This Taiwanese oolong is grown on the rocky cliffs of the A-Li Shan mountain range in the Nantou County of Taiwan. The tea is
harvested at 6,600–7,800 feet above sea level. Due to the paucity of
agricultural land at such high altitudes, the quantity of A-Li Shan oolong
harvested every year is relatively limited, ensuring that it is always
in great demand.
