The aim of the research was to determine the influence of barrique barrels of different ages on the quality of sensory characteristics of Babić, Plavac mali and Tribidrag wines. The research was conducted at the Galić d.o.o. winery from Kutjevo. The grapes used for wine production originate from Jadrtovac, a location in the surroundings of Šibenik. The organoleptic analysis of the wine was carried out using the descriptive and 100-point methods. The results of the 100 points method were processed statistically. Prior to the actual descriptive evaluation of the samples, in addition to the pre-set general descriptors, specific descriptors for each varietal wine were determined by tasting the samples. The evaluation was carried out by a panel of evaluators trained as part of the "Uncorking rural inheritance" project. Significant differences regarding the quality of aroma and the overall evaluation of the Babić wine variety were found, with the wine from the new barrique barrel achieving a better result. A statistically significant difference was found in the taste quality of Plavac mali and Tribidrag wines. The taste quality of the Plavac mali wine from a new barrel was rated as better, while the quality of the Tribidrag wine variety was better when treated from a previously used barrel.

Application of the aroma extract dilution analysis (AEDA) on a distillate prepared from freshly squeezed juice of Dornfelder grapes revealed (3 Z )-hex-3-enal and trans -4,5-epoxy-(2 E )-dec-2-enal with the highest flavor dilution (FD) factors. In contrast, in the final Dornfelder wine prepared thereof, the highest FD factors were found for 2-phenylethyl acetate, 2-phenylethan-1-ol, and ( E )-β-damascenone. However, for example, among others, (3 Z )-hex-3-enal no longer appeared as an important odorant. To monitor the olfactory changes occurring in single processing steps from Dornfelder grapes to the final wine, selected odorants in grape juice, must, and young as well as aged wine from the same batch of Dornfelder grapes were quantitated. In particular, (3 Z )-hex-3-enal and hexanal decreased considerably during mashing, while, as to be expected, the concentrations of yeast metabolites, e.g., odor-active alcohols and esters, drastically increased during fermentation. To reveal the influence of barrel aging, the odorants of the same Dornfelder wine aged in either barrique barrels or steel tanks were compared.
