How Is Vinegar Made
Vinegar can be made from any liquid that is capable of being converted into alcohol in a two-step process. The fruit juice or other liquid contains sugar, which is converted into alcohol and gas by the actions of enzymes. The alcohol thus formed combines with atmospheric oxygen by the action of Acetobacter bacteria, forming acetic acid. Organic acids and esters derived from the fruit or other source material are also present and are responsible for the flavour and aroma variations of vinegar. Table vinegar contains approximately 4 percent acetic acid.In 1864 the French physicist showed that it is Acetobacter bacteria that cause the conversion of alcohol to acetic acid. These bacteria work together symbiotically, producing enough acetic acid to prevent invasion by other organisms. Despite its ancient origin, the technology of vinegar production advanced slowly, improvements consisting principally of better methods of aeration.
The Orleans process, best-known of the old methods, used a barrel of about 50 gallons (200 l) capacity. A mash consisting of wine or other alcoholic liquid was poured into the barrel, and a small amount of vinegar containing a mass of vinegar bacteria, called mother of vinegar, was added to start the reaction. One or two small air holes drilled above the liquid level exposed the surface to.

The finished vinegar was drawn off through a wooden spigot near the bottom. Care was taken in refilling the barrel with the new charge of raw ingredients to avoid breaking up the surface film of bacteria. Cracker barrel rocking chairs replacement parts and accessories. Vinegar’s principal uses are the of foods and the preservation, or pickling, of meat products, fish, fruit, and vegetables. For use as a condiment, vinegar is often flavoured with, onions, or other herbs and spices.
How To Make Vinegar
Mixed with oil and seasonings it becomes a classic cold sauce— vinaigrette—used as a dressing on vegetable salads and served as a sauce with cold cooked vegetables, meats, and fish. Vinegar is also a common ingredient in marinades and is widely used in the pickling of and other vegetables. This article was most recently revised and updated by, Copy Editor.
