Yes. Juice cartons and fruit punch last 8–12 days in the fridge. After that, or sooner if stored badly, they spoil: watch for the signs below.
How to tell if juice cartons and fruit punch are bad
Smell
Vinegary, sour or musty instead of fresh.
Taste
Flat, sour or bitter — quality is gone.
Look
Cloudiness, sediment or film that was not there before.
Package
Bulging carton, cap or can — discard.
Juice cartons and fruit punch past the expiration date
Unopened
FoodKeeper gives unopened juice cartons and fruit punch 3 weeks in the pantry, counted from the day you buy it. "Best-by" and "sell-by" describe quality and stock rotation, not safety; only infant formula carries a federally required use-by date.
Opened
Once opened, the printed date no longer applies. Count 8–12 days in the fridge or 7–12 days in the pantry from the day you open it.
How to keep juice cartons and fruit punch fresh longer
- Store unopened in a cool, dark place.
- Refrigerate after opening and close tightly.
- Keep away from light and heat, which flatten flavour.
