Founded in 1900 by Paul Cantillon, Brasserie Cantillon is a legendary family-run brewery located in the heart of Anderlecht, Brussels, Belgium. Over a century after its founding, the brewery remains in family hands and stands as one of the most iconic living monuments to traditional Belgian brewing. The brewery's address — Rue Gheudestraat 56, 1070 Brussels — has become a pilgrimage destination for beer lovers from around the world, drawn by Cantillon's unwavering dedication to ancient craft and its role as a guardian of Brussels' brewing heritage. Cantillon specialises exclusively in spontaneous fermentation, the cornerstone of true lambic brewing. Rather than using cultivated yeast strains, the brewery relies on wild airborne microorganisms native to the Senne valley to ferment its worts — a process that sets it apart from virtually every other brewery on the planet. From this tradition, Cantillon produces a range of lambic-based styles, including gueuze, kriek, and fruit lambics, all aged in wooden barrels, some of which are over a hundred years old. Cantillon is widely celebrated within the global beer community, earning exceptional ratings on platforms such as BeerAdvocate, and is regularly cited as a benchmark for lambic and gueuze. The brewery also hosts intimate events such as the Zwanze Day celebration, and has welcomed collaborations with respected breweries including Allagash Brewing. Visitors can explore the working brewery, witnessing active fermentation and the history of the craft firsthand.
