Pu'er is a large leafed tea from the Yunnan province in China and has been famous as a medicinal tea. The earliest records of Puerh tea date back to the Tang Dynasty ( 618AD-906AD ) when it was the favorite tea of the nobleman of this time. Puerh tea over the centuries has been used as a form of currency in China and an important international trading item. Puerh tea was at one time very well known in northern Canada among the northern native people, who were trading across the Bering Strait.
Pu'erh tea derives its name from the market town of Pu-er, where it was originally processed and sold, but it is grown on the Nuoshan Mountains. It is said that the unique taste of Puerh Tea was developed because it took weeks to transport the tea leaves by horseback to the town to be processed. During this transportation period the tea leaves would begin to ferment in the humidity and release a strong, fragrant aroma, which people found quite pleasant. A special technique of tea fermenting developed and Pu'er was thus created.
