Sažetak
Continental Croatia wine region and especially Kutjevo vineyards are famous for their predicate wines production and quality. The most common grape varieties used there for different types of predicate wine are Welsch Riesling and Traminer. Ice wines, selected harvest wines and dry berry selection wines from different harvest years were examined by HPLC method to determine organic acids composition. The oldest sample was Traminer selected harvest from vintage year 1990, while the youngest wine was Traminer ice wine from harvest 2011. The dominant organic acids in all analyzed wines were tartaric, malic, citric and galactaric, ranged from 0.09 to 2.98 g/L. In most wines the difference in concentration of glucuronic, galacturonic and gluconic acids was established. The highest content of glucuronic acid was 58.4 mg/L in Traminer dry berry selection 2011. Galacturonic acid dominated in the same wine (924 mg/L), just like gluconic acid (141 mg/L).
