Health Benefits of Vinegar

The Healing History of Vinegar

Vinegar is a dilute solution of acetic acid that results from a two-step fermentation process. The first step is the fermentation of sugar into alcohol, usually by yeast. Any natural source of sugar can be used. For example, the sugar may be derived from the juice, or cider, of fruit (such as grapes, apples, raisins, or even coconuts); from a grain (such as barley or rice); from honey, molasses, or sugar cane; or even, in the case of certain distilled vinegars, from the cellulose in wood (such as beech).

The word "vinegar" comes from
the French word for "sour wine."

What you have at the end of this first phase, then, is an alcohol-containing liquid, such as wine (from grapes), beer (from barley), hard cider (from apples), or another fermented liquid. (The alcoholic liquid used to create a vinegar is generally reflected in the vinegar's name -- for example, red wine vinegar, white wine vinegar, malt vinegar, or cider vinegar.)

In the second phase of the vinegar-production process, certain naturally occurring bacteria known as acetobacters combine the alcohol-containing liquid with oxygen to form the acetic-acid solution we call vinegar. Acetic acid is what gives vinegar its sour taste. Although time-consuming, this second phase of the process will happen without human intervention if the alcoholic liquid is exposed to oxygen long enough.

Thus, it is not surprising that the first vinegar was the result of an ancient accident. Once upon a time, a keg of wine (presumably a poorly sealed one that allowed oxygen in) was stored too long, and when the would-be drinkers opened it, they found a sour liquid instead of wine. The name "vinegar" is derived from the French words for "sour wine."

Fortunately, our resourceful ancestors found ways to use the "bad" wine. They put it to work as a cure-all, a food preservative, and later, a flavor enhancer. It wasn't long before they figured out how to make vinegar on purpose, and producing it became one of the world's earliest commercial industries.

The use of vinegar as medicine probably started soon after it was discovered. Its healing virtues are extolled in records of the Babylonians, and the great Greek physician Hippocrates reportedly used it as an antibiotic. Ancient Greek doctors poured vinegar into wounds and over dressings as a disinfectant, and they gave concoctions of honey and vinegar to patients recovering from illness. In Asia, early samurai warriors believed vinegar to be a tonic that would increase their strength and vitality.

Vinegar continued to be used as a medicine in more recent times. During the Civil War and World War I, for example, military medics used vinegar to treat wounds. And folk traditions around the world still espoused vinegar for a wide variety of ailments. Natural-healing enthusiasts and vinegar fans continue to honor and use many of those folk remedies.

Early Wines and Vinegars

Scientists believe wine originated during the Neolithic period (approximately 8500 b.c. to 4000 b.c., when humans first began farming and crafting stone tools) in Egypt and the Middle East. Large pottery jugs dating back to 6000 b.c. that were unearthed in archeological digs possessed a strange yellow residue. Chemical analysis revealed the residue contained calcium tartrate, which is formed from tartaric acid, a substance that occurs naturally in large amounts only in grapes. So the traces strongly suggested the jugs were used to make or hold wine.

Considering the slow grape-pressing methods used at that time and the heat of the desert environment, grape juice would likely have fermented into wine quite quickly. Likewise, the wine would have turned to vinegar rapidly, if conditions were right.

So how did these ancient people -- who had only recently (in evolutionary terms) begun planting their own food and fashioning tools -- manage to understand and control fermentation enough to prevent all their wine from turning to vinegar before they could drink it? Based on evidence found in archeological excavations, scientists believe that the first winemakers used jars with clay stoppers that helped control the fermentation process.

A complete analysis of the residue left in those ancient wine jugs also showed the presence of terebinth tree resin, which acts as a natural preservative and therefore would have helped slow the transformation of wine into vinegar. In Neolithic times, terebinth trees grew in the same area as grapes, and their berries and resin were harvested at the same time of year. So it's quite plausible that some of the berries or resins may have inadvertently become mixed with the grape harvest. Still unclear is whether the ancient winemakers ever made the connection between the resins and the delayed conversion of wine into vinegar and began purposely adding the tree berries to their wine.
