Who was the first person to make wine? Is it Du Kang?

The earliest brewer was not Du Kang, but Yidi.

There is such a record in the Warring States Policy: Once upon a time, the emperor's daughter ordered Yidi to make wine beautifully, and when she entered Yu, Yu drank it and was willing to drink it. She said, "There will be countries that drink in the future." So, I gave up my manners and gave up my wine. Simply put, it is to entrust Yidi to invent wine and give it to Yu. Although Yu feels delicious, it is bound to bring disaster to the country and the people, but it alienates Yidi.

The sayings of "Yidi Brewing" and "Du Kang Brewing" are somewhat mythical. Like other great inventions in ancient China, the invention of wine was never completed by one or two people. In our country, grain wine is the main wine, which is a bit unfavorable. Grain wine is not as convenient as fruit wine: fruit wine is produced by yeast fermentation existing in nature; Grain wine is much more troublesome. Starch in grain must be hydrolyzed into sugar before it can be turned into wine. It must be saccharified before it can be alcoholized. The original wine is probably that the grain germinates and deteriorates without being preserved, and then it is boiled-turned into a natural distiller's yeast, and then used to make wine; There is a record in the history books that distiller's yeast is used to make wine: making wine is just a tiller. According to the current archaeological evidence, a large number of traces of wine vessels and brewing workshops have been found in the Shang Dynasty site in Taixi, Gaocheng, Hebei Province: "8.5 kilograms of yeast remains were unearthed in the remains of Taixi brewing workshop site, which was identified as artificially cultivated koji yeast by experts from Chinese Academy of Sciences."
