A new microbiological medium for the detection of Saccharomyces cerevisiae var. diastaticus has been invented at Saint Joseph’s University. Saccharomyces cerevisiae var. diastaticus is a wild yeast contaminant which represents a major beer spoilage threat. Product contamination has led to costly product recalls as infection may lead to off-flavors, over-attenuation, and over-carbonation, thus causing gushing […]
Food Technology & Plant Science
LICENSED: 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.
