The water quality of the Ailan Plateau, located on the western side of Puli Township, Nantou County, is pure and sweet. Because of the water's unique qualities, it is considered the primary "Shaoxing wine spring." Made by fermenting glutinous rice, Penglai rice, wheat, and other ingredients, the golden yellow Shaoxing wine has a dry, sweet taste. Kinmen, with its hot, dry weather and unpolluted environment, is the best place to make Gaoliang spirit. Thanks to excellent water quality, the Gaoliang produced here is superior in quality and fine in taste. In Matsu, with the uniqueness of the local spring water, brews such as Daqu, Gaoliang, and Matsu Old Wine are most popular. Clear ruby-colored Matsu Old Wine is not just a favored drink on Matsu, but is also widely used in Chinese cooking.
