Brussels Museum van de Geuze

Brussels Museum van de Geuze is one of the most genuine beer destinations in Brussels — a working brewery, Cantillon, located in Anderlecht, where lambic has been produced through spontaneous fermentation for over a century. This isn't a re-created exhibit behind glass; it's an active production site dating back to 1900 that still brews beer using the same methods as when it opened.

How did this place come to be?

The Cantillon brewery was founded in 1900 by Paul Cantillon and his wife, Marie Troch. At the time, it was one of more than a hundred breweries producing lambic in Brussels — today it is the only one that has remained continuously operational. In 1978, then-owner Jean-Pierre Van Roy, together with a group of friends, decided to turn part of the building into a museum. The goal wasn't nostalgia but preservation: Van Roy wanted to safeguard a fermentation method found nowhere else in the world, at a time when industrial brewing was pushing traditional craft methods aside.

What makes this beer so unusual?

Lambic isn't brewed like ordinary beer — no cultivated yeast is added. In the Zenne valley, where Brussels sits, wild yeasts of the Brettanomyces family and other airborne microorganisms drift through the atmosphere. When they settle into the open cooling vessels in the brewery's attic, they trigger spontaneous fermentation. The process is so weather-dependent that brewing can only take place in winter. The resulting lambic is aged and blended across different vintages in oak barrels to produce geuze, while the brewery also makes faro and kriek.

What will visitors see?

The tour moves through the rooms of a real, functioning brewery: the brewing hall, the fermentation vat room, the malt lofts, the rooftop cooling vessels, the storage area for wooden barrels, and the bottling workshop, finishing in the cellar where bottles age. Visitors see equipment that is still used in daily production, not static displays. The visit concludes with a tasting of the brewery's beers.

Where is it located?

The museum sits at Gheudestraat 56 in Anderlecht, a municipality of Brussels.

Frequently asked questions

Is this a working brewery or just a museum? It's a working brewery, Cantillon — the museum was created inside it to show the live production process rather than a reconstructed display.

When was the museum founded? In 1978, on the initiative of Jean-Pierre Van Roy, who wanted to preserve a unique method of spontaneous fermentation.

How is lambic different from ordinary beer? Lambic ferments spontaneously through wild yeasts naturally present in the air of the Zenne valley, with no cultivated yeast added, and it can only be brewed in winter.

Can visitors taste the beer after the tour? Yes, the visit includes a tasting of the beers produced by the brewery.
