The process of making jasmine tea in Fuzhou is a traditional process of making scented tea by using special process to shape tea or refined green tea base with jasmine flowers. Fuzhou is located in the subtropics, with mild climate and abundant rainfall. The natural conditions are very suitable for the growth of jasmine, and it has a history of jasmine cultivation for more than 2,000 years. As the birthplace of jasmine tea, the process of making jasmine tea in Fuzhou has a history of nearly a thousand years. Many historical materials of the Song Dynasty recorded the process of picking, making and tasting jasmine tea in Fuzhou. During the Xianfeng period of the Qing Dynasty, Fuzhou jasmine tea began to be produced on a large scale as a royal tribute tea. The process of making jasmine tea in Fuzhou must go through more than ten traditional process procedures, including tea base processing, fresh flower maintenance, scenting flower blending, stacking, heat dissipation, collecting piles, picking flowers, baking, cooling, rotating scenting or jacquard, leveling piles, and packing. Among them, the fresh flowers exuding fragrance and the tea leaves absorbing fragrance are the main processes of jasmine tea scenting, and the scenting and splicing of flowers are the key steps in the production process. The fresh jasmine flowers exude fragrance through biochemical changes. Mature jasmine flowers decompose aromatic substances under the action of enzymes, temperature, water, oxygen, etc., and continuously exhale fragrance as the flowers open with physiological changes. The tea leaves absorb fragrance under the action of physical adsorption. While absorbing fragrance, they also absorb a large amount of water. Due to the penetration of water, chemical adsorption occurs. Under the action of moisture and heat, complex chemical changes occur. The tea soup gradually changes from green to bright yellow, and the taste changes from light astringent to rich, forming the unique fragrance, color and taste of scented tea. The scenting process of Fuzhou jasmine tea has a long history, and its process is mature and has high practical value. The fragrance of jasmine flowers is overflowing during the scenting process, making the fragrance of jasmine a cultural landscape with regional characteristics; its product, Fuzhou jasmine tea, not only maintains the rich and refreshing natural tea flavor of green tea, but also contains the fresh fragrance of jasmine flowers, with a yellow-green color and a golden and clear soup color, which has a high appreciation value and economic value.
