The name Brasserie du Flo originates from the locality located just in front of the town hall. At this place was a body of water, the size of which varied according to the seasons and which was called 'Le Flo'. The Confrérie de St. Antoine (Brotherhood of St. Antoine) has had its own beer brewed since 1978 (Cuvée St. Antoine Brune). The beer was brewed for years at Brasserie du Bocq in Purnode and then at the Van Steenberge brewery in Ertvelde. In December 2002 a private microbrewery was established in the former town hall of Blehen.

After being at a standstill following the explosion of a tank in 2017, a new project (still under the wings of the Confrérie de St. Antoine) is being set up where the quality and the didactic aspect are put forward. A young team of enthusiasts will invest in modern equipment to relaunch the brewery.
