Westmalle Brewery

Westmalle Brewery is the brewing operation of the Trappist Abbey of Westmalle in Belgium. Its formal historical name is Brouwerij der Trappisten van Westmalle. The brewery is owned and overseen by the abbey, while most day-to-day production work is carried out by secular employees rather than monks. Its beers carry the Trappist designation associated with the International Trappist Association, reflecting the brewery’s location within the abbey, its connection to the monastic community, and the use of brewing income to support the abbey and its charitable responsibilities. The brewery’s origins date to 1836, when Martinus Dom, the first abbot of the Trappist community at Westmalle, decided that the monastery should produce its own beer. The first brew was made on 1 August 1836 and consumed by the community later that year. Early beer was relatively light and sweet, but the range developed over time. A stronger brown beer introduced in 1856 is regarded as the historical ancestor of the dubbel style. Commercial sales began locally in the nineteenth century and expanded more substantially after the brewery entered broader trade distribution in the twentieth century. Westmalle is especially associated with the development and international recognition of Belgian abbey-style beer. In 1934 the brewery produced a strong, pale, golden beer and gave it the name Tripel. The term subsequently became widely used for a category of strong Belgian pale ales, although many later beers using the designation are not connected with Westmalle. The modern Westmalle Tripel is a 9.5% alcohol-by-volume beer brewed from pale pilsner malt, candy sugar, and a combination of European hop varieties. It undergoes extended secondary fermentation and bottle conditioning with additional sugar and yeast. The recipe is described as having remained unchanged since 1956. The regular portfolio consists of three beers. Westmalle Dubbel is a dark, 7% beer traditionally identified by its purple label. Westmalle Tripel is the brewery’s best-known flagship, a pale 9.5% beer with a yellow label. Westmalle Extra is a lighter 5% patersbier, historically intended primarily for consumption by the monks during their working day and distributed more selectively than the two stronger beers. The brewery has also made occasional limited releases, including a 2025 blend called Westmalle Duo, combining Tripel and Extra. The operation has been enlarged and modernized repeatedly while retaining its monastic ownership and traditional product identity. A major new brewery was built in 1933, and the facilities were remodeled in 1991. The brewery’s identity is based less on mass-market branding than on provenance, continuity, bottle-conditioned production, and adherence to Trappist standards. In addition to brewing, Westmalle Abbey is associated with agricultural activities including milk and cheese production. Westmalle beers are sold in Belgium and exported to international markets, where they occupy a premium position in the Belgian specialty-beer and Trappist-beer segments.

Westmalle’s brewing history is inseparable from the history of the Trappist abbey in the Belgian village of Westmalle. The abbey was founded on 6 June 1794 and was formally elevated to Trappist abbey status on 22 April 1836. In that same year, Abbot Martinus Dom determined that the community should brew its own beer. The first recorded brew took place on 1 August 1836, and the monks drank the beer for the first time on 10 December. Father Bonaventura Hermans and Albericus Kemps were among the early brewers. The initial beer was described as mild in strength and comparatively sweet, reflecting its role as a monastic beverage rather than a commercial specialty product. The range expanded in 1856 with the introduction of a stronger brown beer. This beer is commonly treated as the ancestor of the dubbel style, although the contemporary Westmalle Dubbel derives more directly from a recipe developed in 1926. Local sales began in 1856, and the oldest recorded sale is dated 1 January 1861. As demand increased, the brewery was enlarged and rebuilt in 1865, drawing inspiration from the Trappist brewery at Forges, near Chimay. Father Ignatius van Ham joined the brewing team during this period. Westmalle’s transition toward organized commercial distribution accelerated in the twentieth century. Sales to traders began in 1921, and a completely new brewery was constructed in 1933. In 1934 the brewery produced a strong, pale ale of 9.5% alcohol by volume and named it Tripel. The name later became a standard description for a class of strong Belgian pale ales, making Westmalle an important reference point in the development of modern Belgian beer terminology. The brewery’s current Tripel is associated with this historical innovation, even though the wider style is now produced by many breweries. The modern Westmalle Tripel recipe is described as unchanged since 1956. It uses pale pilsner malts, pale candy sugar, Styrian Goldings and other German hops, and Saaz-type pilsner hops. After primary fermentation, the beer receives a long secondary fermentation and is conditioned in the bottle with additional sugar and yeast. This process contributes to the beer’s continued fermentation and distinctive strength. Westmalle Dubbel is a darker 7% beer, while Westmalle Extra is a lighter 5% patersbier traditionally associated with the monks’ daily consumption. The brewery was remodeled in 1991 and developed industrial-scale packaging capacity while remaining under abbey ownership. Historical reference material reports a bottling capacity of approximately 45,000 bottles per hour and annual output of about 120,000 hectolitres in 2004. These figures are historical and do not establish current production. The workforce has increasingly consisted of outside secular employees; reference material describes a community of 22 monks and approximately 40 external staff, although staffing levels may have changed. Westmalle continues to produce its three regular beers and has occasionally released additional beers in limited quantities. In March 2025 it introduced Duo, a blend of Tripel and Extra at 7.2% alcohol by volume, produced in a limited edition of approximately 5,000 barrels and made available through selected cafés. The abbey also produces milk and cheese. Across its activities, Westmalle combines monastic governance, agricultural self-sufficiency, and commercial brewing. Its brand reputation rests on the Trappist designation, historical continuity, and the perceived authenticity of beer produced within an operating monastery rather than on broad advertising or rapid product proliferation.

• Westmalle DubbelTrappist dubbel beer1926

  Westmalle Dubbel is a dark Belgian Trappist beer with an alcohol content of approximately 7% by volume. It is traditionally associated with a purple label and descends from the brewery’s historical brown-beer tradition. The modern product is linked to a recipe first brewed in 1926. It is one of Westmalle’s two principal export beers and represents the brewery’s darker, richer counterpart to the pale Tripel.

• Westmalle TripelTrappist tripel beer1934

  Westmalle Tripel is a pale golden beer at 9.5% alcohol by volume and the brewery’s most internationally recognizable offering. First brewed in 1934, it is made with light pilsner malts, pale candy sugar, and several European hop varieties. The beer undergoes extended secondary fermentation and is bottle-conditioned with additional sugar and yeast. Its yellow label and strong but pale profile have made it a benchmark for the broader Belgian tripel category.

• Westmalle ExtraPatersbier

  Westmalle Extra is a lighter 5% beer traditionally brewed for consumption by the monks during the working day. It carries a blue label and is generally less widely available than Dubbel and Tripel. The beer provides a lower-strength expression of the brewery’s fermentation and ingredient profile while remaining connected to the abbey’s daily monastic life.

• Westmalle DuoLimited blended Trappist beer2025

  Westmalle Duo is a limited-release blend combining approximately 60% Westmalle Tripel with 40% Westmalle Extra. At 7.2% alcohol by volume, it sits between the strengths of its component beers. The 2025 release was produced in a limited quantity and distributed through a small number of selected cafés rather than offered as a broadly available regular product.
