Saccharomyces eubayanus, a type of yeast, is a likely parent of the lager brewing yeast, Saccharomyces pastorianus.[1][2]
Lager is a type of beer created from malted barley and fermented at low temperatures, originally in Bavaria. S. eubayanus was discovered in Patagonia, possibly being an example of Columbian exchange.[3][4]
The South American origins of S. eubayanus have been subsequently challenged by genomic and phylogenetic evidence suggesting a Tibetan origin. The authors of this study argue that their result also "corresponds better with geography and world trade history."[5]
