20.500.12556/DKUM-68635 Chemometric characterization of Slovenian red wines Total phenolic (TPC), flavonoid (TFC) and tannin (TTC) contents, total $SO_2$, total acids, pH, and reducing sugars were measured in twenty five Slovenian red wines from three key wine producing regions, Podravje, Posavje and Primorska. The results were chemometrically analysed and the wines were classified according to wine growing region and vine variety. Principal component analysis proved that TPC, TFC and TTC contents were primarily responsible for variation in the wines. Additionally, linear discriminant analysis (LDA) was performed and resulted in the satisfactory classification of samples by both vine variety and region. Vsebnost skupnih fenolov (TPC), flavonoidov (TFC) in taninov (TTC), kakor tudi skupni $SO_2$, skupne kisline, pH, reducirajoči sladkorji so bili določeni v petindvajsetih slovenskih rdečih vinih iz treh ključnih vinorodnih območij: Podravja, Posavja in Primorske. Rezultati so bili kemometrično ovrednoteni, vina pa razvrščena glede na vinorodno območje in sorto vinske trte. Metoda glavnih osi je pokazala, da so vsebnosti TPC, TFC in TTC v prvi vrsti odgovorne za razliko med vini. Z rezultati linearne diskriminantne analize (LDA) pa smo ugotovili, da so analizirani parametri odvisni tako od sorte vinske trte kot tudi od vinorodnega območja.
