[1] The Trappist abbey in Westmalle (officially called Abdij Onze-Lieve-Vrouw van het Heilig Hart van Jezus) was founded 6 June 1794, but the community was not elevated to the rank of Trappist abbey until 22 April 1836.The brewery was enlarged and rebuilt in 1865 based on the example set by the Trappists of Forges (nearby Chimay).The majority of the workers in the brewery are no longer monks, but secular staff brought in from outside.Westmalle Extra has a blue label and is a 5% abv beer with limited availability, i.e. a patersbier.[4][5] It has been speculated that Westmalle's choice of three types of beers was based on the Holy Trinity.
