The word ‘vinegar’ comes from the Old French ‘vinaigre’, meaning sour wine. While wine can be sour, this particular taste profile is associated with spoiled food, and that is how vinegar came to be – through an accident. The sour wine eventually became one of the most widely used substances in human history, moving from Roman army canteens and medieval plague cures to the balsamic on your charcuterie board.
Vinegar was never invented; it was an accidental result of winemaking gone awry, like how Professor Utonium was trying to create ‘perfect little girls’ with sugar, spice and everything nice, but created superheroes instead. The first batches of vinegar were almost certainly the result of errors in winemaking, when grape juice fermented at too high a temperature, the bacteria overwhelmed the yeast, and the wine turned sour.
The Babylonians, around 5000 BC, were the first to record using it as a preservative and condiment, and they were also the first to flavour it with herbs and spices. Then comes date vinegar, which appears to have the oldest written records of all: made from pressed date syrup or date palm sap, it was widely used in the hot climate as both a cooking ingredient and a preservative. But where did it all begin?
Before it was something you cooked with, it was something people drank. The most common drink in ancient Greece was called ‘oxycrat’, which was a mixture of water, vinegar, and honey, kept in special vases called oxydes. Romans drank ‘posca’, a mix of water and vinegar sold in the streets, and a bowl of vinegar called an ‘acetabulum’ was always present at Roman banquets for soaking bread. Roman soldiers carried it on campaigns, and it was known as ‘poor man's wine’ (posca). The Bible records soldiers offering it to Christ at the Crucifixion.
Hippocrates gushed about its medicinal qualities, and it was likely one of the earliest remedies in use. Its applications also ran wide. Biblical references show how it was used for soothing and healing, and during the American Civil War, vinegar was used to treat scurvy. As recently as World War I, it was still being applied to treat wounds.
Then there's the more colourful end of the record, where a legend from plague-era France holds that four thieves robbed the houses of victims without getting infected, claiming their protection came from garlic soaked in soured red wine. Variants of the recipe, called Four Thieves Vinegar, have been passed down for centuries and remain part of New Orleans hoodoo tradition.
During the Zhou Dynasty (1046-256 BC), many royal and noble Chinese households employed a dedicated Vinegar Maker as a specialised position. The bulk of production was centred around what is now Shanxi province near the city of Taiyuan, a region that remains a famous vinegar-making area even today, with its culinary and medicinal uses recorded in the agricultural manual Qimin Yaoshu. In Japan, vinegar production was industrialised at the end of the Tokugawa Shogunate (1600–1868), which helped supply the growing demand for vinegar in sushi making.
Between the 5th and 15th centuries, vinegar-making spread across Europe, with the French city of Orléans becoming particularly famous for its quality. Their fermentation and ageing method became known as the Orléans process. By the Renaissance, vinegar-making was a profitable industry in France, producing close to 150 flavoured varieties. Meanwhile, balsamic vinegar began its evolution in the Duchy of Modena in Italy – a slow-aged product made from grape must that would eventually become one of the most recognisable vinegars in the world. It wouldn't become widely known outside Italy until the Napoleonic Wars, when French troops sold it abroad. England, separately, was developing malt vinegar – first known as ‘alegar’, made from malted barley.
The first large-scale industrial process for vinegar production was invented by Karl Sebastian Schüzenbach in the Kingdom of Baden in 1823. Called a packed generator, it circulated alcohol over beechwood shavings, cutting fermentation times from several months down to one to two weeks. This process also made spirit vinegar – distilled white vinegar – commercially viable for the first time. Louis Pasteur's (the same man behind pasteurisation) 1858 work, Etudes sur le Vinaigre, was the first to explain the microbiological basis of how vinegar is made, giving producers the science to back what they had been doing by instinct for millennia.
The 20th century brought another revolution with the submerged fermentation process, which cut production times down to just one to two days and allowed for mass production of affordable vinegar worldwide. Today, vinegar is produced from dozens of sources like molasses, dates, sorghum, fruits, berries, coconut, honey, beer, maple syrup, malt, and whey, among them, though the underlying chemistry hasn't changed since a Babylonian cask of dates first turned.
The origin of vinegar and its journey is unusually clean for a 7,000-year-old ingredient. It was an accident, then a drink, then a medicine, then a preservative, then a condiment, and finally, an industry. Each phase added a use without erasing the last. The US FDA now requires any product labelled ‘vinegar’ to contain at least 4% acidity, quite ironic given how vinegar started with a cask of wine that someone forgot about.
