What is "cheongju"

Cheongju is the capital and largest city of North Chungcheong Province in South Korea.

Cheongju (청주 , literally "clear wine" or "clear liquor") is a clear Korean rice wine. There are various local variations, including beopju, which is brewed in the ancient city of Gyeongju.

For cooking, Hi Soo Shin Hepinstall recommends a dry white vermouth as a substitute if cheongju is unavailable.
