The invention discloses a production method of oolong
black tea. Preparation of the oolong
black tea in a fine day comprises following steps of picking four-leaf and one-
bud tea leaves of a oolong tea species, sunning the tea leaves, shaking the tea leaves, airing the tea leaves, rolling, completely fermenting, pressing with a
machine, wrapping and twisting for 2-3 times, baking, and forming a finished product; and the preparation of the oolong
black tea in
overcast and rainy days comprises following steps of picking the four-leaf and one-
bud tea leaves of the oolong tea species, airing the tea leaves, shaking the tea leaves, airing the tea leaves twice, rolling, completely fermenting, pressing with the
machine, wrapping and twisting for 2-3 times, baking, and forming the finished product. The production method takes the four-leaf and one-
bud tea leaves of the oolong tea species as a
raw material, and the prepared finished black tea is uniform in forming, so that a yield of tea trees in unit area and a utilization ratio of the tea leaves are increased effectively; in addition, the finished black tea produced by the production method under different weather situations is smaller in taste difference; and finally, the black tea prepared by the production method is suitable for high-temperature
brewing at 90-100 DEG C, and an
aroma difference between the finished tea and the existing black tea is very small.
