Wuyi teas are prized because of the distinctive terroir of the mountainsides where they are grown. Because of the lower yield produced by tea bushes in such terrain, the resulting tea can be quite costly. Tea made from the leaves of older bushes is particularly expensive and limited in quantity. Da Hong Pao, collected from what are said to be the original bushes of its variety, is among the most expensive teas in the world, and more valuable by weight than gold. Commercial-grade tea grown at lower elevations in the area accounts for the majority of the Wuyi tea available on the market. Commercial Da Hong Pao is made from cuttings of the original plants.
