For mouthfeel in Mediterranean-style reds
ICV D254 was selected by the Institut Coopératif du Vin (ICV) in 1998 from Shiraz fermentations in Gallician, south of the Rhône Valley. Recommended for all red wine and Chardonnay and other barrel-fermented white wines. Enhanced mouthfeel due to its production of polysaccharides. In red wines, ICV D254 contributes to fore-mouth volume, enhanced mid-palate mouthfeel, smooth tannins and a mildly spicy finish. Red wines made with ICV-D254 may be blended with ICV D80 or ICV D21 to create more concentrated, full-bodied wines. In unripe reds, ferment 25 to 50% of the batch with ICV D254 and the balance with ICV GRE to help mask vegetative character. In Chardonnay, produces nutty aromas and creamy mouthfeel, and can be used as a complement to Lalvin ICV D47 in ChardonnayFermentation Speed
