Bioengineering Beer Foam

Reporting in the Journal of Agricultural and Food Chemistry, Tomás González-Villa and colleagues devised a recipe for improving beer foam. They identified a gene in brewer’s yeast that prolongs beer foam lifespan by making a protein that protects the bubbles. They say they’ve brewed beers with heads that stay frothy for several hours.
