Embodiment 1

[0016] Embodiment 1, a kind of preparation method of bar-shaped Keemun black tea comprises the steps:

[0017] Step (1) Picking: picking tea leaves of stored leaf species, the tea leaves are selected from fresh buds and leaves with one bud and one leaf, one bud and two leaves at the beginning of development, and one bud and two leaves;

[0018] Step (2) Withering: Put the fresh buds and leaves picked in step (1) into the withering machine and wither until the water content drops to 55%; when withering: the thickness of the leaves is 12, the amount of leaves is 9kg / ㎡, and the withering temperature is 15°C , withering time 8, leaf turning frequency 2h / time.

[0019] Step (3) Kneading: Knead the withered buds and leaves successively for 45 minutes with air pressure, for the first time with light pressure for 15 minutes, for the first time with loose pressure for 5 minutes, again with light pressure for 10 minutes, and again with loose pressure for 8-10 minutes, until the cell cru...
