Great news for lager lovers! Researchers are opening up new horizons of taste for lager beers, which typically don’t vary much in flavor.
This relative uniformity of flavor among lagers is significantly due to a lack of genetic diversity among yeasts.
Genetic studies have shown that lager yeasts resulted from just two crosses between the parent yeasts, Saccharomyces cerevisiae, and S. eubayanus. The problem is that the two yeast species are so different that it makes successful crosses rare.
