Sažetak
The identification of the geographical origin and authenticity of Croatian wines by specific analytical methods is of importance for wine consumers and producers and the official wine control, because it will provide significant criteria for guaranteeing the protection of controlled origin, quality and authenticity. In the European Union (EU) since 1992 a data bank of stable isotope data of authentic wines produced in EU Member States has to be established each year, following the regulations No 2348/91, respectively the actual regulation No 2729/2000. Croatia as country outside the EU started to create an equivalent data bank of such analytical data of authentic wine samples in 1999. A study was carried out with two of the economically most important Croatian cultivars, Welsh Riesling (the most disperse continental white cultivar) and Plavac Mali (dominant red cultivar of Dalmatia) from two Croatian vine-growing regions. Croatia, small by surface but pedologically and climatically diverse, offers interesting possibilities for studying the influence of this diversity on the stable isotope ratios in molecules of natural products. Each cultivar samples were collected from five different locations. Samples of fresh grapes from the vintages of 1999 and 2000 were taken and processed into wine in accordance with the actual EU regulation No 2729/2000. The stable isotope ratios (D/H)I and (D/H)II of the wine ethanol were determined by SNIF-NMRÔ method ( 2H-NMR spectroscopy), the 13C/12C isotope ratio of wine ethanol and the 18O/16O isotope ratio of wine water by isotope ratio mass spectrometry (IRMS). In addition traditional chemical wine analysis of different compounds including colour pigments of red varieties and a sensory evaluation of the wines was performed for a later successful and complete authentication. The results of stable isotope ratios of hydrogen, oxygen and carbon show that a significant separation of wines originating from the southern costal regions from those produced in the continental regions is possible. The significant enrichment of the heavier isotopes in wines of the southern vine-growing areas is a result of their geographical origin and its specific climate. The preliminary results are of crucial importance for Croatia as a wine producing and exporting country, in order to have a control on authenticity and quality equivalent to the EU.
