Aromatic characterization of croatian white autochthonous grapevine cultivars
Numerous volatile compounds of grape berries play a major role in the aroma of the future wine. Despite the significant effect of different environmental conditions and management practices, grapevine cultivar has a dominant impact on content and composition of volatile compounds in white wines. The significant attention given to the local grapevine cultivars could present a new wine market trend which would help their promotion and revitalization. Since wine aroma largely affects the quality and value of white wines it is necessary to perform detailed aromatic characterisation of neglected cultivars before the final assessment of their potential for modern wine production. So far, 125 autochotonous grapevine cultivars were found in Croatia. Dalmatia, the costal part of Croatia, is especially rich in autochthonous grapevine cultivars. However, only a couple of these have a greater economic value. The aim of this study was to evaluate the volatile compounds in 24 rare white autochthonous grapevine cultivars for the first time. The volatile compounds represented by monoterpenes, norisoprenoids and C6-compounds were detected and quantified using GC-MS method. According to the investigated compounds, highest content of monoterpenes was determined in cvs. Silbijanac (27, 59 g/kg), Prc (22, 63 g/kg) and Gegic (21, 30 g/kg) compared to the other investigated varieties. The content of the norisoprenoids analyzed was higher in Silbijanac (1, 1 g/kg), Trisnjavac (0, 99 g/kg) and Marastina (0, 95 g/kg) than in other varieties investigated. The highest content of C6-compounds was detected in Malvasija dubrovacka (32, 38 g/kg) and Marastina (22, 53 g/kg). Based on these results, most varieties showed good potential for white wine production. This study presents a step-in characterization of Croatian autochthonous grapevine varieties. However, these results showed that these rare varieties can become a good alternative to the most prevalent grapevine varieties used in Croatia.
