| Fridge, opened | 3–6 months |
Can it sit out?
Unopened, black bean sauce is shelf-stable. Once opened, treat it as perishable — the FSIS 2-hour rule applies.
Perishable food left at room temperature for more than 2 hours should be thrown out — 1 hour if it’s 90°F or hotter (a picnic, a hot car, a summer kitchen).
How to tell if black bean sauce has gone bad
- White or green fuzz sitting on the surface of the paste
- A boozy, fermenting smell distinct from its usual salty funk
- A dried, cracked crust caked around the rim
- Rancid-smelling oil where it’s separated on top
When in doubt, throw it out.
Salted ferments smell strange by design — judge this jar by mold and by change from how it smelled new, not by funk alone.
