According to different production methods, it can be divided into three categories, namely, liquid liquor, semi-liquid liquor and solid liquor. In solid-state liquor, it can be divided into four categories according to the size of koji blocks: Daqu liquor, Xiaoqu liquor, mixed liquor of big and small koji and bran koji liquor. Daqu liquor refers to liquor brewed with Daqu, such as cellar liquor, Shuanggou Daqu, Guiyang Daqu, Yanghe Daqu and so on. Xiaoqu liquor is made of rice and wheat as raw materials, and some medicinal materials are often added in koji making, so it is also called "medicinal koji" or "medicinal liquor". The amount of Xiaoqu used in brewing is small, only 1% or 2% of the raw materials. Bran koji is a koji-brewed wine made from bran.
