The Brasserie d'Orval is a Belgian trappist brewery located within the walls of the Abbaye Notre-Dame d'Orval in the Gaume region of Belgium.
They produce just two beers, Orval and Petite Orval (the latter only available from the monastery itself). Distinctive in it's skittle-shaped bottle, Orval was first created in 1931 and has grown to iconic status and described by the beer critic Michael Jackson to be "a world classic".
