[Method] After the activated wine yeast was added to the apple juice by sizing classification, rinsing, falling to pieces and squeezing, the preceding fermentation began. Every other day, parameters of fer- mentation broth such as temperature, pH, acidity, sugar content and bubble nurdbers were detected. Once the sugar content of the fermentation suspension was approaching 5 -6 °Bx, the following fermentation would start via pouring wine. After 20 -30 days, the cider was changed into origi- nal apple brandy by distillation. The last procedure was aging which included man-made speediness aging and oak wood aging about 20 days. The physical and chemical compositions before and after aging were measured. [ Result] 22.5 kg apple resulted into 16.56 L of juice. The juice yield was about 73.6% （10 ml/kg）. The alcohol rate of distilled apple juice was 20.0%. The color of apple brandy was darker than that of original apple brandy. Alcohol level reduced, but total acidity, fixed acid, lipid and furfural content rose. [ Conclusion] The apple brandy was of particular flavor and high quality by selecting befitting fruit, activated wine yeast and feasible brewing, distillation and aging technology. It will be conductive to the development of apple processing industry and the research and development of key brandy technique.展开更多
