Sažetak
It is well known that different viticultural practices have an important influence on the quality of grapes, must and wine. Aiming to examine impact of partial defoliation we were measured composition of the aromatic components in the wine of Gewurztraminer, winegrowing hills of Zagreb, subregion Prigorje-Bilogora. Partial defoliation, i.e. removing of 4 (D1) and 8 (D2) basal leaves, conducted manually at veraison and grapevines without defoliation (ND-non defoliated) were used as control. Samples for analyses were taken after filtration, stabilization and bottling of wine. It was shown that the wine made from completely sun exposed grapes (D2), were the richest in the content of free volatile terpenes (FVT) and potentially volatile terpenes (PVT) respectively.
