Cantillon: The Church of Wild Fermentation
A living, breathing museum where the airborne yeast of the Zenne valley dictates every drop.
The Vibe
Walking into Brasserie Cantillon in the gritty Anderlecht neighborhood is a visceral experience. Dust is treated as an essential ingredient here. The Van Roy family has kept this facility operating exactly as it did in 1900, completely insulated from the stainless-steel sterility of modern brewing. Up in the attic, the massive copper coolship sits under louvred wooden windows. On cold winter nights, they open those windows to let the wild Brettanomyces yeast floating in the Brussels air sweep over the cooling wort. It is chaotic, deeply traditional, and utterly fascinating.
What To Order
This is not the place for a sweet, easy-drinking pint. You are here for complexity. Start with a classic Gueuze—a masterful blend of one-, two-, and three-year-old lambics that undergoes a secondary fermentation in the bottle.
The flavor profile is notoriously polarizing: intensely tart, dry, acidic, with deeply funky notes often affectionately described by devotees as "horse blanket" or wet hay. If you prefer fruit, opt for the Kriek (macerated with sour cherries) or the Fou' Foune (made with Bergeron apricots). It drinks closer to a complex, skin-contact natural wine than a traditional beer.
