In this episode, we uncover the fascinating history of lager yeast, the unsung hero behind the world’s favorite crisp and clean lagers. Based on research from FEMS Yeast Research, we explore the origins of Saccharomyces pastorianus and how this hybrid yeast emerged from a unique confluence of brewing traditions, innovation, and chance.

Dive into the intriguing “Hofbräuhaus Hypothesis,” which suggests the legendary Munich brewery played a pivotal role in creating lager yeast by bringing together top-fermenting and bottom-fermenting strains. We’ll also discuss the contributions of Saccharomyces eubayanus, a mysterious cold-tolerant yeast discovered in Patagonia and Ireland, and how brewers in the 19th century perfected the art of pure yeast cultures.

Join us for a journey that spans continents, centuries, and scientific breakthroughs, shedding light on how one yeast changed the course of brewing history and continues to inspire innovation today. Raise your glass to the origins of lager yeast and the incredible stories it tells. Sláinte!
