Specific Inactivated Yeasts
Selected by Inter-Rhône - France
Saccharomyces cerevisiae cerevisiae
General Sensory Contribution
Enhances varietal aromas, palate volume and esters
Best suited for fermenting fruit forward, white and rose wines made from varieties such as Chenin Blanc, Semillon, Chardonnay, Viognier and Pinot Gris. Contributes to volume.Rhône 4600 was selected from Viognier by the Inter-Rhône’s technical department after a three-year study of yeast best suited for fermenting fruit forward, white wines made from varieties such as Chenin Blanc, Semillon, Chardonnay, Viognier and Pinot Gris, and also rosé wines made from varieties such as Cabernet Franc and Merlot. Wines that are fermented with the Rhône 4600 typically have enhanced apricot and tropical fruit due to strong fatty acid ethyl ester production, as well as high polysaccharide levels which confer excellent mouthfeel. Although the Rhône 4600 does not enhance the varietal character of Sauvignon Blanc or Semillon, this yeast does bring fullness and balance along with light aromatic ester notes as an excellent blending component.
