What is the appropriate temperature for tea cold storage?

　　Tea is a commodity that is very sensitive to temperature and humidity, and its quality and shelf life are directly affected by environmental conditions. In order to ensure the quality and shelf life of tea, it is crucial to correctly set the temperature of the tea cold storage. The following is a scientific guide to setting the temperature of the tea cold storage.

　　Temperature requirements for tea

　　The storage temperature of tea is one of the important factors affecting its quality. Generally speaking, the ideal storage temperature of tea depends on its type and processing method, but it is usually between 0℃ and 25℃. However, the temperature setting of the tea cold storage should take into account the following aspects:

　　Different types: Different types of tea such as green tea, black tea, and oolong tea have different temperature requirements. For example, green tea is more suitable for storage at a lower temperature, while black tea and oolong tea can be stored at a slightly higher temperature.

　　Humidity association: The storage temperature of tea is usually closely related to humidity. At higher temperatures, lower humidity is required to avoid dampness and mold of tea; while at lower temperatures, higher humidity can be allowed to maintain the moisture of tea.

　　Quality maintenance: Too high a temperature will cause the volatile components in the tea to evaporate, affecting its aroma and taste; while too low a temperature may cause the tea to deteriorate and lose its fragrance.

　　Recommended tea cold storage temperature setting

　　Based on the above considerations, it is recommended that the temperature of the tea cold storage be set within the following range:

　　Green tea: 0℃ to 5℃. Lower temperatures help maintain the color and aroma of green tea and extend its shelf life.

　　Black tea, oolong tea: 5℃ to 15℃. These teas can also maintain good quality at lower temperatures, but are not as sensitive to temperature as green tea.

　　Pu’er tea: 10℃ to 20℃. Pu’er tea usually requires higher humidity to maintain its unique aging process, so it can be stored at higher temperatures.

　　Precautions

　　Temperature stability: Regardless of the temperature setting selected, the temperature of the tea cold storage should remain stable to avoid drastic fluctuations that affect the quality of the tea.

　　Humidity control: In addition to temperature, the tea cold storage also needs to pay attention to humidity control to ensure that the tea is not damp and moldy.

　　Air circulation: Regular ventilation ensures air circulation inside the tea cold storage to avoid odor and mold.

　　In summary, the temperature setting of the tea cold storage needs to take into account factors such as the type of tea, humidity requirements, and quality maintenance, and ensure stability and appropriate air circulation to ensure the quality and shelf life of the tea.
