Cloud tea (Chinese: 雲雾茶; pinyin: yún wù chá; pronounced [y̌n û ʈʂʰǎ]) is a Chinese green tea that originally comes from Nanyue Mountain. It is named for the clouds of Le Mountain (南岳山; nányuè shān) where it is produced. In ancient times, it was called Le tea. During the Tang dynasty, it was used as tribute to the emperor. Cloud tea grows in the area of Guangji Temple, Tiefu Temple and Huagai Peak at an altitude of 800 to 1,100 metres (2,600 to 3,600 ft) with a mild and wet climate. Meanwhile, rich organic matter in the soil is extremely suitable for the tea's growth. The Chinese great tea master, Lu Yu in the Tang dynasty, once mentioned it in The Classic of Tea, which provides for the reputation of cloud tea in Le Mountain. In general, it is famous not only for its thin leaf and beauty, but also the fresh colour, cool taste and attractive smell. It has won an outstanding reputation in both Hunan Province and abroad.
