Da Hong Pao (Big Red Robe) is a Wuyi rock tea grown in the Wuyi Mountains. It is a heavily oxidized, dark oolong tea.
According to legend, the mother of a Ming dynasty emperor was cured of an illness by a certain tea, and that emperor sent magnificent red robes to clothe the four bushes from which that tea originated. Six of these original bushes, growing on a rock on the Wuyi Mountains and reportedly dating back to the Song dynasty, still survive today and are highly venerated.
Dahongpao is a very expensive type of tea since it must be harvested from these certain ancient tea trees on Wuyi mountain and is highly regarded among China for its healing properties.
