-
Store in a cool, dry place: Keep unopened sauce in a pantry or cupboard away from heat, moisture, and direct sunlight.
-
Buy smaller bottles: Once opened, sauce keeps longer in smaller containers with less air exposure. Or transfer to a smaller jar for storage.

Use clean utensils: Always use a clean spoon or spatula each time you access the sauce to prevent contamination. Never return a used utensil to the bottle.

Check before use: Give the sauce a quick visual inspection and sniff test before using to ensure it hasn’t spoiled.
How to Tell if Your Black Bean Sauce Has Gone Bad
Though unopened black bean sauce keeps for a remarkably long time, it will eventually degrade in quality and become unsafe to eat. Here’s how to identify when your sauce has gone bad:
-
Change in color: Fresh sauce is dark brown or black. Discoloration to grey, green, or yellow is a red flag.
-
Strange odor: Sauce that smells unpleasantly sour, rotten, or funky should be discarded.

Mold: Check carefully along the rim and seal for any fuzzy mold growth. Mold means the sauce must be thrown out.
-
Fermentation: Bubbles, fizzing, or increased gas inside the bottle are signs of unwanted fermentation. Toss the sauce.
-
Thick texture: Sauces naturally thicken over time. But major clumping, separating, or chunkiness indicates spoilage.

Expiration date: If your sauce is many months or years past its printed expiration date, it should be discarded even if it shows no other signs of spoilage.
When in doubt, remember that it’s better to be safe than sorry. If your sauce seems at all questionable, err on the side of caution. Black bean sauce is inexpensive and easy to replace.
