For thousands of years, this skill has been passed down from generation to generation through word of mouth, and it has been continuously innovated and developed. It still plays an irreplaceable key role in the process of modern Fenjiu brewing.
1932 Mr. Fang, a famous expert in microbiology and fermentation in China, summed up the brewing technology of Fenjiu as "seven secrets", namely, "people must be refined, water must be sweet, koji must be timely, sorghum must be true, pottery must be clean, and fire must be delayed". Fenjiu is a model of Fen-flavor liquor and the originator of China liquor. Many famous wines in China, such as Maotai, Luzhou Daqu, Xifeng and Shuanggou Daqu, have borrowed from the brewing technology of Fenjiu.
