How Do You Know If Red Wine Vinegar Has Gone Bad?
Red wine vinegar can go bad if it develops a strange odor, taste, or appearance. Signs of spoilage may include a murky or cloudy appearance, sedimentation, or changes in color. The vinegar may also emit a pungent aroma or taste sour or bitter. It is important to note that red wine vinegar has a longer shelf life compared to other types of vinegar, but if it has been stored improperly or is past its expiration date, it may go bad. It is best to store red wine vinegar in a cool, dark place, away from heat and sunlight.
