The founder of the Belgian design company Extremis, Dirk Wynants, asked Rudi Ghequire (Rodenbach's brewmaster) to create Saison Tremist as a house beer. It's brewed at Kazematten Brewery, within the 17th-century fortifications of the city of Ypres. Extremis and Kazematten partner with the St. Bernardus Brewery to bring the beer to an international audience.
