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.

Ossia (Saccharomyces cerevisiae hybrid), Renaissance Yeast’s latest H2S-preventing strain, provides a high-quality advance for organic winemakers. Making an all-natural organic wine can sometimes present its challenges. One of these is H2S and its associated reductive character faults that cannot be minimized by conventional means such as inorganic diammonium phosphate to the must or using inorganic copper sulphate to remediate a problematic wine.
