Vinegar
Sour wine turned into a versatile culinary and industrial staple.
Vinegar is an odorous aqueous solution of diluted acetic acid and trace compounds, typically containing from 4% to 18% acetic acid by volume. It is produced by a double fermentation process—converting simple sugars to ethanol using yeast, then ethanol to acetic acid using acetic acid bacteria. Vinegar has been used since ancient times for culinary, medicinal, and industrial purposes, and remains a staple in households and cuisines worldwide.

Lore & Background
The word 'vinegar' arrived in Middle English from Old French 'vyn egre' (sour wine), which derives from Latin 'vīnum' (wine) and 'ācre' (sour). Traces have also been found in Egyptian urns. In East Asia, the Chinese began professionalizing vinegar production in the Zhou dynasty, with the book Zhou Li mentioning specialized 'vinegar makers' in noble households. Many Chinese vinegar types and uses were recorded in the agricultural manual Qimin Yaoshu.
Reader's Guide
Vinegar's significance spans millennia and cultures. The Greeks and Romans used vinegar made from wine; the Spartans added it to blood soup to prevent coagulation. In the late Middle Ages, the French city of Orléans became famous for its vinegar through the Orléans process, while malt vinegar (alegar) developed in England and balsamic vinegar evolved in the Duchy of Modena. Louis Pasteur discovered that acetic acid bacteria were the agent of fermentation. In the 20th century, submerged fermentation cut production to 1–2 days, enabling mass production of cheap vinegar worldwide. Today, vinegar is used in cooking, pickling, cleaning, and industry, with varieties ranging from fruit vinegars to palm vinegars and balsamic vinegar.
