Brasserie de Saint-Sylvestre is an independent family brewery based in Saint-Sylvestre-Cappel, a small town in the Nord-Pas-de-Calais region of northeast France. The brewery has been family-owned since 1920, rooted in the agricultural and brewing traditions of French Flanders. It stands as one of the most prominent breweries in the region, maintaining an independent character across generations. The brewery is best known for its Bière de Garde, a traditional French farmhouse ale style that has long defined the brewing culture of northern France. Its portfolio reflects the terroir and heritage of the Flemish border region, with a focus on malt-forward, bottle-conditioned ales that ferment at cellar temperature. Saint-Sylvestre has built a reputation for both domestic and export markets, with strong demand across Europe and North America. The brewery's signature beer, 3 Monts, is a Flanders Golden Ale that has become iconic among Bière de Garde enthusiasts worldwide. Named after the three hills of French Flanders, it represents the brewery's identity and regional pride. Saint-Sylvestre is widely regarded as a key reference for the Bière de Garde style on the international craft beer scene.
