Lalvin Rhône 4600® was selected from Viognier by the Inter-Rhône’s technical department after a three-year study of yeast well suited for fermenting fruit-forward, elegant white and rosé wines. High sugar and low nitrogen musts, when fermented cool (13.5°C) with the Rhône 4600®, have enhanced apricot and tropical fruit due to strong fatty acid ethyl ester production. Higher roundness with diminished bitterness also makes the Rhône 4600® a good choice for Rhône white varietals and Chardonnay. Although the Rhône 4600® does not enhance the varietal character of Sauvignon blanc or Semillon, this yeast does bring fatness and balance along with light aromatic ester notes as a good blending component.
