Du Kang (Chinese: 杜康; pinyin: Dù Kāng), also known as Shao Kang, is the inventor of fermented drink in Chinese legend, and the deified patron of winemakers in China and Japan (Tōji). Wine, or more precisely, Chinese alcoholic beverages are widely known as an important part of the ancient Chinese rites and the court culture. Their invention is not attributable to a single person, and perhaps not even a single deity. Du Kang is sometimes reported as a minister of the Yellow Emperor, being more of a cultural symbol than a historical personality.
It is unknown where and when and if Dù Kāng actually lived; the dates in ancient sources range over thousands of years, Eastern Zhou dynasty to the Xia Dynasty. In the Shuowen (2nd century AD) the name is identified with Shaokang, the sixth ruler of the Xia. Du Kang's story is referenced in Cao Cao's poems of the 3rd century. Since Cao Cao, Du Kang is used as a metonym for good wine. Ruan Ji references Du Kang in his attributed guqin piece Jiukuang. Presently it is a famous wine brand in PRC.
