Hops. This single plant, originally an ale preservative, has been used to create the flowery flavor of beer that adults have enjoyed for millennia. Now, researchers at UCal Berkeley have used CRISPR/Cas9 technology to modify several strains of Saccharomyces Cerevisiae (Brewer’s Yeast) to produce a hoppy flavor without using the signature plant. In a blind taste test facilitated by the Lagunitas Brewing Company, testers detected notes of “fruit loops” and “orange blossom” in the GMO-made beer.
