The stored Pu-erh tea can achieve the benefit of getting older and more
fragrant, so what are the conditions for "storing well"? Or to say:
what determines the conversion result of Pu-erh tea?
1. Material basis.
The material basis for the conversion of Pu-erh tea is to rely on the rich material content of Yunnan big leaf. The water content of Pu-erh raw tea is about 10% when it leaves the factory, which is the inherent condition for the normal conversion of raw Pu-erh to ensure the correct process.
2. Internal factors.
When the relative humidity of the environment is between 50-70%, the water content of Pu-erh green tea under the state of raw material compaction can be relatively stable and can not be kept in or out. In the north, where the humidity is too low, the dry environment for a long time will make Pu-erh tea 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. In the south, where the humidity is too high, the moisture in the environment will be absorbed by the Pu-erh tea, and the increased water content provides suitable growth conditions for bacteria and molds, and at the same time brings a smell to the process.
Therefore, maintaining this moisture content, referred to as "moisturizing" for short, is a crucial goal in the storage of Pu-erh tea. Whether in the South or the North, the means of storage must go all out to achieve this goal.
3. External causes.
There are two main external factors that assist the aging of Pu-erh raw tea, oxygen and temperature.
The conversion of Pu-erh raw tea is an oxidation process, and oxygen is here to accelerate the conversion. Therefore, the microcirculation of air can help increase the conversion rate, but excessive ventilation will dehydrate and degrade Pu-erh tea. In the past, the storage environment "ventilation" has been rejected by a large number of facts in the course of practice. This is particularly worthy of attention.
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 speed is slow.
In summary, the water content of one internal factor, oxygen and temperature of two external factors are the main factors affecting the conversion of Pu-erh green tea. According to the different climatic conditions in various regions and the conditions for the conversion of Pu-erh tea, different warehouses will form tea products with local climate characteristics. Observing and experiencing this process is one of the pleasures in the collection of Pu-erh tea.
