Along with the scotch-producing areas in Scotland, and the cognac-producing areas in France, Suqian is counted as one of the three main wetland liquor-producing regions of the world. The region is located between the Huai River and Hongze Lake in the ancient town of Shuanggou. It is known as the birthplace of Chinese liquor.
Suqian enjoys a warm and moist climate. Deep red and slightly acidic, its loamy soil is full of organic matter and has hundreds of types of micro-organisms that are beneficial to the human body. The soil excels at maintaining heat and moisture, and contains a type of bacillus that spurs the production of matter essential to the fermentation process—Clostridium difficile. This type of soil is ideal for pit cellars—fermentation tanks in this environment produce spirits that are both sweet and fragrant.
In 2012, the Chinese Federation of Light Industry and the Chinese Liquor Association granted Suqian the title “Chinese Capital of Spirits”.
