Wuyi Mountain has very unique climate, rocky soil and beautiful natural environment. There are 36 peaks, 72 caves, 99 prominent rocks and 108 scenic spots. The Stream with Nine Turnings is emerald green and crystal clear. The perfect combination of all these has made Wuyi Rock Tea a very special and precious species of Oolong Tea. Wuyi Rock Tea is categorized as: Zheng Yan Cha (Authentic Rock Tea), Ban Yan Cha (Half Rock Tea) and Zhou Cha (Continental Tea), based on the area where the tea is from. Out of the three, Zheng Yan Cha has the ¡°highest¡± aroma, most ¡°rocky¡± charm and the best quality. Zhou Cha has the least.
