Brouwerij Bosteels

Kwak beer is produced by the renowned Belgian brewery Brouwerij Bosteels, located in the town of Buggenhout, Belgium. The brewery was founded back in 1791 by Jean-Baptiste Bosteels and was managed by the family for seven generations before being acquired by AB InBev in 2016 (though production remains at the same historic site). In addition to Kwak, the brewery is world-famous for another legendary Belgian beer—Tripel Karmeliet.
