How long does balsamic vinegar last after opening?
USDA gives opened balsamic 18 months in the fridge and a sealed bottle 3–5 years in the pantry — cap it tight either way, since air is what flattens it.
How long does it keep?
| Pantry, from purchase | 3–5 years |
|---|---|
| Fridge, opened | 18 months |
Can it sit out?
Unopened, balsamic vinegar 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 balsamic vinegar has gone bad
- A harsh, solvent-like sharpness where the sweetness was
- Sediment thickened into sludge at the bottom
- Fuzzy growth around the neck or under the cap
- A thin, watery pour from a bottle that used to run syrupy
When in doubt, throw it out.
Cheap balsamic reduces beautifully in a pan; the aged syrupy kind is for drizzling raw — heat burns off exactly what you paid for.
