Effect of skin contact on the antioxidant phenolics in white wine

摘要

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 diret 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 glucosde isomers were the highest found so far in white wine.
