For tea that can be stored in the refrigerator, it is only suitable for cold storage, not for freezing, so it is best to store tea in the refrigerator. Because the freezing temperature is too low, the water in tea leaves will drain quickly. If the tea leaves are too dry, they are easily broken; If they go bad, the taste will change, and so will the taste of tea. After the refrigerated tea leaves are taken out of the refrigerator, they should be sealed and preserved in time after use, otherwise the tea leaves will easily condense water in the air, thus increasing the water content of the tea leaves and accelerating the deterioration of the tea leaves.

Tea leaves such as black tea, Pu 'er tea and scented tea don't need to be kept in the refrigerator. Because black tea belongs to fermented tea, the content of tea polyphenols in tea is small and easy to preserve. Scented tea has a strong floral fragrance, but low temperature storage will inhibit its fragrance and reduce its freshness and concentration. Pu 'er tea belongs to post-fermented tea and contains beneficial bacteria.

Matters needing attention in cold storage of tea

Tea is best stored in a refrigerator at about 10. If it is kept at about 0 to 5 degrees, the storage effect will be better. Tea has strong hygroscopicity and taste absorption. When tea leaves are stored in the refrigerator, we must pay attention to the compactness of tea leaves and the smell in the refrigerator. Be sure to seal the tea leaves first. In addition, tea leaves should be stored in the refrigerator. Don't put it with odorous objects to avoid odor.

At the same time, when the tea leaves are taken out of the freezer of the refrigerator, the temperature of the tea leaves in the teapot should be raised to room temperature before being opened and taken out, otherwise the low-temperature tea leaves will easily condense water in the air, thus increasing its water content and accelerating qualitative change.
