Description

A kind of glutinous rehmannia leaf tea and preparation method
Technical field
A kind of glutinous rehmannia leaf tea of the present invention and preparation method, belong to the manufacturing technology field of tea substitute.
Background technique
There is very long record of drinking tea on Chinese history, tea is the drink of the whole nation of the Chinese nation, and hair is heard in the legendary god of farming in Shandong week Public affairs, it is emerging to be contained in the Song Dynasty the Tang Dynasty, when being popularized in Ming and Qing.Drinking tea not only becomes inseparable a part in people's life, The cultural connotation and ceremony for more passing through the habit and China such as infuse tea, appreciate tea, hear tea, drink tea, sample tea combine a kind of tool to be formed There is a kind of cultural phenomenon of distinct Chinese culture feature.
