Abstract:V grozdju sorte 'Rebula' (Vitis vinifera L.) nekateri vinarji odkrivajo vedno večji potencial, vendar so poleg osnovne surovine (grozdja) za končno kakovost pomembni tudi primerno izbrani in izpeljani postopki vinifikacije ter zorenja vina. Z različnimi tehnološkimi pristopi pred in med alkoholno fermentacijo lahko bistveno vplivamo na končno aromatično kakovost vina. Na aromatični potencial vina pa lahko vplivamo tudi z odločitvami po alkoholni fermentaciji in v času zorenja vina, tudi z zorenjem vina v hrastovih sodih ali ob uporabi t.i. hrastovih nadomestkov. V diplomskem delu smo pridelali eksperimentalna vina rebula po štirih različnih vinifikacijskih postopkih ter jim nato dodali trske bodisi ameriškega ali francoskega hrasta, z različnimi stopnjami žganja lesa. Tako pridelana mlada vina smo senzorično ovrednotili in zaznali določene razlike v percepciji vin glede na različne dodatke hrastovih trsk. Vina pridelana z dodatkom hrastovih trsk so degustatorji senzorično ocenili bolje kot kontrolna vina. Iz tega lahko sklepamo, da je dodatek hrastovih trsk izboljšal celokupni vtis vina. Bistvenih razlik med vini glede na poreklo hrastovih trsk (ameriški srednje žgan in francoski srednje žgan) degustatorji niso zaznali.

Title:The effect of the use of different oak chips on the aromatic characteristics of Rebula wine
Abstract:In the grape variety 'Rebula' (Vitis vinifera L.), most winemakers are discovering increasing potential in rebula wines. In addition to good and healthy grapes, there are other factors influencing wine quality, such as different winemaking decisions and procedures. We can influence the aromatic potential of wine before and during fermentation or in the later stages of winemaking, mainly by maturing wine in oak barrels or using oak substitutes. In our experiment, wine was produced using four different vinification procedures with the addition of oak chips from American or French oak with different toasting levels. All wines were sensorically evaluated, and we noticed differences in perception between different oak chip additions. The wines with added oak substitutes where in general evaluated better the without them, from that we can conclude that the addition of oak chips contributed to the final overall impression of wine. The sensory evaluations were better with the addition of oak chips. No significant differences were detected between the wines according to the origin of the oak chips (American medium-toasted and French medium-toasted).
