Should You Keep Grapes In The Refrigerator

Yes, refrigerate grapes to keep them fresh for two to three weeks

Grapes last much longer in the refrigerator than on the counter. At room temperature, they soften and begin to ferment within a few days. In the refrigerator, they stay firm and flavorful for two to three weeks because the cold slows down the ripening process and the growth of mold, which is the main reason grapes spoil.

The key is how you store them. Grapes cling to moisture, and excess water on the surface speeds decay. Store them unwashed in a breathable container—a paper bag, a produce drawer, or even a perforated plastic bag—so air can circulate around them. The goal is to keep them cold and dry at the same time.

Key Takeaways

• Refrigerate grapes in their original packaging or a paper bag to extend their life to two or three weeks instead of a few days.
• Do not wash grapes before storing them; moisture on the skin promotes mold growth and speeds spoilage.
• Store grapes in the coldest part of your refrigerator, usually the back of the bottom shelf or a dedicated produce drawer.
• Wash grapes just before eating them, and remove any that show soft spots or mold to prevent the rest from spoiling.

Why the refrigerator works better than the counter

Grapes are a living fruit. Even after harvest, their cells continue to respire—they take in oxygen and release carbon dioxide and ethylene gas. Ethylene is a plant hormone that triggers ripening. At room temperature, this process happens fast, and the grapes soften within days. Cold slows respiration dramatically, which means the grapes stay firm longer and ethylene production drops.

Mold is the other reason grapes fail quickly at room temperature. Grapes have a natural waxy coating that resists mold, but warmth and humidity create the perfect environment for fungal spores to germinate. A refrigerator is cold and, if your produce drawer is working properly, maintains steady humidity without being wet. That combination keeps mold at bay.

How to store grapes so they last the full three weeks

Leave grapes in their original plastic clamshell or bag if they came that way. If you bought loose grapes, transfer them to a paper bag or a produce bag with small holes punched in it. The container should allow air to move around the grapes without letting them dry out completely. Avoid sealed plastic bags, which trap moisture and create a humid microclimate where mold thrives.

Place the bag or container in the coldest part of your refrigerator. For most models, that is the back of the bottom shelf or a dedicated produce drawer set to high humidity. Do not store grapes near the door, where temperature fluctuates each time you open it. Grapes are sensitive to temperature swings, and the door is the warmest spot in the fridge.

Check the grapes every few days. If you see any with soft spots, mold, or a wrinkled appearance, remove them right away. A single moldy grape can spread spores to its neighbors, so catching decay early protects the rest of the bunch.

Why you should wash grapes just before eating, not before storing

Water on the grape skin is an invitation to mold. When you wash grapes and store them wet, you are creating the exact conditions mold needs to grow—moisture, cool temperature, and time. Even a light dampness left from rinsing can be enough to trigger decay within a few days.

Instead, store grapes dry and wash them in a colander under cool running water just before you eat them. Rub them gently with your hands or a soft cloth to remove any dirt or debris. If you want to prep grapes ahead for snacking, wash and dry them thoroughly, then store them in a paper towel-lined container so any remaining moisture is absorbed. This works for a day or two, but not for the full three-week window.

Storing different types of grapes

Green grapes and red grapes follow the same rules—both last two to three weeks in the refrigerator when stored unwashed in a breathable container. Red grapes sometimes soften slightly faster than green ones, but the difference is small enough that storage method matters more than color.

Seedless grapes are more delicate than seeded varieties because the breeding process that removed the seeds also made the skin thinner. They spoil a bit faster, so check them more often and remove any soft ones promptly. Still, refrigeration extends their life significantly compared to the counter.

Muscadine grapes and other thick-skinned varieties are more forgiving. Their tougher skin resists mold better, and they can last three to four weeks in the refrigerator. Store them the same way—unwashed, in a breathable container, in the coldest part of the fridge.

What to do if grapes start to soften or show mold

Soft grapes are still safe to eat if there is no mold or off smell. Softness means the cell walls have broken down and the fruit is losing firmness, but the grape itself is not spoiled. You can eat soft grapes right away, freeze them for later use in smoothies, or remove them from the bunch so they do not spread decay to the rest.

If you see white, gray, or fuzzy growth on a grape, that is mold. Do not eat it. Remove the affected grape and any others touching it, then inspect the rest of the bunch. Mold spores are invisible and can spread before you see visible growth, so if more than a few grapes are affected, it is safer to discard the whole bunch.

A sour or fermented smell means the grapes have begun to break down internally. This happens when they are stored too warm or too long. Discard them—the flavor will be off, and fermentation can produce compounds that upset your stomach.

Freezing grapes for longer storage

If you have grapes you will not eat within three weeks, freeze them. Wash and dry them completely, spread them on a baking sheet in a single layer, and freeze for two to three hours until solid. Then transfer them to a freezer bag or airtight container. Frozen grapes last three to four months.

Frozen grapes work well in smoothies, as a cold snack on a hot day, or thawed slightly and added to salads. They will not have the same firm texture as fresh grapes because freezing breaks down cell walls, but the flavor is preserved. Do not expect to eat them straight from the freezer like fresh grapes—they will be mushy once thawed.

Frequently Asked Questions

Can I wash grapes and store them for the week?

Yes, but they will not last as long as unwashed grapes. Wash them, dry them thoroughly with a clean cloth or paper towels, and store them in a container lined with paper towels to absorb any remaining moisture. They will keep for three to five days this way. For the full two to three weeks, store them unwashed.

Do grapes need to be in the crisper drawer?

A crisper drawer set to high humidity is ideal, but grapes will also last well on a regular shelf in the coldest part of the fridge. The most important thing is keeping them cold and away from the door. If your crisper is full, do not worry—a paper bag on the bottom shelf works fine.

Why do my grapes get moldy so fast?

The most common cause is storing them washed or in a sealed plastic bag where moisture builds up. The second cause is keeping them too warm—near the door or on a shelf that is not as cold as the back of the fridge. Check that your refrigerator is set to 35 to 38 degrees Fahrenheit, and always store grapes unwashed in a breathable container.

Are grapes safe to eat if they are wrinkled?

Wrinkled grapes have lost water and firmness, but they are still safe if there is no mold or off smell. They will taste less sweet and have a softer texture. Eat them right away or freeze them for smoothies. If wrinkles appear after just a few days, your refrigerator may not be cold enough.

Can I store grapes in a glass container?

Glass containers work, but they trap moisture unless you line them with paper towels to absorb condensation. A paper bag or perforated plastic bag is simpler because air moves through naturally. If you prefer glass, change the paper towel lining every few days to keep the grapes dry.
