Since 1983, Dupont has produced a beer especially for a Gallo-Roman site near the brewery where Stone Age life is interpreted, the Archeosite d'Aubechies.
Known as Cervesia in Belgium this beer is a throwback inspired by research into the drinks of the Gallo-Roman era. It is surely one of the brewery's most exotic beers. It is a "Cervoise" beer spiced with a gruit (an old-fashioned herb mixture used to bitter and flavor beer, that was popular before hops came to predominate). Posca Rustica beer is highly, if delicately, spiced. Sweet woodruff (known as Galium odoratum or wild baby's breath) and bog myrtle are but two of about a dozen spices used. Posca Rustica has a unique, odiferous and spicy character. Bottle conditioned. Beguiling and unusual. Discover what beer tasted like when Belgium was ruled by the Roman Empire.
A mighty twelve Vanberg & DeWulf beers were named to the 2012 list edited by Chris Schonberger at Complex Media "100 Beers to Try Before You Die". One among them is Posca Rustica.
