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 carbon dioxide gas by the actions of yeast enzymes. The alcohol thus formed combines with atmospheric oxygen by the action of Acetobacter bacteria, forming acetic acid and water. 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.
