Can it sit out?
Unopened, chocolate syrup 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 chocolate syrup has gone bad
- Mold ringing the cap or the neck of the bottle
- A sour, fermented smell under the cocoa
- Syrup gone watery, grainy, or separated
When in doubt, throw it out.
Wipe the nozzle before you cap it — dried syrup on the spout is where the mold starts.
