First Gene For Beer Foam Could Improve Froth
date:Nov 01, 2012
amy head consists of bubbles containing carbon dioxide gas, which yeast produces during fermentation. Proteins gather around the gas, forming the bubbles in the foam. Studies have shown that proteins from the yeast stabilize the foam, preventing the head from disappearing too soon. But until now, no one knew which yeast gene was responsible for making the foam-stabilizing protein.

The researchers identified the gene, which they call CFG1. The gene is similar to those already identified in wine
