The Unique Terroir of Sun Moon Lake Black Tea
Located at an elevation of approximately **800 meters**, Yuchi Township benefits from diverse terrain, rich natural conditions, an ideal annual average temperature, and stable humidity. These unique environmental factors have created the perfect foundation for black tea cultivation. Over the years, the Yuchi Branch of the Tea and Beverage Research Station under Taiwan's Ministry of Agriculture has continuously worked on tea cultivar selection and improvement, leading to the development of the renowned **Yuchi Black Tea**. The subtle variations in terroir throughout the Sun Moon Lake tea region create a distinctive character that sets Sun Moon Lake Black Tea apart from black teas produced in other regions.
Premium Ruby Black Tea — A Signature Creation by Mr. Zhuang
Premium Ruby Black Tea is Mr. Zhuang's signature Ruby No. 18 black tea and the tea that has received the most awards in competitions.
