What kind of tea needs to be refrigerated for storage

Green tea, light aroma oolong tea, yellow tea, etc. need to be refrigerated for storage, while black tea, black tea, Pu erh ripe tea, etc. can be stored at room temperature. The preservation method of tea is mainly related to the degree of fermentation. Unfermented or lightly fermented tea is prone to oxidation and requires low-temperature preservation, while fully fermented tea is suitable for aging at room temperature. Green tea is prone to chlorophyll degradation due to oxidation at room temperature, and refrigeration can delay this process. Controlling the temperature between 0-5 degrees Celsius can effectively inhibit enzyme activity and prevent tea color from turning yellow and aroma loss. Use aluminum foil bags or tin cans with good sealing to prevent refrigerator odors from entering. After being removed from the refrigerated environment, it should be allowed to stand at room temperature before opening to avoid moisture caused by condensation.

Fragrant oolong tea such as Tie Guan Yin is sensitive to temperature, and high temperatures can accelerate the volatilization of aromatic substances. Refrigeration can preserve its unique orchid aroma and refreshing taste, but it is important to be cautious of foods with strong odors. If partially roasted oolong tea is planned to be consumed in the short term, it can also be stored in a cool and dark place, but it is still recommended to refrigerate it after more than a month. As a lightly fermented tea, the unique flavor formed by the yellowing process of yellow tea is easily influenced by the environment. Low temperature storage can prevent excessive oxidation of polyphenolic substances and maintain a mellow taste. Special attention should be paid to sealing and moisture prevention, as the moisture content of yellow tea is slightly higher than that of green tea during the production process, making it more susceptible to moisture absorption and deterioration. If the color of the tea soup becomes darker and the aroma weakens, it may indicate a change in quality. Whether stored in refrigeration or at room temperature, tea should be kept away from direct sunlight and humid environments. Unopened tea leaves can be refrigerated as a whole, while opened tea leaves are recommended to be divided into small portions to reduce the number of times they are opened. Seal the tea immediately after each serving to avoid frequent temperature changes affecting its quality. It is best to consume refrigerated tea within six months to enjoy the best flavor. Paired with traditional containers such as purple clay pots and ceramic pots for storage, it can regulate humidity and avoid cross flavors, making it an ideal choice for long-term tea storage.
