You've likely heard of some of the seasonal choices including Oktoberfest, Summer Ale, Winter Lager and Pumpkin Ale.

Granted this is impressive for a craft brewer, but it pales in comparison to the giants Anheuser-Busch Inbev ( BUD) and Molson Coors ( TAP), perhaps indicating an opportunity for future growth. At the forefront of this endeavor is the explosion of the craft brewing market. For instance, this market grew by about 15% over the last two years, compared with just 1% growth for the overall U.S. beer market. In 1980 there were just 89 breweries in contrast to the more than 2,500 today.
