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.
