In pool, success starts with a solid break. In brewing, it’s all about a solid process. That’s why I brew Kräftig according to Reinheitsgebot, the German Beer Purity Law. And like a solid break … … the results speak for themselves. That’s strong, Billy. That’s Kräftig. Enjoy the stronger flavor of Kräftig lager and light. Purity Brewed American Beer.
