Liquor, also known as shochu, tempting fate and burning knives, is one of the six largest distilled spirits in the world. Liquor has a compound flavor with esters as the main body. It is made by using koji and yeast as saccharifying and fermenting agents and starch (sugar) as raw materials through cooking, saccharification, fermentation, distillation, aging and blending. Strictly speaking, the blended wine made of edible alcohol and edible spices can't be regarded as liquor. Liquor is mainly concentrated in the upper reaches of the Yangtze River and the triangle of Renhuai in Guizhou, Yibin in Sichuan and Luzhou in Sichuan in Chishui River basin, with sauce-flavor and Luzhou-flavor types.
