The invention discloses a
processing method of fermented
black tea. The
processing method comprises the following steps of performing withering; performing empty twisting, wherein the pressure is 0N during empty twisting; performing heavy twisting: spraying complex
enzyme fluid while performing twisting during heavy twisting, wherein the twisting pressure is 70-120N; performing light twisting, wherein the twisting pressure is reduced to 20-30N during light twisting; performing water surface
fermentation: performing
fermentation in a fermenting box made of Chinese birch wood materials during the water surface
fermentation, during fermentation, laying a gauze which is wet by being soaked in
sterile water at the bottom of the fermenting box, placing twisted leaves on the gauze, performing covering with a fermenting cover, placing the fermenting box in flowing
warm water of 25-35 DEG C, performing fermentation for 4-6h, and conveying the
fermented tea leaves into a
drying box; and performing
drying: performing
drying in the drying box so as to obtain finished products. According to the
processing method disclosed by the invention, a twisting working procedure and a fermentation working procedure are optimized, so that the rupture rate of
cell walls is further enlarged, more tea liquor and
tea leaf inclusions flow out, the fermentation effect of the tea leaves is guaranteed, after being brewed, the made
black tea is attractive in soup color, mellow in mouth feel and sweet after taste, and the fermented
black tea is highest-grade black tea among all of the black tea.
