Brouwerij der Trappisten van Westmalle is a renowned Trappist brewery located within the Abbey of Our Lady of the Sacred Heart, in the village of Westmalle, in the Belgian province of Antwerp. This brewery is part of an authentic Trappist community, meaning that the beer is brewed by monks or under their supervision, within the monastery walls, and the proceeds are used to support the community and charitable causes. The brewery was founded in 1836, when the monks first began brewing beer for their own needs.
