Product details

Isolated from Cornas area of the Rhône Valley by the Institut Coopératif du Vin (ICV). Originally selected for the fermentation of Grenache, ICV GRE particularly benefits red wines where an up-front fruit character is desired. Also suited for rose and white table wines. A quick starting steady fermenter, ICV GRE is recommended for a range of varieties including Cabernet Sauvignon, Cabernet Franc, Grenache, Barbera, Merlot, Nebbiolo, Sangiovese and Shiraz. Used with short skin contact regimes (3 to 5 days), ICV GRE tends to reduce vegetal and undesirable sulphur components in varieties such as Merlot, Cabernet, Grenache and Shiraz. In Australia, ICV GRE has been found to add depth to Grenache, where the alcohol is less than 14% v/v. In fruit focused whites made from Chenin Blanc, Riesling, Chardonnay, Viognier, Gewurztraminer and Pinot Gris, ICV-GRE results in fresh fruit characters with significant fore-mouth impact. The yeast promotes spicy, strawberry and confectionary characters with estery notes. Enhanced production of caproate, caprylate, laurate etc reinforces the fruit aroma of red wine
