Scented tea is made by placing green tea and jasmine flowers together and scenting them many times. This is a unique tea variety in my country. The tea is named after the flower, and the flower is better because of the tea. Scented tea originated in the Song Dynasty, began in the Ming Dynasty and became popular in the Qing Dynasty. In the Qing Dynasty, many tea houses in Beijing were famous for selling jasmine tea. In the late Qing Dynasty, Zhang Changyi opened Zhang Yiyuan Tea House, which was passed down from generation to generation and specialized in making and selling jasmine tea. During the Republic of China, Zhang Yiyuan was famous in Beijing. Frequent customers of bathhouses and theaters almost always asked for Zhang Yiyuan when drinking tea. Peking opera masters Qiu Shengrong, Ma Lianliang, Tan Fuying and others were also Zhang Yiyuan's old customers. After the public-private partnership in 1956, Zhang Yiyuan gradually lost its original characteristics of specializing in the sale of scented tea. In 1992, Zhang Yiyuan's traditional jasmine tea production process was restored. When making Zhang Yiyuan jasmine tea, Fujian roasted green tea spring tea is used as the tea base. The initial production process mainly includes withering, killing green, rolling, baking and other processes. This kind of scented tea, which is loved by the people of Beijing, has a unique flavor, is of good quality and low price, contains a deep cultural heritage of old Beijing, and has a wide market. However, the production technique of Zhang Yiyuan jasmine tea is relatively complicated and the manual labor is quite hard, so fewer and fewer people are willing to learn this technique. The inheritance and development of scented tea making technology has become an urgent problem to be solved.
