The Brussels Gueuze Museum was founded in 1978. This association was founded on the initiative of Jean-Pierre Van Roy, supported by several friends. The goal pursued by the master brewer was simply to avoid the disappearance of Brasserie Cantillon.

It is worth knowing that spontaneous fermentation and its derivatives, so sought after and appreciated today, were then old-fashioned beers. So it was about protecting and promoting the brewing tradition that flourished at the beginning of the 20th century.

Cultural measures were used to achieve this goal: guided tours, exhibitions, public breweries, the use of historic buildings and equipment that are still in use. The Cantillon Brewery has become a living museum and it is thanks to the Brussels Gueuze Museum that it has gained a reputation beyond borders.
