In the production process of Wuliangye liquor, the four-word secret of "brewing, selecting, aging and blending" was summarized and refined. Its ancient winemaking pits began in the first year of Hongwu in Ming Dynasty (1368), and active winemaking has continued to this day.

Wuliangye has inherited the history of solid-state brewing for more than 1000 years, and it has been brewing with multiple grains since the prosperous Tang Dynasty. In the first year of Tang Yongtai (765), Du Fu, a great poet, passed by Yibin, and Yang, the local governor, gave a banquet in the East Building, and entertained him with heavy blue wine. Du Fu was amazed after drinking, and wrote "Rongzhou Yangdonglou Banquet": "The victory is amazing, and the feelings are forgotten." From a geisha, I am very happy to be the master. Spring wine is heavy and litchi is light red. The building is high and melancholy, and the flute has not stopped. "In the third year of Jianzhong (782), Chongqing Bijiu officially became the official custom-made wine (county brew) by the imperial edict of Tang Dezong.

In the Northern Song Dynasty, Da Shi Yao in Yibin opened Yao's Brewery. On the basis of heavy blue wine, after repeated attempts, he brewed "Yao Zi Xue Qu" with sorghum, rice, glutinous rice, buckwheat and millet and local Anle spring water. Born five years younger (1098), writer Huang Tingjian worked as a driver in Fuzhou and lived in Rongzhou (now Yibin). He made friends with many local celebrities, drank and laughed, and wrote a "Happy Spring", praising Yao's song: "Yao's song, cups compete for jade. Tang Yu, a native of Bai Yunsheng Valley. Clear but not thin, thick but not turbid. Sweet without stinging, spicy without stinging. I have a good hand, so I need this medicine. At a loss, upside down. "

At the beginning of the Ming Dynasty, the Chen family founded Wendengfeng Winery, which combined the essence of Yao Zi's learning songs, and replaced the corn in the original five-grain formula with the newly imported corn from overseas at that time, and finally formed a more perfect "Chen formula".

At the end of the Qing Dynasty, Deng Zijun inherited the "Wendeng Peak" restaurant and changed its name to "Li Chuanyong"; In the year of Xuantongyuan in Qing Dynasty (1909), Deng Zijun took wine to the banquet of local celebrities. Yang Huiquan, a juren in the late Qing Dynasty, tasted it and said, "Such a good wine is called miscellaneous grains wine, which seems a little vulgar. Although Yao's song title is elegant, it is not enough to reflect its charm. Since this wine is the essence of Wuliangye, why not change its name to Wuliangye? " Say that finish for it, Deng Zijun readily adopted. Since then, "Wuliangye" has been officially named.
