A stroll through any Belgian city is a feast for the eyes with the country's impressive architecture and intricate stonework. But there's another trinity worthy of a pilgrimage: beer, chocolate and cheese. The greatest of these is beer. With more than 180 breweries producing at least 900 different varieties of beer, Belgium is a beer snob's version of heaven on Earth. Learning the finer points of Belgian beer can be daunting. Lambic beers are more like wine in taste. Fruit lambics come with the taste of cherries or raspberries and are often served in flute-style glasses. Gueuze beer can range from a sparkling crispness to a vinegary sourness. The white or wheat beers are often fermented with orange peels or other spices. The Trappist beers are distinctive for their history, taste and two-stage brewing.
