Since ancient times, people from all over the world have let wild acetic-acid bacteria turn their alcoholic beverages to vinegar. Each with its distinctive flavor, aroma, and color, naturally-brewed vinegars are derived from sugar cane, molasses, fruit, or grain. All vinegars share a mouth-puckering acidity that refreshes tired taste buds and stimulates the appetite. Vinegar is a vital food preservative, and plays an important roles in such products as health and beauty aids, antiseptics, cleaning solutions, and medicines.
