Abstract

The invention discloses a dendrobium-candidum-stem black tea and a preparation method thereof, and relates to the technical field of tea preparation. The preparation method of the dendrobium-candidum-stem black tea comprises the following steps: S1, taking a certain amount of a dendrobium candidum stem composition, wherein the dendrobium candidum stem composition is composed of pretreated tea leaves, dendrobium candidum stems and divaricate velvetplant roots and rhizomes, and rolling the dendrobium candidum stem composition under the condition of a relative humidity of 85-90% for 40-84 minutes; S2, fermenting the rolled dendrobium candidum stem composition at a temperature of 25-30 DEG C and a relative humidity of 80% or above for 3-5 hours; and S3, stir-frying the fermented dendrobium candidum stem composition in a pan at 110-120 DEG C for 5-8 minutes, carrying out cooling, carrying out stir-frying at 60-65 DEG C until the water content is 80-85%, carrying out baking at 85-90 DEG C for 60-120 minutes, and carrying out baking again at 110-120 DEG C for 5-7 minutes so as to obtain the dendrobium-candidum-stem black tea. Health-caring functions of the dendrobium candidum stems can begiven full play by the dendrobium-candidum-stem black tea; moreover, the dendrobium-candidum-stem black tea has aromatic and mellow taste.
