The characteristics of Lishan Oolong tea: Good sweetness: Lishan Oolong tea grows in the tea area from 1600 meters to 2500 meters. The cold mountain environment and the large temperature difference result in less bitterness and good tea soup sweetness. … Unique floral fragrance: Because it is not easy to plant tea in a mountain environment, local farmers use a lot of organic fertilizers and develop irrigation systems. Therefore, Lishan Oolong tea leaves are thick and rich in gums, and the produced tea leaves have a special floral fragrance.
