The leaves of Tung Ting Oolong are grown in the Tung Ting region in Taiwan at the specific elevation of 2500 feet/740 meters. At this elevation, the leaves absorb moisture from the surrounding fog and clouds every morning and every afternoon which is ideal for Oolong plants. Due to the unique geographic location and stringent selection of leaves, this is the finest Tung Ting Oolong from the Tung Ting estate.
