Go anywhere in the world and beer drinkers have probably heard of Bud, Coors, and Heineken. But, according to the experts at The Drink Business, another brand topped them all in 2011. Though there are a huge number of big-name beers out there, there are only a handful of big breweries. AB InBev owns Budweiser, Corona, and Labatt as well as Michelob, Stella Artois, Becks, Bass, St. Pauli Girl, and 59 other brands. The Molson Coors Brewing Company owns Keystone, Blue Moon, and a host of others, in addition to Molson and Coors. SABMiller owns Miller, Milwaukee's Best, Grolsch, and 58 percent of the Molson Coors Brewing Company (it also operates as MillerCoors). Some say that these guys are so huge that they spill more beer than Samuel Adams brews. The Drink Business points out that their analysis is based on volume sales, not taste. So, craft-brew and home-brew aficionados, avert your eyes.
