There are only 10 Trappist breweries in the world: six in Belgium, 1 in the USA, 1 in Austria, and 2 in the Netherlands-including the Brewery de Koningshoeven and home of La Trappe. The friars handed over production to commercial brewers in the middle of the last century but retook control and began making Trappist style beers in 1980. It goes without saying that only natural ingredients are used in the production according to a recipe developed by the monks which utilises water from its own source.
The La Trappe family of beers is brewed at the De Koningshoeven Brewery—the only certified Dutch Trappist brewery. Brewing within the walls of the Onze Lieve Vrouw van Koningshoeven Abbey since 1884, the La Trappe Dubbel Trappist ale is a classic dark Trappist ale with a full flavour.
