Kaoliang or sorghum wine is a strong distilled liquor made from fermented sorghum. It is made and sold in both Taiwan and mainland China, and also popular in Korea, where it is called goryangju (hangul: 고량주; hanja: 高粱酒) or bbaegal (which is originated from Chinese character 白幹). Kaoliang is an important product of the islands Kinmen and Matsu which are under the jurisdiction of Taiwan. Kaoliang ranges between 38 and 63 percent alcohol by volume.
金門高粱酒 (Hanyu Pinyin: jīnmén gāoliáng jiǔ) is one of the most popular brands of kaoliang in Taiwan. The name simply means 'Kinmen kaoliang' (jinmen/kinmen means Golden Gate). As the name indicates, it is produced on the island of Kinmen. The mainstays of the range are the standard 58 percent and 38 percent alcohol bottlings.
八八坑道高粱酒 (Hanyu Pinyin: bā bā kēngdào gāoliáng jiǔ) is produced by the Matsu Distillery on the island of Nankan, part of the Matsu archipelago. The name is derived from the name of an abandoned military tunnel which the distillery took over as storage space for their kaoliang and aged rice wine. It means "Tunnel 88 kaoliang". All of the distillery's aged kaoliangs are stored in the tunnel for at least five years.
