Grimbergen is a group of Belgianabbey beers. The name refers to the abbey that Saint Norbert of Xanten built for the Premonstratensian (Norbertine) canons regular in Grimbergen in 1128 and where the beer was first brewed. They became famous for providing hospitality and their home-brewed beer to visitors, and allegedly handed down the recipe over the centuries. The beers are now brewed by two companies : Alken Maes brewery group in Belgium and Kronenbourg Brewery in France, which have developped different varieties. The Belgian varieties are: Blond, Dubbel (brown), Tripel (blond), Optimo Bruno (brown), and the latest innovation Grimbergen Gold (blond). A 'limited edition' Christmas Beer (Brassin de Noël) is sometimes produced for the year-end festivities.
