Description

Technical Field

[0002] Tea extraction is a beverage preparation process in which tea leaves are soaked in cold water and the tea liquid is slowly extracted. It is named because its production process is similar to the process of leaching gold from metal, and is likened to "extracting" the essence of tea from tea leaves. Compared with traditional hot brewed tea, tea extraction has a more refreshing taste and pure tea soup color, and will not bring out the bitter components in the tea leaves.
