Scientists Have Identified A Yeast Gene That Gives Wine And Beer Special Flavors

November 14, 2017

This particular study was led by Johan Thevelein working with Maria R. Foulquié-Moreno, each at the Center For Microbiology at VIB a Flanders-based life science institute. They applied high-throughput genomic analysis to study a hybrid strain of Saccharomyces cerevisiae, the yeast that ferments wine (and beer). The researchers found "swaths of DNA" containing multiple genes with one causative gene linked to high production of the flavor compound phenylethyl acetate. They also identified the part of genes that are responsible for intense production of the flavor.
