London : The love for beer is trapped inside the yeast that creates its captivating taste, a new study suggests. Beer yeasts produce chemicals that mimic the aroma of fruits in order to attract flies that can transport the yeast cells to new niches, Belgian researchers have found. Interestingly, these volatile compounds are also essential for the flavour of beverages such as beer and wine. “The importance of yeast in beer brewing has long been underestimated. But recent research shows that the choice of a particular yeast strain or variety explains differences in taste between different beers and wines,” said Kevin Verstrepen from the University of Leuven. Yeast is essential in production of bread, beer and wine. Humans have been using yeast for thousands of years to produce bread, beer and wine. The microbes eat sugars and convert them into carbon dioxide gas and alcohol.
