does soy sauce expire?

Answer 1

Yes, it does and you may not know that it should be stored in the refrigerator after opening. It looks like something that would last forever, doesn't it? I found this info from Kikkoman:

When it comes to soy sauce, I received the following advice from the Consumer Department at Kikkoman. While the comments refer specifically to Kikkoman soy sauce, in general they should be applicable to other soy sauce brands:
"For the freshest tasting sauce, we recommend using Kikkoman Soy Sauce within three to six months after opening. The sauce is still safe to use beyond this time but the quality may not be at its best. Once opened, the freshness and flavor of the sauce will slowly deteriorate. Therefore, we also recommend refrigerating the soy sauce after opening. Refrigeration helps the flavor and quality characteristics remain at their peak for a longer period. In addition, our soy sauce will not spoil if it is not refrigerated but its quality will decline faster.

A fresh bottle of Kikkoman Soy Sauce should have a piquant flavor and reddish-brown color. When opened and exposed to air, naturally brewed soy sauce will darken and become stronger in flavor and aroma over time. This is the result of oxidation. Although this is not harmful in any way, it will cause the quality to decline. With an older bottle, the sauce may appear darker in color and have a strong, heavier taste. We believe the flavor of our soy sauce is at its peak when the bottle is first opened."
