aka Big Red Robe Oolong
This rare tea 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 great red robes to clothe the four bushes from which that batch of tea originated. Six of the 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.
