St. Bernardus is an Abbey brewer, although their history is entwined with that of the Trappist monks. The story goes that in the 1800s, anticlericalism forced the Catsberg Abbey community to leave France for Belgium, where they founded the Refuge Notre Dame de St. Bernard. Around 100 years later they entered into an agreement with neighbouring abbey St. Sixtus to brew and market their Trappist beer. When this agreement came to an end in 90’s, St. Bernardus began brewing the same styles under their own name, although they could no longer call it Trappist beer. As you might expect, the numbers given to each brew are some indication of their alcohol content - the higher the number, the stronger the beer.
