Not necessarily. The quality of Pu'er tea mainly depends on the preservation method and whether the raw materials are high-quality. Whether it is raw Pu'er or cooked Pu'er, the material will change accordingly during the later storage process. Some teas will increase while others will decrease. Moreover, the quality of tea will not always improve. When all the contained substances are transformed, it will reach the highest peak of tea quality, and then it will slowly decline. Is the older the Pu'er tea, the better?
The aging of Pu'er tea is mainly affected by factors such as time, light, temperature, humidity and so on.
Generally speaking, raw Pu'er tea can be stored for 10-20 years, while cooked tea can be stored for 2-3 years.
It is recommended to use purple clay pots, covered bowls, elegant cups, and ceramic tea sets for brewing Pu'er tea.
