Phenolic profiles of riesling wines originating from different terroirs of the Czech Republic

Popis výsledku v původním jazyce

Riesling belongs to the main grapevine varieties cultivated in the Czech Republic in cool climate viticultural conditions. In this study, 34 varietal Riesling wines from fi ve wine-growing regions in the Czech Republic were investigated. Seventeen phenolic compounds belonging to hydroxybenzoic and hydroxycinnamic acids, stilbenes and fl avan-3-ols were analysed by means of HPLC. Th e study proved that the majority of the assessed phenolic compounds is not infl uenced by vintage year but only by geographical origin. Th e obtained analytical parameters were evaluated for this purpose by CVA (canonical variate analysis). Th e following phenolic compounds may be used to identify the geographical origin of Riesling wines: p-coutaric acid, trans-resveratrol, cis-resveratrol, (+)-catechin and (-)-epicatechin. Most of these phenolic compounds have their origin in grapes and thus have a close relation to the geographical origin.
