similar in style or presentation to monastic beers. In other words, an Abbey beer may be: produced by a non-Trappist monastery—e.g. Benedictine; or produced by a commercial brewery under commercial arrangement with an extant monastery; or branded with the name of a defunct abbey by a commercial brewer; In 1999, the Union of Belgian Brewers introduced a "" () logo to indicate beers brewed under license to an existing or abandoned abbey, as opposed to other abbey-branded beers which the trade markets using other implied religious connections, such as a local saint. The requirements for registration under the logo include the monastery having control over certain aspects of the commercial operation, and a proportion of profits going to the abbey or to its designated charities. Monastic orders other than the Trappists can be and are included in this arrangement. The "Abbey beer" logo and quality label is no longer used for beers given the name of a fictitious abbey, a vaguely monastic branding or a saint name without mentioning a specific monastery. Some brewers may produce abbey-style beers such as dubbel or tripel, using such names but will refrain from using the term Abbey beer in their branding. What connoisseurs now recognize as Trappist breweries began operations in 1838. Several monasteries, however, maintained "working" breweries for 500+ years before the French regime disrupted religious life (1795–1799). Even then, some Abbey beers such as Affligem Abbey, whose name now appears on beers made by the Heineken-owned Affligem Brewery, resumed brewing from "working" monasteries until the occupation of most of Belgium in World War I. Commercial Abbey beers first appeared during Belgium's World War I recovery. Although Abbey beers do not conform to rigid brewing styles, most tend to include the most recognizable and distinctive Trappist styles of brune (Belgian brown ale, aka dubbel), strong pale ale or tripel, and blonde ale or blond. Modern abbey breweries range from microbreweries to international giants, but at least one beer writer warns against assuming that closeness of connection with a real monastery confirms a product's quality. , 18 certified Abbey beers existed: Achel sells Achel 5 Blonde (5% ABV, draught only), Achel 5 Brune (5% ABV, draught only), Achel 8 Blonde (8% ABV, tripel), Achel 8 Brune (8% ABV, dubbel), Extra Blonde (9.5% ABV.tripel), Extra Brune (9.5% ABV, dubbel).
