Cheongju

Cheongju , sometimes romanized as Chungju, is a clear, refined rice wine of Korean origin. The word cheongju (청주; 淸酒) consists of two characters: cheong (청; 淸) meaning "clear" and ju (주; 酒) meaning "alcoholic drink". It contrasts with takju (탁주; 濁酒), as "tak" (탁; 濁) means "turbid". The word takju usually refers to makgeolli (milky, unrefined rice wine). The hanja characters 淸酒 are the same as the kanji pronounced seishu used on the labels of sake.
