Abstract

The invention discloses a preparation method of strip-shaped black tea, and relates to the technical field of black tea preparation. The preparation method comprises the following preparation steps: 1) picking fresh leaves: picking and selecting fresh leaves with one bud and one leaf and fresh leaves with one bud and two leaves as tea leaf raw materials; 2) performing withering: putting the pickedtea leaves into a withering tank for graded heating withering; 3) performing rolling: rolling the withered tea leaves in a rolling machine until the tea leaves are rolled into strips; 4) performing fermentation: putting the rolled tea leaves into a fermentation machine for fermentation; 5) performing drying: drying the fermented tea leaves; 6) performing aroma enhancement: standing the dried tealeaves, enhancing aroma, and performing spreading for cooling so as to obtain the strip-shaped black tea. According to the preparation method disclosed by the invention, a graded heating withering manner is performed, and physical and chemical reactions are strictly controlled through different gradient blast heating manner, so that the prepared black tea is compact and bent in appearance, hair-exposed, black and smooth in color and uniform, and besides, the black tea is high in freshness and sweetness in internal texture sense, fresh, mellow and sweet in taste, red and bright in soup color and uniform, soft and tender in leaf bottoms.
