"One of the newest and most interesting styles of beer, the Bière de Champagne has much potential within the beer industry as a top-shelf crossover beer. Primarily brewed in Belgium, these beers typically undergo a lengthy maturation. Some are even cave-aged in the Champagne region of France and are then subjected to remuage and dégorgement, which is the "methode de champenoise" process of removing yeast from the bottle. Most are delicate, high in alcohol, highly carbonated and sometimes spiced. Color can range from very pale to dark hues."
