The suitable temperature for storing tea is between 0 and 25°C. According to national standards, the storage temperature for Green Tea and yellow tea should be between 0 and 10°C, while black tea, oolong tea, dark tea, and White Tea should be kept at temperatures no higher than 25°C. It is important to note that both excessively high or low temperatures can affect the quality of the tea. In addition to temperature, other factors to consider include avoiding light exposure, maintaining a normal room temperature, ensuring airtight seals, preventing dampness, and guarding against odors.
Suitable Temperature for Storing Tea
The temperature requirement for storing tea is 0 to 25°C, with a relative humidity below 50% to 70%.
Green tea: The storage temperature should ideally be controlled below 10°C, with a relative humidity below 50%.
Black tea: Should be controlled below 25°C, with a relative humidity below 50%.
Oolong tea: Should be controlled below 25°C, with a relative humidity below 50%.
Yellow tea: Should be controlled below 10°C, with a relative humidity below 50%.
White tea: Should be controlled below 25°C, with a relative humidity below 50%.
Dark tea: Should be controlled below 25°C, with a relative humidity below 70%.
Tea Storage Conditions
1. Temperature
If the temperature is too high, the quality of the tea will change easily, and the faster the temperature rises, the quicker the quality changes. At 0°C, the aging process of the tea can be inhibited, preserving its quality. Therefore, it is recommended to store tea in the refrigerator at home.
2. Humidity
Due to its porous nature, tea can absorb moisture very easily. If the moisture content of the tea exceeds 5%, it will easily deteriorate. When storing tea, it is important to maintain dry conditions. Paper tubes are not recommended for storing tea due to their poor moisture resistance.
3. Vacuum
Tea contains vitamins, theaflavins, thearubigins, and polyphenols, which are prone to oxidation when exposed to oxygen. Oxidized substances can cause the tea to develop stale flavors, compromising its quality. When storing tea, you can use vacuum packaging to remove oxygen. For canisters, choose Containers of appropriate size, fill them as much as possible with tea, minimize the air inside, and then seal them for storage.
4. Light Avoidance
Direct exposure to light can cause changes in the internal components of tea, with stronger light causing more obvious changes. Transparent containers should not be placed in direct sunlight. Canned, tubed, and boxed teas should not be stored in areas where they are exposed to light for extended periods.
5. Surrounding Environment
The containers used for storing tea must be clean and odor-free, as tea is susceptible to absorbing surrounding odors. Newspapers should not be used to directly wrap tea, nor should plastic Bags or boxes that have previously been used to package biscuits, milk powder, dried fruits, etc., be used to store tea. Even well-packaged tea should not be stored in kitchens, wardrobes, or cabinets, and particular care should be taken not to store it alongside items like soap.
