GY7B: A New Yeast Species

Yeast stain GY7B is a novel, lactic-acid producing yeast capable of acidifying beer to pH3.5 in as little as five days with final attenuation at 2-3 weeks.

Typical sour beer production relies upon secondary fermentation with bacteria to develop a complex sour beer flavor profile which can take months or years to fully develop.
