The invention relates to a preparation method of 
xanthoceras sorbifolia 
black tea. The method comprises the following steps that 1, water removal is carried out, a 
machine is adopted for water removal, when the pot temperature reaches 280 to 300 DEG C, 5 to 10kg of 
xanthoceras sorbifolia fresh leaves are put into a pot, the pot temperature is regulated according to the 
moisture content of the fresh leaves for carrying out stuffy stir-frying or shaking stir-frying, and the 
xanthoceras sorbifolia leaves can be taken out from the pot after the water removal is carried out for 1 to 3 minutes; 2, primary kneading is carried out, a kneading 
machine is adopted, the rotating speed of the kneading 
machine is 40 to 60 revolutions / minute, the kneading time is 10 to 30 minutes, and kneading can be completed after the xanthoceras sorbifolia leaves become strips or the 
skin drapes; and 3, 
pile fermentation is carried out, the primarily kneaded tea base is immediately piled up without treatment, the piling height is about 0.7 to 1.2m, a heat insulation cotton cover is covered, the 
room temperature is maintained at 25 DEG C to 32 DEG C, the 
relative humidity is maintained at 75 percent to 90 percent, the piling up lasts 24 to 36 hours, water beads can occur on the surfaces of the tea base, the leaf color is changed from dark green to yellow brown, the tea base has slight 
vinasse flavor or sour 
flavor, the hand can feel the heat after extending into the tea 
pile, the stickiness of the tea groups is reduced, and the 
processing is completed after the tea groups can be scattered after being hit. The method provided by the invention has the characteristics that the method is simple, and the cost is low.
