How long does hoisin sauce last in the fridge once opened?
Opened hoisin keeps 3–6 months in the fridge — take it from a clean edge of the jar, wipe the rim, and it’ll make the whole window.
How long does it keep?
| Pantry, from purchase | 18–24 months |
|---|---|
| Fridge, opened | 3–6 months |
Can it sit out?
Unopened, hoisin 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 hoisin sauce has gone bad
- White or blue fuzz where sauce has dried around the cap
- A sour, alcoholic edge over the sweetness
- A watery layer split off from the dark paste
- A dull brown where it should be glossy near-black
When in doubt, throw it out.
Hoisin is sweet before it’s savory — a spoonful of vinegar or soy pulls a flat-tasting glaze back into line.
