The invention provides a making method of kaoliang spirit. Different the traditional brewing method of gaoling sprit, which uses gaoling grains as raw materials, the method which uses sweet kaoliang peduncles and kaoliang leaves as raw material to brew kaoliang spirit by the steps of squeezing, coarse filtration, fine filtration, sterilization, strain inoculation, fermentation, drum change, sterilization, storage, mixed blending, filtering, bottling, and the like or by directly carrying out the steps of distillation, filtering for turbidity removal, storage, blending, bottling, and the like after the fermentation process; in addition, fuel alcohol can be prepared by carrying out reextraction after the distillation process. In the invention, since the sweet kaoliang peduncles and the kaoliang leaves are used as the raw materials, the step that grain starches are fermented into sugar and then transformed into alcohol is avoided, thereby simplifying the steps and saving the consumed working hours; in addition, the raw materials can be obtained in shortened period, suitable for intercropping, crop rotation and continuous cropping, and produced defective materials can be used as livestock feeds; and besides, the prepared kaoliang spirit is different from kaoliang spirits prepared from grains in flavor.
