Expiration & Storage Tips
When does grapes expire?
Unopened grapes, if left on the counter, can spoil in just a few days, while if refrigerated, they can last up to 7-14 days. Also, note that their freshness is influenced by the sell-by date on the package. Once opened or separated from their bunch, they may only last 3-5 days in the refrigerator. Frozen grapes can be delightfully refreshing, especially in hot weather, and can last up to 10-12 months when kept in the freezer.
How do you tell if grapes is bad?
If grapes have gone bad, they lose their firm quality and become soft and squishy. Their color may change, and spots may develop on their surface. In the worst-case scenarios, mold may start to grow, particularly if the grapes have been stored in a humid environment. If grapes are off, they will also emit a fermented or vinegar-like smell. When any of these signs occur, it's certainly time to toss them out.
Tips for storing grapes to extend shelf life
• Keep your grapes in the fridge nestled in a ventilated, preferably perforated, plastic bag to maintain freshness. Don't remove them from the original packaging immediately as it’s often designed to allow the right amount of air flow.
• Always wash your grapes just before eating them to avoid speeding up the decay process. Grapes naturally have a protective coating that wards off bacteria and yeast.
• If you're planning to freeze your grapes, wash them thoroughly and dry them before placing them in the freezer. It’s best to separate them from their bunch and spread them out on a tray before freezing, to prevent them sticking together. Once frozen, transfer them to a resalable bag for longer storage. To thaw, just leave them at room temperature for a couple of hours.
• Be sure to consume any bruised or damaged grapes first as they can make other grapes in the bunch go bad more quickly. Minimize touching the remaining grapes to reduce any potential transfer of bacteria.
