It is now the hottest time of the year, and most regions in the south have entered a hot and humid state. At this time, tea enthusiasts who have tea in their possession will face a severe challenge of storing tea during the summer. As we all know, tea leaves are very susceptible to environmental influences, and the requirements for storing tea are extremely strict. Especially with Pu'er tea, if stored well, it can become more fragrant over time and have collection value; if not stored properly, the tea can spoil, losing its drinking value and causing significant economic losses for individuals or businesses. Understanding the principles of tea transformation before storing tea is crucial for scientific storage. Factors Affecting Tea Transformation or Spoilage In fact, the transformation of tea leaves is directly related to temperature, humidity, oxygen, and light. Generally, the higher the temperature, the greater the humidity, the more sufficient the oxygen, and the stronger the light, the faster the oxidation, hydrolysis, polymerization, and other chemical reactions of the substances within the tea leaves will occur, resulting in a quicker change in taste components. Temperatures that are too high or too low are not conducive to the transformation…

Liubao tea, Anhua dark tea, raw Pu'er tea, ripe Pu'er tea, and Fuding white tea can be stored for a long time. These teas are post-fermented or aged over time.
