Duivels Bier is a dark beer of high fermentation. It is the town beer of the city of Halle. Traditionally, every year the beer is given for free to inhabitants of the city during Carnival.
In his early twenties, Frank Boon fell under the spell of a beer style known as Oude Geuze. It was his ambition to take over ‘geuzestekerij De Vits’ in Lembeek. The roots of this brewery date back to 1680, but René De Vits had no successors. In 1975 Frank started in a cellar in Halle with the production of Geuze.
