Abstract: The effect of vineyard shading on the composition, sensory quality and volatile flavours of grape wines from Vitis vinifera L. cv. Pinot Noir under Bangalore conditions, a region endowed with mild tropical climate, was studied. Wines from 50 and 75 per cent shaded vineyards were found to have better sensory appeal, significantly higher titratable acidity and lower levels of phenolics than those from open conditions. The wine colour parameters viz., hue and chroma, were significantly superior in wines prepared from berries of open vineyards. Head space volatile analysis showed that wines from shaded vineyards possessed higher levels of Pinot Noir aroma varietal specific compounds such as phenyl ethyl alcohol, methyl anthranillate, methyl and ethyl hexanoate, linalool, octanoic acid, and decanoic acids. The study showed the possibility of improving Pinot Noir wine quality by vineyard shade management in warmer viticulture areas...
