There are generally three kinds of wine. Every time a pot of wine is burned, the wine that begins to flow out is called "pot head". The concentration of this kind of wine is relatively high, which can reach more than 75 degrees, and then the concentration keeps decreasing, and the wine that can be drunk later is only 10 degrees, which is called "liquor strategy". The raw materials of shochu can generally be fermented and put into the pot for five or six times. In addition to wheat, sorghum, corn and other raw materials, there are corn stalks, corn kernels, wheat bran, rice bran and other accessories. After crushing according to a certain proportion, add water, steam, add yeast, stir evenly, and then enter the cellar for fermentation. It usually takes 5 days to make wine out of the cellar. This is the first pot. After the wine is discharged, the materials in the steamer should be taken out, cooled loosely after fermentation, and then a small amount of new raw materials and yeast should be added, and then stirred evenly before fermentation in the cellar to complete the work of one shift. After 5 days, take out the shochu, which is the second pot. At this time, the wine that began to flow out is the real "Erguotou". As the name implies, "Erguotou" is the "Guotou" wine when the second pot of raw materials is fired. This wine is the purest, odorless, high in concentration but not strong, and really mellow. If only 60-degree wine is taken, sealed underground and aged for a long time, the taste of the wine will be better. This is the famous "cellar wine".

1949, after the founding of New China, Beiping Liquor Branch of North China Liquor Monopoly Corporation, the predecessor of Beijing Sugar, Tobacco and Liquor Company, immediately set up a factory to produce Erguotou liquor. Erguotou wine is made from sorghum as raw material or bran koji and yeast as saccharifying and fermenting agents, by adopting the traditional "Old Five Increasing Wax" process, steaming raw materials and auxiliary materials, entering the pool at low temperature, fermenting properly, slowly steaming, pinching the head and removing the tail, and aging. Erguotou liquor is widely recognized by consumers because of its clear and transparent body, fragrant, mellow, sweet and refreshing taste, strong alcohol power, long stamina and long aftertaste, and its brand family is increasingly rich.
