Expiration & Storage Tips
When does green grapes expire?
Unopened green grapes, stored in the refrigerator, can last up to two weeks. Once opened, they generally retain their best quality for about three to five days. If you freeze them, they can keep indefinitely, though the texture and taste might change after six to twelve months. Compared to the printed date on the package, you might have a little extra time, but it's generally a good idea to follow it for the freshest taste.
How do you tell if green grapes is bad?
You can tell if green grapes have gone bad through a combination of signs. If they're shriveled, darkened or have a slimy texture, those are clear signs they're past their best. A strong, fermented smell is another indication, as well as the presence of mold. Keep in mind that just a few bad grapes don't mean the whole bunch is bad – remove the spoiled ones and eat the rest promptly.
Tips for storing green grapes to extend shelf life
• Always store your green grapes in the refrigerator in a breathable plastic bag. This allows a little air flow, which helps prevent too much moisture from collecting and promoting the growth of mold.
• Wash the grapes just before you're about to eat them. Cleaning them then storing can make them spoil faster due to the extra moisture.
• If you notice a few bad grapes in the bunch, remove them. One spoiled grape can speed the spoilage of others nearby.
• Green grapes can be frozen for long term storage. Freezing may change the texture slightly but frozen grapes make a refreshing summer snack or an excellent addition to smoothies.
• If you want to extend the shelf life of a big grape harvest, consider making grape jam or juice.
