What is the optimal temperature for storing tea leaves

The optimal storage temperature for tea is generally 0-5 degrees Celsius, and the specific temperature needs to be adjusted according to the type of tea. Green tea, fragrant oolong tea, and other fermented teas need to be stored at low temperatures, while black tea, pu erh tea, and other fermented teas can be stored at room temperature but should be kept away from light and moisture. Non fermented or lightly fermented teas such as green tea, yellow tea, and light aroma oolong tea are temperature sensitive, and high temperatures can accelerate chlorophyll degradation and oxidation reactions. It is recommended to seal this type of tea and place it in the refrigerator compartment, with a temperature controlled at 3-5 degrees Celsius. When refrigerating, aluminum foil bags or tin cans should be used to isolate moisture and odors, and avoid mixing with strongly scented food. After taking it out of the refrigerator, it should be allowed to stand at room temperature before opening to prevent condensation from corroding the tea leaves. Black tea, black tea, Pu erh tea and other fully fermented or post fermented teas can be stored for a long time in a cool environment at 20-25 degrees Celsius. Low temperature can actually inhibit its aging process, but it is important to note that the environmental humidity should not exceed 65%. Although white tea belongs to micro fermented tea, due to its special process, drying and storing at room temperature is more conducive to the action of active enzymes. Regardless of the type of tea, it should be kept away from areas with high temperature and humidity fluctuations such as kitchens and balconies, and avoid direct sunlight that can cause aromatic substances to evaporate. When storing tea leaves, in addition to controlling the temperature, attention should also be paid to sealing, avoiding light, and preventing odors. Use tin cans, purple clay cans, or aluminum foil composite bags to package tea leaves, and seal them promptly after each use. Different types of tea should be stored separately to avoid cross flavors. Regularly check the condition of the tea leaves, and discard them immediately if there is mold or obvious odor. By combining appropriate humidity and ventilation conditions, the color, aroma, and quality of tea can be maximally preserved.
