Uvaferm SVG
(Saccharomyces cerevisiae cerevisiae)
For fresh fruity wine styles.
Product details
The Institut Technique du Vin (ITV), in collaboration with Lallemand, selected SVG from the Loire region specifically for the enhancement of typical Sauvignon Blanc varietal character. Also suited to other aromatic white varieties such as Pinot Gris and Riesling, and generally favoured for the production of fresh fruity white wine styles. In tastings of Sancerre and Pouilly Fume wines fermented with yeasts commonly used for Sauvignon Blanc, the wines fermented with SVG scored higher than those fermented with other yeasts, and were described as having more intensity and a more favoured balance of mineral, citrus and spicy notes. In Australia and New Zealand, SVG is particularly suited to cool climate fruit, giving quality definition and tight structure to Sauvignon Blanc, and has general application to fresh fruity styles. May exhibit some estery and savory notes immediately after fermentation. Has a moderate impact on mouthfeel, and capable of partially degrading malic acid (approx. 25%). Also increases citrus, tropical fruit and fl oral notes in neutral varieties. Properly integrated nutrition (including Go-Ferm Protect at rehydration), and raising fermentation temperature to 20°-22°C near end of ferment is highly recommended to enable steady finish.

Suited to early drinking white and red styles; its reliability in fermenation favours upfront expression of aromatics.
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.
Developed with the objective to obtain an aromatic yeast strain adapted to reveal varietal aromas during fermentation of white and rose wines. High aromatic potential; targeted for fruity 3MHA thiols with mouthfeel and longer, better aromatic intensity.
