In accordance with the ancient, traditional and authentic way of brewing Baijiu, which is using only one kind of grain as raw material, Luzhou Laojiao has always been using the grain of supreme quality consistently for brewing --- the organic red glutinous sorghum, which grows only in the south Sichuan, so that the Baijiu will become more pure and mellow. The sorghum grown on purple soil in the south Sichuan is red and bright in color, full in grain, free from impurities and pure in texture. The starch is mostly amylopectin, with certain tannin content, strong water absorption and easy gelatinization.
