Abstract

The invention relates to a preparation method of agilawood oolong tea, which comprises the following steps: (1) withering: collecting mature leaves of agilawood trees, and withering for 1-2 hours under the conditions that the relative humidity is 50-70%, the wind temperature is 35-40 DEG C and the wind speed is 3.4-5.4 m / s; (2) rocking of green leaves; (3) fixation: performing fixation at 200-230 DEG C for 10-15 minutes, and then immediately spreading the leaves under the conditions that the wind temperature is 20-25 DEG C and the air speed is 0.3-1.5 m / s; (4) rolling, wherein the first rolling pressure is 100-130 N, the rotating speed is 20-30 rpm, the second rolling pressure is 300-350 N, and the rotating speed is 5-8 rpm; and (5) drying: primarily drying at 100-130 DEG C for 1-2 hours, after spreading for cooling, re-drying under the re-drying condition that the temperature is raised to 90-95 DEG C at the rate of 5-7 DEG C from 60-65 DEG C, and preserving heat for 0.5-1 hour. The agilawood oolong tea prepared by the method disclosed by the invention is tight in appearance, oily and uniform in color and luster, golden, clear and bright in soup color, fresh and refreshing in fragrance, mellow in taste, sweet in aftertaste and fleshy, soft and bright in leaf quality, and the sensory score reaches 90 points or above. Compared with other samples, the agilawood oolong tea has fresh and cool brand-new fragrance and is excellent in appearance, color, luster, taste and leaf bottom.

Description

technical field [0001] The invention belongs to the technical field of tea processing, and in particular relates to a preparation method of agarwood oolong tea.
