Puerh tea derives its name from the market town of Pu-er, where it was originally processed and sold. 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.

The secret of making Puerh tea has been closely guarded in China for centuries. The tea leaves are collected from growers of a special broad-leaf tea tree, which are said to be related to ancient prehistoric tea trees. The leaves go through two types of fermentation, which gives this tea its unique characteristics; a mild, but distinctively earthy flavour.
