Authentic Wuyi Yan Cha is produced in the Mount Wuyi region a UNESCO natural heritage site. The Wuyi mountain region has 39 peaks, 99 valleys and a river with 9 bends. The area has largely intact subtropical forest and tall cliffs, where the tea plants grow in narrow valleys between them. Tea has been processed here from around 11th century, at start mostly green tea for imperial court. Wulong teas started around 17th century mostly for export to Europe. At that time, Wuyi was known in England as "Bohea". The mountain peaks aren't incredibly high, but they are constatnly shrouded with fog and mist. The sun creates rainbows around tea bushes later at evening, the moister settles on the rocks and trickles down to supply tea plants with enriching minerals. The prime area of Wuyi Shan, where this Cliff Tea is grown, is a National Reserve area with a strict prohibition of pesticides & fertiliser usage.
