Quick Facts

Brewing a Dream: From Family Roots to Industry Trailblazer

Koch’s story begins in Cincinnati, where he was born into a family with deep brewing roots. His father came from a line of German-American brewers — making Koch a descendant of a nearly generational brewing legacy. 

After earning his credentials — a B.A., J.D., and MBA from Harvard University — Koch briefly worked as a consultant at Boston Consulting Group and as an instructor for Outward Bound.  Yet something tugged at him: the family brewing recipe, passed down through generations. In 1984, he left consulting, rummaged through his family attic and resurrected a great-great-grandfather’s lager recipe — a bold personal gamble. 

From his kitchen came the first batch that would become Samuel Adams Boston Lager. With minimal outside support — mostly funds raised from family and friends — Koch set out to build something different. His early days were marked by door-to-door pitches to bar owners and an unshakeable belief in “craft over corporate.”
