Wuyi rock-essence tea, a famous kind of oolong in China, grows in the Wuyi Mountain of Fujian Province. The tea gets its name for that the tea plants grow on the rocks of the Wuyi Mountain. Since the Tang Dynasty, tea leaves of Wuyi Mountain became a precious kind of tea offered to the upper class; and an imperial tea garden was set in the Wuyi Mountain to specially gather and produce tea for the imperial family. Since the Ming Dynasty, people began to develop oolong, to which Wuyi rock-essence tea belongs.
Tea leaves from the heartland of Wuyi Mountain, called “Zhengyan Tea”, are the most excellent among all kinds of Wuyi rock-essence tea. As these tea leaves are brewed in the water, they smell sweet and mellow for a long time and taste without bitter or acerbity. This unique sweet smell is called “Yanyun (Lasting Appeal of Rock)”.
