Located in Pipaix-Leuze, Belgium, Brasserie a Vapeur ("Steam Brewery") began as a farmstead brewery operated by successive generations of the Cuvelier-Biset family from 1785.
By the late 19th century, when the steam engine was installed, it was operating as a commercial brewery. Surviving both World Wars, in 1985 the brewery was sold by Gaston Biset to Jean Louis Dits, a history teacher, and his wife Anne-Marie "Sittelle" Lemaire. Their plan was to preserve the historic steam-powered brewery, and keep its oldest beer, the Saison de Pipaix, in production.
Today, the last Saturday of each month is brew day, when Brasserie a Vapeur opens to the public; Jean Louis demonstrates his process, and a large banquet is served in the adjacent farmhouse courtyard.
