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

The aim of this study was to establish the relationship between some sensory attributes and the overall impression of native Croatian red wine variety Teran (Vitis vinifera L.). Wines were produced with four different vinification techniques: control (7-days maceration, TM7), prolonged maceration 10 and 21 days (TM10, TM21 respectively), and pre- fermentation heating treatment (TPHT). The sensory profile of wine samples was obtained using quantitative descriptive analysis (QDA) and 100 points O.I.V/U.I.O.E. evaluation method. Five panelists rated the intensity of body/fullness, astringency, viscosity, aftertaste quality, and varietal typicity of taste. The results showed a positive correlation between the intensity of most taste attributes and the overall wine impression. A strong negative correlation was observed for astringency. All observed treatments, highlighting post-fermentative prolonged 21-day maceration and pre-fermentation heating treatment, contributed to the positive effect on taste profile and overall wine impression regarding control treatment.
