Kooksoondang () is a South Korean brewery, founded in 1952. The name translates in English to "house of good yeast and wines."

Kooksoondang is a major producer of natural beverages and health-related products. In 1994, Mr. Jung-Ho Bae, CEO of the company, revamped the benefits of a traditional wine Koreans have been enjoying for many years, mixing modern technology with an original recipe, and produced Bek Se Ju.

The drink has a unique fermentation method for the brewing of rice wine. Unlike the regular methods of producing rice wine, Kooksoondang grinds raw rice with nuruk (Korean traditional fermentation starter) and brews them without steaming.

Kooksoondang Brewery has been involved in exporting since 1994, and in 2003, the company took over Haitai & Company. The company's current president is Bae Jung Ho.

Kooksoondang has been exported to over 35 countries around the world.

The export volumes reached over $5 million in 2005.

In Canada, the main distributor is CoBees Enterprise Ltd., which is located in Port Moody, British Columbia.
