The beer industry consolidation that's taken place over the last decade isn't happening by accident. AB-InBev (NYSE: BUD) and Molson Coors (NYSE: TAP) essentially control the beer market in the U.S. and are major powers globally, which has left smaller brewers searching for options. They can try to fight the big beer powers (which may be a losing battle), or join forces, something Craft Brew Alliance (NASDAQ: BREW) did in a production and distribution deal with AB-InBev.
