Do Grapes Spoil If Not Chilled?

Grapes, the delicious fruit we love to consume, are known to be an excellent source of natural sugar. Whether you snack on them alone, dress up a salad or charcuterie board, or use them in any number of recipes, these plump little bundles of sweetness seem to make everything better. However, once we bring them home, there is usually a question of how to store them.

Do Grapes Go Bad?

The short answer is, yes, they do. However, the time it takes for them to spoil depends on a variety of factors – how they were stored, the type of grape, and the temperature they were exposed to, among other things. To obtain the maximum shelf life, proper storage is crucial.

Factors Affecting Grape Shelf Life

To determine the shelf life of grapes, several factors including storage conditions, grape type, and picking time play a crucial role. Let’s explore each of these factors in depth in the following paragraphs.

Storage Temperature

The optimal temperature for storing grapes is between 32-35℉. At this temperature, grapes should last for up to five days. If stored at room temperature, grapes will last for only two days before they start to degrade, become softer, and eventually lose their fresh texture.

Grape Type

There are several varieties of grapes, including green, black, and red. Green grapes usually have a slightly longer shelf life than their red and black counterparts. Red and black grapes tend to have a shorter shelf life because they are more delicate and ripen quickly. As a result, they tend to turn soft and mushy more quickly than green grapes.

Picking Time

The timing of harvesting the grapes can also affect their shelf life. If grapes are picked too early or too late, they will start to degrade more quickly than if they were picked at the optimal time. When the grapes are harvested, they should be firm, with a glossy look, and plump skins.

How to Store Grapes to Extend Their Shelf Life?

Proper storage is crucial in extending the shelf life of grapes. Here are some of the best storage practices:

Keep Them Dry

Before storing, ensure that your grapes are dry. Any moisture will quickly lead to mold growth and spoil the grapes. You can simply blot them with a paper towel if needed.

Refrigerate Grapes

Refrigeration is the most effective way to extend the shelf life of grapes. Place them in a sealed container or a plastic bag with some ventilation to prevent them from getting moldy. Once opened, consume them within a few days.

Avoid Moisture

Ensure that the grapes are not exposed to moisture or wet conditions, as any moisture will encourage mold growth, deteriorating the fruit’s quality.

Sort the Grapes

Remove any damaged or spoiled grapes before refrigeration. This slows down the degrading process, allowing the healthy grapes to last longer.

Grape Storage Tips and Tricks

Here are some additional storage tips and tricks that will help extend the shelf life of your grapes:

Storage Bags

Consider purchasing a grape storage bag. They are sold in stores and online and are designed for optimal grape storage. These bags keep the grapes cool and dry, provide ventilation, and have a special lining that prevents the grapes from absorbing moisture.

Baking Soda

Placing an open box of baking soda in the refrigerator will help absorb any moisture, and therefore prevent mold growth. This age-old trick works for extending the shelf life of all fruits and vegetables, not just grapes.

Lemon Juice

Sprinkling a few drops of lemon juice over your grapes before storage can help prevent mold growth, keeping your grapes fresher for longer.


In conclusion, grapes have a limited shelf life, typically lasting only a few days if not stored appropriately. Proper storage plays a crucial role in extending their shelf life. Refrigerated storage between 32-35℉ combined with the proper sorting, drying, and bagging techniques, can help you extend the shelf life of your grapes for up to five days or more.


  • Do grapes last longer in the fridge or on the countertop?
  • Storing grapes in the refrigerator is the most effective way to extend their shelf life. Grapes stored in the fridge can last up to five days or more, while grapes stored on a countertop typically last no longer than two days.

  • Are grapes okay to eat if they are wrinkled?
  • Wrinkled grapes are a sign of dehydration and will likely have lost their taste and texture. Instead of consuming wrinkled grapes, it’s better to toss them out.

  • Can you store grapes in an airtight container?
  • Yes, you can store grapes in an airtight container, but ensure that the container has proper ventilation in place to allow the grapes to breathe.

  • Can grapes be frozen?
  • Yes, grapes can be Frozen. Remove the grapes from the stem, rinse them under cold water, and set them on a dry towel to allow them to dry. Place the grapes in an airtight container or bag, and freeze.
