Will Balsamic Vinegar Go Bad If Not Refrigerated?
Balsamic vinegar does not need to be refrigerated, but it will last longer if it is. If left at room temperature, the vinegar may start to degrade after a few months or develop a slightly different taste, but it will not necessarily go bad. To maximize its shelf life and maintain its flavor, it is best to store balsamic vinegar in a cool, dark place, such as a pantry or cupboard.
