The process of first feeding production is the so-called "Xiasha" in the production of Maotai-flavor liquor. "Xiasha" includes six working procedures: moistening sand, cooking, spreading and cooling, adding koji, stacking and fermentation in pits.

The second feeding is to add new sorghum according to the ratio of 1: 1 and continue cooking in retort. After spreading and cooling, add distiller's yeast, collect and ferment, and then enter the cellar. The first two cooking materials do not take wine, just to increase fermentation time and intercept more microorganisms.
