Puer Tea Glossary - Zhi Zheng Tea Shop

„Yunnan Provincial Government has stipulated that for tea to qualify as Pu er it must be:

i) of the Broad Leaf variety (Sinensis Assamica)
ii) grown in the Lancang (Mekong) River region
iii) sun dried. The third point is important as there is much tea grown in the Lancang River area that is not sun dried.

There are also increasing amounts of Small Leaf Variety (Xiao Ye Zhong /小叶种) being grown in the Lancang River area.“
