Engineered Yeast Makes Hoppy Flavors

Can you brew a hoppy beer without hops? Beer purists might regard the idea with suspicion, but researchers at UC Berkeley, with some help from UC Davis’ “Pope of Foam,” have shown that you can brew a tasty hoppy beer using gene-edited yeast to replace hop flavors.

According to Charles Denby, a former postdoctoral researcher at UC Berkeley, growing hops uses a lot of water – 50 pints of water to grow enough hops (the crumbly flowers of the hop vine) for a pint of craft beer.
