A study was conducted to determine the effect of skin contact on the antioxidant phenolic composition and sensory properties of wine from Listan Blanco, a variety of Vitis vinifera grown in the Canary Islands. Compared with direct pressing of vintage, skin contact increased the levels of phenolics including those with physiological properties, and improved the sensory characteristics. The values of resveratrol and its glucoside isomers were the highest found so far in white wine.
