In the Americas With David Yetman

The explosion of craft beer brewing across the United States has created a widespread interest in the process of beer making. A beer festival in Tucson, Arizona, leads to some local brewers and sends David on a quest to the origin of what makes beer different - hops. Nearly all of the hops in the U.S. are cultivated around Yakima, Washington where the team follows the annual harvest and sample as many products of hop production as possible.
