The paper’s aim was to present the maturity evolution for three grapes varieties, for establishing the correct harvest time in 2019 in Cernavoda vine Center. These were: ʻVictoriaʼ - grapes for table, ʻRiesling Italianʼ - grapes for white wine and ʻMerlotʼ - grapes for red wine, for which there were determined the moments of commercial, full and technological maturity, settling the optimum time of the grapes harvest according to the degree of ripen, which is an important factor in the quality of future wine. The data obtained indicated that the grapes ʻVictoriaʼ had reached commercial maturity in August 24, with the caracteristics: sugars - 156.7 g/l and total acidity - 3.5 g/l H2SO4. The grapes, ʻRiesling Italianʼ had reached full maturity in September 25, with the follow characteristics: sugars - 230 g/l and total acidity - 5.2 g/l H2SO4, and the black grapes ʻMerlotʼ had reached in the same time full and phenolic maturity in October 3, with the characteristics: sugars - 235 g/l, total acidity - 6.02 g/l H2SO4 and anthocyanins 1680 mg/kg. The mechanical composition of the grapes was analyzed and the uvological indices were calculated, and the conclusion was that these are adequate to each variety.
