Puerh History - Pu-erh.Net

„The most classical Puerh Tea is the Bingcha, recorded in Yong-Zheng 13th year in Qing Dynasty (1735). Each tea cake weighs 7 Liang (357 grams). Seven cakes make 1 Tong (wrapped in leaves), weighing 49 Liang. It was sold in nice places and also was exported abroad. It was re-named as "Yunnan Qizi bingcha - Yunnan seven cake tea" during the Cutural revolution.“

„There is also knowledge that you can gain from drinking the same tea over and over again that you cannot from sampling. This may involve the tea changing on you – a traditionally stored puerh gradually losing its storage taste, for example. Or, it can just be that you start noticing nuances that were there, but were not necessarily obvious the first few times you try it.“
