Vinegar

Vinegar (from Old French vyn egre 'sour wine') is an aqueous solution of acetic acid and trace compounds that may include flavorings. Vinegar typically contains from 5% to 18% acetic acid by volume.^[1] Usually, the acetic acid is produced by a double fermentation, converting simple sugars to ethanol using yeast and ethanol to acetic acid using acetic acid bacteria.^[2] Many types of vinegar are made, depending on source materials. The product is now mainly used in the culinary arts as a flavorful, acidic cooking ingredient or in pickling. Various types are used as condiments or garnishes, including balsamic vinegar and malt vinegar.

As the most easily manufactured mild acid, it has a wide variety of industrial and domestic uses, including functioning as a household cleaner.^[3]
