Taiwanese tea includes four main types: oolong tea, black tea, green tea and white tea. The earliest record of tea trees found in Taiwan is from 1717 in Shui Sha Lian (水沙連), present-day Yuchi and Puli, Nantou County.[1] Some of the teas retain the island country's former name, Formosa.
Oolongs grown in Taiwan account for about 20% of world production.[2]
