How Long Does White Vinegar Last?

White vinegar has no meaningful expiration in a safety sense — its acidity creates an environment simply too hostile for the bacteria and mold responsible for most food spoilage to establish themselves, which is why it doesn't carry a genuine safety deadline the way almost every other ingredient on this site does.

A cloudy appearance or a harmless, jelly-like formation called "mother" (a cellulose byproduct of the fermentation process vinegar comes from) can develop in a bottle over a long stretch of time — a normal, safe occurrence rather than any sign of spoilage, and some people deliberately preserve vinegar mother to start a new batch of homemade vinegar.

Because there's no real safety countdown to track, storage guidance for white vinegar is really about protecting its exact flavor and potency rather than avoiding any hazard — keeping the bottle sealed and away from a hot stove or a sunny windowsill preserves its sharpness longer, though even a bottle stored less than ideally for years remains safe to use. A bottle purchased in bulk for cleaning purposes as well as cooking doesn't need to be split into separate containers or treated any differently based on intended use — the same indefinite shelf life and lack of any real spoilage risk applies whether the vinegar ends up in a marinade or a spray bottle for countertops.
