A dubbel (also double) is a Belgian Trappist beer naming convention. The origin of the dubbel was a beer brewed in the Trappist Abbey of Westmalle in 1856. Since 1836, the abbey had brewed a light-colored beer that was quite sweet and light in alcohol for consumption by the monks. The new beer, however, was a strong version of a brown beer. In 1926, the recipe was changed, and the first dubbel was released by Westmalle Abbey as Dubbel Bruin. The first written record of its sale by the abbey was on June 1, 1861. Following World War Two, abbey beers became popular in Belgium, and the name "dubbel" was used by several breweries for commercial purposes.
