An open bottle of soy sauce will last for up to a year. But you may start to notice the color fading and the taste dwindling after six months. Just because it doesn’t look or taste exactly as it did the day you bought it doesn’t mean it is bad.

Most often, oxidation will play a large role in your soy sauce’s condition. It will change the appearance, taste, and smell. This in itself is not dangerous. It just makes your dish taste less bold and savory. 

What can potentially become dangerous is bacteria and mold. These harmful agents can cause serious health problems if ingested. You risk the development of mold when the condiment isn’t correctly put away. 

What Causes Soy Sauce to Go Bad?

Most often, soy sauce goes bad due to improper storage. This item should be put into a cool, dark location. It should be fully sealed and preferably in a glass container. 

Heat, light, and oxygen exposure are the main culprits of spoiled soy sauce. So if you do decide to keep it on the countertop, make sure it is not in the path of direct light. 

If you believe your soy sauce is bad, toss it out right away. Signs of bad soy sauce include foul odor, odd texture, and extreme discoloration.
