Vinegar has an almost indefinite shelf life when it is stored properly. Vinegar is self-preserving due to its acid content and does not expire. While vinegar may change color or develop a haze over time, it is still good and can still be consumed.
Vinegar with added ingredients, such as fruit, may need to be replaced after several years because its flavor can change. The best way to store vinegar is in a cool, dry place, such as a cabinet or pantry. Vinegar should also be kept in its original container with the lid tightly closed. Vinegar does not need to be refrigerated.
