Oolong Tea, also known as Qing tea, gets its name from the red edges and green centers of its leaves after brewing. As a unique category of tea in China, Oolong tea enjoys a high reputation domestically and is popular worldwide. So, what type of tea is Oolong tea exactly? What are its unique benefits and varieties? Let's uncover the mysteries of Oolong tea together.
Oolong Tea: Definition and Classification
Oolong tea, also known as Qing tea, is a partially fermented tea. Its uniqueness lies in its fermentation level, which falls between that of green tea (unfermented) and black tea (fully fermented). The process of making Oolong tea includes picking, withering, shaking, stir-frying, rolling, and baking. Due to different levels of fermentation, Oolong teas have distinct flavors, some being light and delicate, others rich and full-bodied.
Oolong tea can be categorized into several main types: Tieguanyin from Anxi, Wuyi rock tea (such as Dahongpao), Dancong from Guangdong, and Taiwanese high mountain Oolong. Each has its unique flavor profile and production techniques. For example, Tieguanyin is renowned for its orchid-like fragrance and sweet taste, while Dahongpao is known for its strong mineral notes and robust flavor.
