How long does white vinegar last in the fridge?

Does White Vinegar Go Bad?

If you have ever found an old bottle in the back of your pantry and wondered if it is still safe to use, you will be glad to know the answer is a resounding yes. Vinegar has a virtually indefinite shelf life, meaning it never truly expires or goes bad.

The secret behind its incredible longevity lies in its natural acidity. Because vinegar is naturally quite acidic—usually containing at least four percent acetic acid—it creates an environment where bacteria and mold simply cannot survive. This natural preservation property means you do not even need to store it in the fridge; a cool, dark cupboard is more than enough to keep it stable for years.

You might notice minor changes over a long period, such as slight sediment settling at the bottom or a minor shift in color, especially with apple cider or specialty kinds of vinegar. However, these changes are entirely harmless and do not affect the quality of the product. Whether you are using it for cooking, baking, or cleaning your home, that bottle on your shelf is safe to use indefinitely.
