Soy Sauce Doesn’t Go In The Fridge
Soy sauce can live just fine in a pantry for up to a year and a half. It doesn’t need to be refrigerated because it’s fermented. The fermentation process both makes the sauce delicious and allows it to stay fresher for longer.
Keeping soy sauce for longer than a year and a half might change the flavor of the sauce a little bit, but it should still be good to eat.
