Crispr-augmented brewer’s yeast produces flavour molecules, enabling hoppy beer without adding extra hops
US scientists have genetically engineered brewer’s yeast to make beer that has hoppier flavours without actually adding hops to give that effect. Charles Denby and Rachel Li from University of California, Berkeley, and colleagues inserted genes for enzymes so that yeast produces flavour molecules linalool and geraniol, as well as ethanol.
