A Definition List: Belgian Beer Types

Amber ales: These are beers similar to the traditional pale ales of England, although somewhat less bitterly hopped. A notable example is the 5% abv De Koninck brand, with its distinctive spherical glasses (called 'bollekes').
Blonde or golden ale: These are a light variation on pale ale, often made with pilsener malt. Some beer writers regard blonde and golden ales as distinct styles, while others do not.
Brown Ale: Regular bruin or brune beers such as Grottenbier are darker than amber ales, less sour than Flemish brown ale, and less strong than dubbel.
Dubbel: Dubbel has a characteristic brown color. It is one of the classic Abbey/Trappist types, having been developed in the 19th century at the Trappist monastery in Westmalle.
Enkel: This beer is the basic recipe for what was traditionally a range of three beers of increasing alcohol content.
Flemish Red: Typified by Rodenbach, the eponymous brand that started this type over a century ago, this beer's distinguishing features from a technical viewpoint are a specially roasted malt, fermentation by a mixture of several 'ordinary' top-fermenting yeasts and a lactobacillus culture and maturation in oak.
