Renaissance Yeast Inc. is a leader in the development and commercialization of hydrogen sulfide-preventing wine yeasts for winemakers worldwide. Our highly experienced research staff is dedicated to developing yeasts that address and solve some of the industry’s most important challenges. The hydrogen sulfide-preventing traits of our proprietary and patent-pending wine yeasts were discovered by Dr. Linda Bisson and her research team in the Department of Viticulture and Enology at the University of California, Davis, through research funded by the American Vineyard Foundation. Renaissance Yeast is the exclusive global licensee from the University of California for this innovative advancement in wine. Through the application of classical breeding techniques, Renaissance Yeast has further developed this yeast technology into commercially successful hydrogen sulfide-preventing wine yeasts. These are now available to help winemakers produce more cost-effective, appealing vintages unblemished by hydrogen sulfide's negative effects. In essence, the use of Renaissance Yeasts unmasks the wine’s true character and complexity that may be otherwise obscured by the hydrogen sulfide that is produced in some amount in traditional wine yeast fermentation.

Renaissance Yeast OSSIA is a robust and versatile organic yeast for making complex, aromatic organic wines. Ossia is Renaissance’s high performance certified organic (NOP/COR) yeast that prevents the formation of H2S. In organic winemaking, H2S and its associated reductive character faults can’t be minimized by the conventional methods of adding inorganic nitrogen or copper. Ossia is an exciting new tool for organic winemakers to proactively guard against reductive faults while also improving aroma profiles through increased expression of tropical fruit esters.
