The article discusses the history and mystery surrounding lager yeast, focusing on its origins and development. Lager yeast, known for its role in producing pale, bubbly, and refreshing beers, has long puzzled scientists and historians due to the unknown source of its creation. Recent research has shed light on a new theory suggesting that lager yeast emerged from a hybridization event between ale yeast (Saccharomyces cerevisiae) and a cold-tolerant wild yeast (Saccharomyces eubayanus) in a Bavarian brewery in the early 1600s. This rare mating resulted in a distinct new species, lager yeast, which revolutionized the beer industry. The study of lager yeast's genetic lineage led researchers to pinpoint its origins to a specific time and place, providing insights into its development. The article delves into the historical context of Bavarian brewing practices, including the influence of the Reinheitsgebot (Beer Purity Law) and the role of the Wittelsbach royal family in shaping beer production. Through a combination of genetic analysis and beer history, researchers have made significant strides in unraveling the mystery behind the world's beloved lager yeast.
