How long does an opened jar of jam last in the fridge?
An opened jar of jam keeps 6–12 months in the fridge and a sealed one 6–18 months in the pantry — move it to the cold the day you break the seal.
How long does it keep?
| Pantry, from purchase | 6–18 months |
|---|---|
| Fridge, opened | 6–12 months |
Can it sit out?
Unopened, jam 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 jam has gone bad
- Fuzzy white, green, or gray spots on top — toss the jar rather than scooping around them
- A boozy, fermented smell
- Bubbles rising through the set, or a lid gone domed
- Toast crumbs and butter streaks worked down into it
When in doubt, throw it out.
A clean dry spoon every time is the whole trick — a butter-loaded knife is what ends a jar early.
