Heating distillation. Because the boiling point of alcohol is lower than that of water, alcohol will start to steam first, and the way to make the temperature of small pot of wine higher is heating distillation. The evaporated alcohol gas is collected and condensed to obtain the wine with higher degree. The process of making wine in a small pot is divided into two steps: covering rice and baking wine. After the above two steps are completed, add boiling water to boil, so that the strong steam rises, and the alcohol in the wine rice is distilled out, rising to the bottom of the cauldron, quickly condensing into wine liquid, dripping into the wine leakage, and then flowing into the wine storage pool along the wine guide bamboo tube.
