After how long are grapes edible?

The edibility duration of grapes depends on several factors such as the grape variety, storage conditions, and individual preferences.

On average, fresh grapes can be edible for:

1. At Room Temperature: When stored at room temperature (around 20-25°C or 68-77°F), grapes usually stay edible for 3-5 days. Room temperature storage causes grapes to soften and lose moisture more quickly.

2. In the Refrigerator: Grapes stored in the refrigerator can last longer. Properly refrigerated grapes, ideally in a sealed container or plastic bag, can remain edible for about 1-2 weeks. Cold storage helps maintain firmness and reduces moisture loss.

3. Frozen Grapes: Freezing grapes is an excellent way to extend their shelf life significantly. Grapes can be frozen for up to 6-12 months. Before freezing, it's recommended to wash and remove stems, then spread the grapes in a single layer on a baking sheet and freeze for a few hours before transferring them to a freezer-safe container.

Remember that different grape varieties may have slightly different edibility durations. Additionally, it's essential to inspect the grapes before consumption; any moldy or rotten grapes should be discarded. If grapes develop any off-odors, flavors, or changes in texture, it's best to discard them as well.
