Brio Yeast Brio (Saccharomyces cerevisiae), A specialty yeast for complex, fruit driven red wines. Selected for its intense aroma purity and ability to enhance Pinot Noir varietal characteristics, Brio elevates a wine’s aromatic expressiveness with impressive notes of cherry, black fruits, and spice. Brio improves the extraction of phenolic compounds and color, which helps produce a complex, rounded wine. Renaissance Yeast’s strains have excellent fermentation kinetics, desirable sensory characteristics, and are produced to the highest quality standards. Renaissance Yeast is the exclusive developer of a novel, patented H2S-preventing technology that is the result of a natural trait in yeast that increases sulfur and nitrogen utilization efficiency during fermentation, thereby preventing hydrogen sulfide formation.
