James Watt and Martin Dickie founded BrewDog in 2007 and have grown it to become one of Scotland's largest independently owned breweries. Since starting the company, the two have become evangelists for the craft beer movement, trying to convert people into fans one beer at a time. In this series, the Scots head across the Atlantic to share their enthusiasm for craft brews in major U.S. cities. At each stop on their journey, Watt and Dickie celebrate the city's distinctive beers and create their own locally inspired -- and often outrageous -- drafts, including brewing the world's most caffeinated beer in Seattle and a clam-infused beer in Boston. It's all part of the guys' goal to get people thinking about beer in a new way.
