Brouwerij Westvleteren is one of the most renowned and highly regarded Trappist breweries in the world, located within the walls of the Sint-Sixtus Abbey in the village of Westvleteren, in the Belgian region of West Flanders. The brewery was founded by Cistercian monks in 1838 and has remained true to a tradition of modest, limited, and uncommercialized production.

Unlike commercial breweries, this Trappist community brews beer solely to support monastic life and charitable activities, in accordance with the principles of the International Trappist Association. The brewery is especially famous for its beers Westvleteren 12 and Westvleteren 8, both frequently ranked among the best beers in the world.

What further sets this brewery apart is its unique distribution system: the beer can only be purchased through advance reservation and directly from the abbey, with no commercial labels – the bottles are marked only by a cap indicating the beer type. Its limited availability, strict purchasing rules, and unwavering commitment to quality have contributed to the near-legendary status of this small monastic brewery.
