Beer in Belgium varies from pale lager to amber ales, lambic beers, Flemish red ales, sour brown ales, strong ales and stouts. In 2018, there were approximately 304 active breweries in Belgium, including international companies, such as AB InBev, and traditional breweries including Trappist monasteries. On average, Belgians drink 68 liters of beer each year, down from around 200 each year in 1900. Most beers are bought or served in bottles, rather than cans, and almost every beer has its own branded, sometimes uniquely shaped, glass. In 2016, UNESCO inscribed Belgian beer culture on their list of the intangible cultural heritage of humanity.
