Westmalle belongs to just a handful of present day Belgian Trappist breweries. Originating in the Westmalle Abbey and first brewed by abbot Martinus Dom in 1836, Westmalle are largely credited with brewing the first strong golden ale to use the term Tripel. Just three beers are produced at Westmalle: Dubbel at 7%abv and Tripel at 9.5%. Their third ale, Extra is a medium strength beer with very limited availability said to be drunk by the monks during the working day. It has been suggested that the breweries lineup of just three beers is a direct reference to the Holy Trinity.
