The time of the historical origin of liquor
In addition to the introduction of distilled liquor, the wine industry also tried to steam grain liquor and achieved success, so people brewed grain shochu. Of course, when shochu originated has always been controversial, but judging from the law of historical development, the definitive historical records are limited to the Yuan Dynasty. Due to the Mongolian expedition to Central Asia, West Asia and Europe to explore Wan Li, the western distilled liquor method spread to Middle China and was used by people.
Most people who think that shochu originated in Han and Tang Dynasties don't understand the historical development of liquor. They only saw the names of "shochu" and "liquor" in ancient books, and speculated that distilled liquor was produced in China before the Yuan Dynasty. This is an unscientific conclusion. The noun meaning of "shochu" takes the Yuan Dynasty as the dividing line, which is different from that of "shochu" before the Song Dynasty. Both of them refer to grain fermented wine which has been heated at low temperature.
