According to the fragrance characteristics of flowers, jasmine belongs to the "temperament flower", that is, flowers only release aroma during the flowering process, while immature buds and flowers with a long opening time have a weak aroma and cannot be used for tea. The jasmine flowers used to make flower tea are generally picked in the midsummer afternoon, when the temperature is high, the sun is sufficient, the flowers are plump, heavy, and the aroma is at its highest. Longdu jasmine tea is produced in Hengxian County, Guangxi, and is made on the same day after picking to ensure a full floral fragrance. The price of Longdu jasmine tea is relatively close to the people as a whole, and self-drinking tea is generally packaged in simple bags, with specifications ranging from 50g to half a catty, and the price is within 100 yuan. The high-end drifting snow series uses early spring buds, the freshness of the tea soup is higher, and an appropriate amount of petals is added as a foil, and the price of 50g is 45 yuan.
