Maredsous Abbey is a Benedictine monastery at Denée near Namur in Belgium. It is a member of the Annunciation Congregation of the Benedictine Confederation and was founded in 1872 from Beuron Abbey in Germany.
The abbey currently makes five varieties of cheese, and since 1963 has licensed its name to Duvel Moortgat Brewery (Brouwerij Duvel Moortgat), who brew three varieties of beer under the Maredsous name, all matured for at least three months before delivery. Although they are brewed outside the abbey, they are made with respect for the Benedictine tradition, and a substantial portion of the profits are donated to charitable causes.
