Aromatic profiles of young wines from berries at different heights on grapevines

Abstract The differences among young wines from berries at 3 heights (fruit-zone 1 (FZ1): 140-200 cm above the ground; FZ2: 80-140 cm; FZ3: 20-80 cm) on Vitis vinifera L.cv Merlot and Chardonnay were assessed to evaluate the influence of berry-heights on the final wine quality. Stir bar sorptive extraction coupled with gas chromatography–mass spectrometry (SBSE-GC/MS) was used to analyse the characteristics of wine aromas. The results revealed that berry-heights exert significant influence on ethyl octanoate, isoamyl acetate, ethyl hexanoate, and ethyl butanoate in various- FZ Merlot wines a...
