Craft beer is an exploding phenomenon, both in the U.S. and worldwide, with local, independently-owned breweries popping up all over the country. We hear from Charlottesville, VA's Champion Brewery boys Hunter Smith and Levi Duncan, as they explain why they chose to brew beer, and offer their view on the craft beer craze. Then, Matt Nissen and Elliott Thompson, of the Alluvial Brewing Company in Ames, IA, detail their beer brewing process and explain what exactly a hop is and how it's used. Produced by Sprouts.
