Brewing hoppy beer without the hops

Using generic engineering to make hoppy beer by modifying yeast with genes from basil and mint.

"The engineered yeast strains were altered using CRISPR-Cas9, a simple and inexpensive gene-editing tool invented at UC Berkeley. Denby and Li inserted four new genes plus the promoters that regulate the genes into industrial brewer's yeast. Two of the genes – linalool synthase and geraniol synthase – code for enzymes that produce flavor components common to many plants. In this instance, the genes came from mint and basil, respectively."
