A Trappist beer is a beer brewe by or under control of Trappist monks. Of the world's 171 Trappist monasteries (as of April 2005), seven produce beer (six in Belgium and one in The Netherlands). Only these seven breweries are authorized to label their beers with the Authentic Trappist Product logo that indicates a compliance to various rules edicted by the International Trappist Association (see details below).
