Should grapes be refrigerated or kept at room temperature

Grapes are recommended to be refrigerated during high temperatures in summer, and can be stored at room temperature during spring and autumn when the room temperature is suitable. The preservation method of grapes is mainly influenced by factors such as temperature, humidity, maturity, storage time, and stem status. Cold storage of grapes can effectively delay spoilage and deterioration. The temperature in the refrigerator compartment is usually controlled at around 4 degrees Celsius, which can inhibit microbial growth and slow down the softening rate of fruit pulp, especially suitable for fully ripe grapes. Before refrigeration, it is necessary to cut off the rotten fruit pieces, wrap them in kitchen paper, and put them in a breathable fresh-keeping bag to avoid condensation and mold growth. However, refrigeration for more than 5 days may cause the fruit stems to dry up and affect the taste.

Room temperature storage is more suitable for immature green grapes. A ventilated environment of around 20 degrees can promote post ripening and enhance sweetness, but it is necessary to avoid direct sunlight. Hanging the entire string for storage can reduce compression damage, and placing the stem facing upwards can delay water loss. If stored at room temperature for more than 3 days, it is necessary to check for any fermented wine odor. If it deteriorates, it should be discarded immediately. Regardless of refrigeration or room temperature storage, grapes should be kept dry and ventilated, and rinsed with running water before consumption. Avoid freezing storage, as thawing may cause the meat to become soft and rotten, resulting in water leakage. When purchasing, choose fresh grapes with evenly distributed fruit powder and emerald green stems. Multiple purchases in small quantities can maximize the preservation of flavor. For those with gastrointestinal sensitivity, it is recommended to eat without skin to reduce the irritation of dietary fiber to the gastrointestinal mucosa.
