Understanding brewing trait inheritance in <i>de novo</i> Lager yeast hybrids.

ABSTRACT: Hybridization between Saccharomyces cerevisiae and Saccharomyces eubayanus resulted in the emergence of S. pastorianus, a crucial yeast for lager fermentation. However, our understanding of hybridization success and hybrid vigor between these two species remains limited due to the scarcity of S. eubayanus parental strains. Here, we explore hybridization success and the impact of hybridization on fermentation performance and volatile compound profiles in newly formed lager hybrids. By selecting parental candidates spanning a diverse array of lineages from both species, we reveal that the Beer and PB-2 lineages exhibit high rates of hybridization success in S. cerevisiae and S. eubayanus, respectively. Polyploid hybrids were generated through a spont
