Helping to quench a growing thirst for American craft beer overseas, some of the United States’ largest craft breweries are setting up shop in Europe, challenging the very beers that inspired them on their home turfs.

It’s the latest phenomenon in the flourishing craft beer industry, which got its start emulating the European brews that defined many of the beer styles we drink today. The move also marks a continuing departure from the status quo of mass market lagers or stouts, demonstrating a willingness of American breweries to explore—and innovate—old world beer styles from Belgium, Germany and the United Kingdom.
