The scientists said on Tuesday that the yeast, called Lalvin W15, could be used around the world during the fermentation process.

The yeast enhances a wine's quality by limiting the production of acetic acid, which improves flavour, they reported. It also increases glycerin, which helps keep a wine balanced and smooth.

Additionally, Lalvin W15 boosts a wine's succinic acid concentration, which lowers the pH and hinders the growth of unwanted, unhealthy bacteria.
