Baijiu or shaojiu is a Chinese liquor. It is usually sorghum-based, but some varieties are distilled from huangjiu or other rice-based drinks. All typically have an alcohol content greater than 30% and are so similar in color and feel to vodka that baijiu is sometimes known as "Chinese vodka". There are many varieties, classified by their fragrance, but most are only distilled once, permitting stronger flavors and scent than vodka. The prestige brand within China is the "sauce-scented" Moutai or Mao-t'ai, produced in the southern city of Maotai in Guizhou. More common brands include Luzhou Laojiao, Wuliangye and varieties of erguotou.
