Washington : If you are a beer lover, you already know that lager beers differ little in taste than the tastier ale beers.
Now, researchers have developed new yeast strains that will soon result in sizzling new beer flavours, reports IANS.
Compared to lager yeasts, ale yeast ferments more quickly and often produces a sweeter, fuller-bodied and fruitier taste.
On the other hand, the uniformity of flavour among lager beers results from a lack of genetic diversity among the yeasts.
Genetic studies have shown that lager yeasts result from just two crosses between the parent yeasts — Saccharomyces cerevisiae and S eubayanus.
“We figured that if we could create more crosses between S. cerevisiae and S. eubayanus, we would perhaps produce a set of more diverse lager yeasts, which could yield more diverse lager beers,” explained Kevin Verstrepen, professor in genetics and genomics from University of Leuven in Belgium.
