3 major standards of Lexinyuan ancient tree tea:

Standard 1: Selection of raw materials. Lexinyuan selects tea from ancient trees that are over 300 years old, and has strict requirements on the geographical location, soil minerals, water sources, and growing climate of the ancient tea trees.

Standard 2: Tea making process. LeXinYuan has established three specialized tea-producing teams stationed in the three core tea regions of XiShuangBanNa, Pu'Er (SiMao), and LinCang. These teams provide technical support and quality control services during the spring tea season to ensure optimal tea processing. 

Standard 3: Storage requirements. Lexinyuan Ancient Tree Tea strictly requires and ensures that all ancient tree teas are naturally aged in a suitable environment. All artificial aging and counterfeiting behaviors are rejected.We are indeed quite stubborn in the selection of Pu'er tea varieties and the determination of quality, and we do not want to cater to the market at will. As our lifelong career, we just want to have a clear conscience and provide customers with what we think is the best.
