The invention provides a combined processing method of tea wine. The tea wine is prepared by carrying out mixed fermentation on a tea leaf extracting solution and a grain saccharification solution. The combined processing method comprises the following steps: firstly, extracting tea leaves, thus preparing the tea leaf extracting solution; secondly, mixing sorghum, rice and corn according to a certain proportion, smashing, cooking, saccharifying, mixing the obtained grain saccharification solution with the tea leaf extracting solution, adding koji, and forming a tea leaf fermenting solution through liquid fermentation; finally, sterilizing, blending, fining, filtering, ageing and carrying out secondary filtration, thus obtaining the tea wine. The tea wine prepared by the method provided bythe invention has the characteristics that a product has strong tea fragrance, soft-sweet and mellow taste, coordinated smell, long after taste and the like; compared with traditional tea wine, the tea wine adopts the tea leaf extracting solution and the grain saccharification solution of the sorghum, the rice and the corn for common fermentation, so that functional activity components in the tealeaves are retained to the maximum; meanwhile, base wine blending is carried out after fermentation, the disadvantages that fermented wine is low in alcohol degree and distilled wine is complicated intechnology and spicy in taste are overcome, softness of tea and rigidity of wine are completely combined, and the varieties of tea leaf and wine products are enriched.
