This study aimed to describe quality and potential health benefits of three Vranac wines obtained from new grape clones (CI, CII and CIII) recently developed and recognised. In this aim, their phenolic profiles, anti-2,2-Diphenyl-1-picrylhydrazyl (DPPH) radical activities along with metal compositions were analyzed. Compared with the commercial one, CII and CIII Vranac wines were found to contain both higher contents of total phenolics, flavonoids and monomeric anthocyanins as well as anti-DPPH radical activities. The most abundant phenolics were gallic acid (8.88-16.36 mg/L), catechin (12.42-24.35 mg/L) and epicatechin (4.30-7.79 mg/L). Finally, the metal content of all the analyzed samples was within the toxicological safety limits. Taken all together, Montenegrin Vranac wines represent a rich source of both phenolics and minerals exhibiting promising antioxidant potential. CII and CIII wines can be considered for commercialising due to their high amounts of gallic acid, catechin and... epicatechin, significant K/Na ratios and favourable contents of essential metals making them products with health added values.
