If you’ve found a bottle of soy sauce that’s a few years old you’ve probably asked yourself the question “does soy sauce go bad?”. Fortunately for you, your soy sauce probably is fine. Soy sauce contains a ton of sodium, so it’s extremely difficult for any microorganism to develop and grow in that salty environment. The taste of soy sauce will, however, deteriorate over time. If the sauce will be stored properly it will retain its freshness and flavor for a longer period of time. As a side information, you should know that many kinds of soy sauce aren’t free of gluten, but there are some gluten free soy sauce brands.
How To Store Soy Sauce
While your bottle of soy sauce is unopened you should store it in a cool, dry area. The pantry seems to be the best place to store the unopened soy sauce. After the bottle is opened, you should store it either in the pantry or in the fridge. If you’ll store it in the refrigerator it will retain its taste for a longer period of time. Therefore, if you plan to utilize the whole bottle in a couple of months you can freely store it in the pantry. Please note that the bottle should be sealed tightly.

Shelf Life Of Soy Sauce
Even though soy sauce probably won’t go bad, it probably has a “best use by” or “best-by” date on its label. That date informs you how long the product should be at its best quality (according to the manufacturer’s data). That means that somewhere after that date the product will possibly start to lose its quality and its flavor won’t be as good as fresh product’s one. An unopened bottle of soy sauce should be fine for at least three years. After the bottle is opened, it should offer its best for about two years. This period of time depend of course on the producers and the quality of the product itself.
