The Jin Guanyin tea plant was originally cultivated by the Tea Research Institute of the Fujian Academy of Agricultural Sciences through hybrid breeding, using Tieguanyin as the female parent and Huangyan as the male parent. In 2004, this tea plant was introduced to Longquan City, Lishui, Zhejiang Province for trial cultivation, and under the guidance of experts from the Department of Tea Science at Zhejiang University, a high-quality Jin Guanyin black tea was successfully developed.
Longquan City, located in the southwest of Zhejiang Province, boasts unique natural conditions, including a suitable climate, fertile soil, and ample rainfall, making it an ideal place for planting Jin Guanyin.
In terms of product characteristics and craftsmanship, Jin Guanyin black tea has a tightly coiled and substantial appearance, resembling a screw in shape, with a deep green and fresh luster. The tea liquor is a bright honey green color, with a rich and long-lasting aroma, and a taste that is fresh, mellow, and thick. The leaves at the bottom are soft, even, and bright green. These features not only make it visually appealing but also provide a rich tasting experience.
Regarding its physicochemical indicators, Jin Guanyin black tea has a moisture content of ≤7.0%, a water extract content of ≥36%, tea polyphenols ≥9%, caffeine ≥2%, and amino acids ≥2%. These figures indicate its high-quality composition.
