Shopping for hops: Brewers' annual journey to find the best hops
The craft beer movement in the U.S. has been powered by hops, the flower that gives beer a wide range of flavor.

Most of that crop comes from the Yakima Valley in Washington state, where top brewers head every September to personally shop for their hops. Dana Jacobson reports.
