Pu’er, often referred to as a ‘dark tea’, hails from the fertile Yunnan Province in southwestern China, the birthplace of tea itself. Here, in the legendary forests of Xishuangbanna, one can find the oldest tea trees in the world, some of them 30 metres tall and over 1,000 years old. Made from the large tea bush leaves indigenous to this mountainous region, Pu’er can be sold as loose-leaf or compressed into the traditional disc-like cakes, as well as other interesting shapes such as cubes, mushrooms and pyramids.
