The "Bi Lv Chun" brand Chinese Liquor uses two kinds of raw materials: Northeast pure high-quality sorghum, and medium and high temperature nuggets made from wheat, barley, and peas as fermentation agents for two-wheel fermentation. The construction of the cellar pond is made of old cellar mud from the old factory in 1958, and it is built into small cellar ponds. The cellar ponds are protected by the most advanced high-quality biological strains in China to make the cellar cells richer in bacteria.
