The largest craft brewer in the U.S. is Samuel Adams maker Boston Beer (NYSE:SAM). Even though it has just 1% of the total market, it's leading a craft beer explosion. This segment saw a 15% year-over-year increase in sales while the megabrands -- led by Anheuser-Busch InBev (NYSE:BUD), SABMiller, and Molson Coors (NYSE:TAP) -- are experiencing flat growth and losing market share.
