A little reason to celebrate
National Vinegar Day
Food · November 1
A look at vinegar, the sour pantry staple made by fermenting alcohol, and the many ways cooks use it in dressings, pickles and sauces.
National Vinegar Day falls on Sunday, November 1, 2026. That is 5 days away.
Vinegar starts as something else. Wine, cider, rice wine or malted grain is left to ferment a second time, and bacteria turn its alcohol into acetic acid. That acid gives vinegar its sharp smell and its sour bite.
The kinds taste remarkably different. Apple cider vinegar is fruity and a little rough. Rice vinegar is mild and slightly sweet. Red wine vinegar has some backbone, and balsamic vinegar, made from grapes, can be dark and syrupy. Plain distilled white vinegar is the blunt one, used as often for cleaning as for cooking.
In the kitchen, a splash of vinegar does what salt does in a different direction. It wakes up a flat soup, cuts through rich food and balances sweetness. It is the base of most vinaigrettes and the reason quick pickles taste like pickles. Many barbecue sauces lean on it, and in parts of the Carolinas the sauce is mostly vinegar and pepper.
A good way to learn the differences is a small tasting. Pour a little of each kind you own onto a spoon or a piece of bread and compare. You will probably find one bottle you reach for and another that has been sitting in the back of the cupboard for a long time.
That cupboard bottle is usually fine. Vinegar keeps well, though some develop a cloudy layer called a mother, which is harmless and can be strained out.
Ways to celebrate
- Make a simple vinaigrette with oil, vinegar, mustard and salt.
- Quick pickle sliced cucumbers or onions and keep them refrigerated.
- Taste two or three vinegars side by side on bread.
- Add a splash of vinegar to a soup or stew before serving.
- Try a vinegar-based barbecue sauce on cooked pork or chicken.
