Two factors of Pu-erh tea transformation

The basis of Pu-erh tea transformation is to rely on its own rich material content. The water content of Pu-erh raw tea is 10%-13% when it leaves the factory, which is the internal condition to ensure the normal conversion of the normal Pu-erh in the correct process.
 
　　When the relative humidity of the environment is between 50% and 75%, the water content of Pu-erh green tea under compacted state can be kept in a relatively stable state, keeping it from entering or exiting.
 
　　However, the humidity and dryness of the environment and the water content are determined by the conditions in different regions, just like the conversion rate between the north and the south is definitely different.

If the humidity in the north is too low for a long time, the Pu-erh tea will lose water, and the decrease in water content will not only slow down the aging rate, but also take away some substances during the process of water loss.
 
　　 If the humidity in the south is too high, the water in the environment will be absorbed by Pu-erh tea, and the increased water content provides suitable growth conditions for bacteria and molds, and it also brings odor to the process.
 
　　 Maintaining this moisture content, referred to as "moisturizing", is a crucial goal during the storage of Pu-erh tea. Therefore, no matter in the south or the north, we must go all out to achieve the goal of storing Pu-erh tea.
There are two main external factors that assist the aging of Pu-erh green tea: oxygen and temperature.
 
　　Pu-erh raw tea conversion is actually an oxidation process, where oxygen plays a role in accelerating the conversion. Therefore, the microcirculation of air can help to increase the conversion rate, but excessive ventilation will cause the Pu-erh tea to dehydrate too quickly, deteriorate or even weather. In the past, the storage environment we mentioned required "ventilation", which has been proven in practice. Such ventilation does not mean that it must be "open air", but it is regularly ventilated and moderately ventilated.
 
　　 And the temperature can also affect the conversion of Pu-erh tea. In the high temperature summer, the conversion speed is fast, and the low temperature winter conversion rate is relatively slow.
 
　　In summary: one internal factor moisture content, two external factors oxygen and temperature are the main factors affecting the conversion of Pu-erh green tea, and the external factors should be played through the internal factors.

　According to different storage places and different climatic conditions, it is necessary to comply with the conditions for the conversion of Pu-erh tea. Storage in different areas will form their own tea products. For example: Hong Kong warehouse, Guangdong warehouse, Dongguan warehouse, Kunming warehouse, etc. have formed their own unique tea drinkings.
