Dark soy sauce is best stored in a cool, dark place to maintain its flavor and quality.
When unopened, dark soy sauce, like other light-sensitive and temperature-sensitive products like olive oil and vinegar, benefits from being stored away from light and heat. Once opened, refrigeration is the optimal storage method to preserve its taste and prevent spoilage.
Here's a more detailed breakdown:
-
Unopened Bottles: Store in a pantry or cupboard, away from direct sunlight and heat sources (such as the stove or oven).
-
Opened Bottles: Refrigerate after opening. While soy sauce's high salt content makes it relatively shelf-stable, refrigeration helps to maintain its flavor and prevent it from oxidizing, which can diminish its quality over time.
In summary, store unopened dark soy sauce in a cool, dark place, and refrigerate it after opening to maintain its best flavor and quality.
