Claus-Peter Lumpp has held three Michelin stars since 2007. At his restaurant Bareiss in the town of Baiersbronn, tucked away in Germany's Black Forest, he's been cooking up a storm for almost 20 years. He was born in the southwest German town of Tübingen in 1964 and learned the art of cooking from his grandmother. Lumpp later refined his skills at some of Europe's top restaurants.
