Description

technical field [0001] The invention belongs to the technical field of tea processing, and in particular relates to a processing method of Laocong-flavored white tea. Background technique [0002] Laocong Narcissus is one of the four famous congrues in Wuyi rock tea. The leaves of Laozong Narcissus tea are soft and rich in nutrients. The taste of green moss, moss and brown rice are very popular among people. Laocong narcissus is generally picked from narcissus tea trees over 50 years old. The variety is relatively scarce and the output is low, and the price is high. In recent years, with the promotion and application of high-flavor tea tree varieties, combined with white tea processing technology, the products processed into new varieties of white tea are gradually increasing. The white tea produced by this method has a unique fragrance, which allows more nutrients to be retained. However, there are very few reports on the processing methods of Laocong-flavored white tea, w...
