There is an increasing interest in producing grapevine and wine in Poland. Therefore, new cultivars with both economical and nutraceutical properties are sought. The aim of the study was quantitive characteristics of Vitis vinifera cultivars grown in southern Poland (Garlica Murowana near Kraków). The material used for this experiment was five grape cultivars: Jutrzenka, Seyval Blanc, Rondo, Marechal Foch and Muskat Odeski. Total acidity was measured with potentiometric method, data expressed as a tartaric acid, soluble solids content with a refractometer (%), total poliphenols spectrophotometric method (g of gallic acid equivalents L-1), Ferric Reducing Antioxidant Power (FRAP expressed as μmol L-1) and elements: Ca, K, Na and Zn using atomic absorption spectrometry. Among all investigated cultivars Marechal Foch and Rondo (red fruits) were rich in poliphenols (36,8 and 30,1 g GAE L-1 respectively), FRAP (16210 i 6585 μmol L-1), as well as measured elements. White berry cultivar Jutrzenka had its parameters closer to red berries than white ones. Seyval Blanc revealed the lowest content of measured constituents.
