Winter is the peak season for grapes. However, due to low temperatures and high humidity, grapes are prone to rot and spoilage. To ensure the quality of indoor grapes in winter and extend their shelf life, this article will introduce some simple and practical methods and tips.

Reasonable Harvest Time
The maturity of the grapes is key to preservation. Choosing the right time to harvest, that is, picking the grapes when they are at their peak ripeness, can extend their shelf life.
Careful Packaging
Divide the grapes into small bunches, wrap them in clean paper, and secure them with tape. This can prevent the grapes from crushing each other and avoid contamination from the outside.

Control Storage Temperature
Suitable room temperature is key to storing grapes indoors in winter. Generally, storing grapes in an environment of 15-18°C can extend their shelf life.
Humidity Control
The humidity in winter is high, which can easily lead to dampness and spoilage of grapes. In the room where grapes are stored, you can install a dehumidifier or use desiccants to ensure moderate humidity.
Avoid Direct Sunlight
Sun exposure can cause the grape skins to dry and crack, affecting the quality of the fruit. Placing the grapes in a shaded area away from direct sunlight helps to extend their shelf life.

Regular Inspection
During storage, check the condition of the grapes regularly. If any signs of rot are found, remove the affected grapes promptly to prevent spoilage of the others.
Avoid Storing with Other Foods
Grapes are a strong-smelling fruit and can easily absorb odors from other foods. Avoid storing them with other items to prevent their taste and flavor from being affected.
Tap Test
Tap the grape gently. If it makes a crisp sound, it is fresh; if it sounds dull, it has started to spoil.
Appropriate Moistening
The indoor air can be dry in winter. You can slightly moisten the storage environment to maintain the grapes' moisture and freshness.
Maintain Ventilation
Proper ventilation helps to remove odors and carbon dioxide from the storage room, keeping the grapes fresh.
Avoid Crushing
Grapes are delicate and fragile fruits. Avoid heavy pressure and crushing to prevent damage and spoilage.
Unpack and Spread Out
When grapes are stored densely, unpack and spread them out regularly to ensure ventilation and space between bunches, preventing spoilage from spreading.
Pest Control Measures
When storing grapes in winter, pay attention to pest control. You can use natural repellents like orange peels, lemon peels, or mint leaves in the storage area to protect the grapes from pests.
Regular Wiping
Regularly wipe the containers used for storing grapes to keep them clean and hygienic, preventing contamination.
Reasonable Use of a Refrigerator
If you have a refrigerator, you can store the grapes inside to maintain their freshness and taste.
By using the methods and techniques above, we can easily extend the shelf life of indoor grapes in winter and enjoy their fresh and juicy taste. Remember, scientific storage is the key to preserving grapes. Hope these tips are helpful to you.
