Origin:
"Hóng Yù" a cultivar developed by the Taiwan Tea Research and Extension Station (TRES) during the Japanese occupation in the early 20th century. Known as TTES18, it is a hybrid of the Assamica variety from Myanmar and the local Taiwanese wild variety, Shan Cha.
Historical Context:
Initially developed to compete with Indian teas, this variety has retained its unique and memorable bouquet with menthol, camphor, and cinnamon notes.
Cultivation Region:
Primarily grown in the Yuchi district (Nantou County) in the hills surrounding Lake Ri Yue Tang at altitudes of 700–1000 meters. Today, it spans approximately 10,000 hectares.
Unique Production Method:
The tea's natural sweetness is a result of the fostered relationship with insects.
The native Leafhopper (Jacobiasca formosana) spends its time throughout the growing season laying eggs and biting the tea plant, which causes the plant to produce two compounds, monoterpene diol and hotrienol.
This defense mechanism, in addition to Leafhopper eggs, results in this Taiwanese Black tea's unique flavor.
