The accumulation of anthocyanins and total phenols during ripening in cv. Probus and Cabernet Sauvignon grepe berries in Fruška Gora wine region

The anthocyanin and total phenols concentrations of Vitis vinifera cv Probus (Serbian wine grape variety) and Cabernet Sauvignon, during ripening in Fruska Gora region, were investigated. Phenolic concentration was evaluated by spectrophotometric analysis. Probus had higher anthocyanins concentration in the skin and total phenols per berry. Cabernet Sauvignon did not show big enlargement in anthocyanins content during this period. Contrastingly, anthocyanins content in Probus berry skin was increasing until harvest. Small berries of cv. Probus had colored pulp. There was a decrease in the Cabernet Sauvignon berry weight near the harvest. Optimum moment to harvest Probus was 50 days after veraison. Overall, these two varieties showed differences in anthocyanins accumulation during ripening.
