegar is an acid. White vinegar is mostly acetic acid and water. Wine vinegars are made by the acid fermentation of wine, while malt vinegar is made from malt liquor and cider vinegar from cider.

Balsamic vinegar is a prized and complex vinegar which is made from the must of Trebbiano grapes. The best types of balsamic vinegar are aged and enjoyed very much like fine wines. Balsamic vinegar contains no balsam. The name comes from Latin and Greek words that mean "restorative."

Vinegar can be flavored with nearly every sort of herb, including tarragon, basil, thyme, dill and mint.
