Can it sit out?
Carton fruit juice is shelf-stable, so sitting out at room temperature isn’t the safety question — storage time is.
How to tell if carton fruit juice has gone bad
- A fizzy sting on the tongue in juice that should be flat
- A wine-like or vinegary smell at the spout
- Cloudiness, or a floating cap of mold inside the carton
When in doubt, throw it out.
Store the carton on a shelf, not in the door — juice reheats and re-chills every time the door swings.
