We'll drink to this: 1,927 U.S. breweries were operating at some point in 2011 as of November, according to the Brewers Assn. That's the most since the late 1800s. The reason? The popularity of craft beers, whose sales rose to $7.6 billion in 2010, up from $7 billion the previous year. The two largest craft brewers are Boston Beer Co., which makes Samuel Adams, and the Sierra Nevada Brewing Co. Many smaller brewers include Blatant Brewery, Clown Shoes Beers, and Tin Whiskers Brewing -- names that likely make more sense once you've sampled their wares.
