Relationship between some sensory attributes and overall impression of Malvazija istarska wines produced with different vinification techniques

The aim of this work was to determine the relationship between some aroma sensory descriptors and wine quality scores of white wines made from cv. Malvazija istarska (Vitis Vinfera L.). Six different vinification techniques were carried out: control treatment – fast grape processing without maceration (BP), fast grape processing with the addition of oenological tannin (BPT), pre-fermentative cold 1-day maceration (MM1), 7 days maceration (MM7), 21 days maceration (MM21) and vinification of dried grapes (MP) of cv. Malvazija istarska. Sensory profile of wine samples was obtained using both quantitive descriptive analysis (QDA) and 100 points O.I.V/U.I.O.E. evaluation method. The results showed a positive correlation between the presence of fruit and floral aroma attributes and overall wine impression. All observed treatments contributed to the positive effect on fruit and floral aromatic profile and overall wine impression in respect to control treatment.
