Trappist brewing is the most closely regulated designation in the beer world, the term “Authentic Trappist Product” requires that the beer be brewed within the walls of a Trappist monastery, under the supervision of monks, with profits going primarily to the monastery’s needs and charitable causes. I’ve visited two Trappist breweries in Belgium and corresponded with homebrewing monks, and the reality of Trappist brewing is both more mundane and more fascinating than the mystique suggests.
Trappist breweries and monks: history and the ATP designation
The Cistercian and Trappist monastic tradition: The Cistercian Order of the Strict Observance (Trappists, named after the La Trappe monastery in Normandy where the reformed rules originated in 1664) emerged from a reform movement within the Benedictine monastic tradition. Benedictine monasteries had brewed beer for centuries as both a source of sustenance (beer being safer than untreated water in medieval Europe) and as a product for sale to support the monastery. Trappist monks maintained the tradition of self-sufficiency through craft production, including brewing, cheese-making, and bread. The six founding Belgian Trappist breweries: Belgium is the heartland of Trappist brewing. The founding monasteries: Westvleteren (founded 1839), Rochefort (1595 but modern brewing from 1899), Chimay (1850), Achel (now dissolved brewing operations), Orval (1931), and Westmalle (1836). Each developed distinctive house styles: Westvleteren Abt 12 is frequently cited as one of the world’s greatest beers but is only available at the monastery or in limited allocations. Orval’s unique character comes from Brettanomyces wild yeast aged in the bottle. Chimay expanded into commercial production and is the most widely available Trappist beer globally. The ATP designation: The International Trappist Association established the “Authentic Trappist Product” hexagonal logo in 1997 to prevent non-monastic breweries from marketing their beers with the Trappist association. To use the ATP logo, a beer must: be brewed within the walls of a Trappist monastery, be produced under the monks’ supervision, generate profit for the monastery (not for commercial shareholders), and contribute to social works through any surplus profits. Currently 14 breweries worldwide hold the ATP designation, including breweries in the Netherlands, Austria, Italy, England, and the United States in addition to Belgium. What makes Trappist beer distinctive: Most Trappist ales are high-gravity Belgian ales (6–12% ABV) fermented with distinctive Belgian yeast strains that produce fruity esters and phenolic spicy notes. The yeast strains are specific to each monastery and create the house character that distinguishes, for example, Chimay’s plum-spice notes from Orval’s barnyard-Brett character.
Common Questions
What is the difference between Trappist beer and Abbey beer?
Trappist beer and Abbey beer are frequently confused because both terms reference Catholic monastic traditions, but the distinction is legally and commercially significant. Authentic Trappist Product (ATP): brewed within a Trappist monastery under the ATP criteria described above. The hexagonal ATP logo on the label is the guarantee. Currently 14 breweries worldwide. Abbey beer (Bières d’Abbaye in French): a marketing category, not a regulated designation. An Abbey beer is any beer brewed with some connection, licensing agreement, charitable donation, or historical association, with a monastery or religious institution. The monastery typically licenses its name and image to a commercial brewer in exchange for a royalty. The beer may or may not be brewed according to any monastic recipe or tradition. Leffe (owned by AB InBev and brewed at a large commercial facility) is labeled as an Abbey beer because it licenses the name of the Leffe Abbey, which was destroyed during the French Revolution and has no current brewing operation. Grimbergen, Affligem, and dozens of other Belgian “Abbey beers” follow the same commercial licensing model. The practical implication: when buying Trappist beer, look for the ATP hexagonal logo, this is the only reliable guarantee of monastic origin. The word “abbey” or a monastery name or illustration on a label does not guarantee any connection to actual monastic brewing. For homebrewers interested in replicating these styles: the Belgian yeast strains available commercially (Wyeast 3787 for Westmalle-character, WLP540 for Chimay-adjacent character, WLP510 for Orval-type Brett) are derived from commercial sources and produce very similar character to the monastery originals, Trappist-inspired homebrewing is one of the most rewarding Belgian brewing projects.
