Varietal thiols are extremely volatile and desirable wine aroma compounds that contribute to tropical fruit notes. Their concentration depends on numerous factors, from agricultural practices to winemaking procedures and storage conditions. Among them, grape variety is one of the most important factors, and diversity among clones of a single variety has also been highlighted. The aim of this work was to determine the varietal thiols in wines produced from different clones of Pošip (Vitis vinifera L.) grape. The results showed significant differences between clones, with the highest concentrations of varietal thiols detected in wine produced from clone POŠ-124. The results suggest clone selection as an important step in diversifying the styles of produced wines.

Sortni tioli su izrazito mirisni i poželjni spojevi arome koji doprinose mirisu vina aromama tropskog voća. Njihova koncentracija ovisi o brojnim čimbenicima, od ampelotehničkih i enoloških postupaka do uvjeta skladištenja. Sorta grožđa je jedan od najvažnijih čimbenika, pri čemu su utvrđene razlike i između samih klonova pojedine sorte. Cilj ovog rada bio je istražiti utjecaj klonova sorte Pošip na koncentraciju sortnih tiola u vinima. Rezultati su pokazali značajne razlike između klonova pri čemu su najviše koncentracije utvrđene u vinu proizvedenom od klona POŠ-124. Dobiveni rezultati ističu klonsku selekciju kao važan korak u proizvodnji vina različitih stilova.
