Since lemon juice is also acidic, you may wonder does lemon juice go bad, too? Yes, lemon juice can spoil, as well. The second reason the acidity level of the vinegar may decrease is due to the decomposition of the acetic acid over a period. The dilution of the product causes a reduction in the acidity of the vinegar. First, water is absorbed into the vinegar over a period, diluting the concentration. Once you’ve passed the expiration date listed on your container of vinegar, one of two things happens to cause the acidity level to decrease. While vinegar will not go bad, its acidity level will change over time. This can be a bit confusing, since, according to a study conducted by the Vinegar Institute, the shelf life of vinegar is indefinite.

The “mother of vinegar” is the original bacterial culture that is used to begin the fermentation process of the ethanol. You can measure the pH of vinegar with a pH strip, which you can find online or at your local drug store. However, the commercial distilled variety that is available at any grocery store has a pH of between 2.40 and 3.40. The specific pH of vinegar varies, depending on how much acid it contains. You can even make apple cider vinegar or white vinegar yourself. It can be created using a variety of different ingredients that lend to each type of unique qualities and flavors. The acetic acid is what makes vinegar unique.Īlong with the acetic acid, vinegar contains other substances like minerals, vitamins, and other flavor compounds. Bacteria are used to break down, or ferment, the ethanol into several byproducts, one of which is acetic acid. The acidic liquid is created through the fermentation of ethanol alcohol.
