Climate change involves the adaptation of crop systems to the effects of climate variability, which influence vines, given the dependence of weather changes during the growing season, as well as increasing the duration and intensity of meteorological phenomena. The researches were carried out in the Valea Călugărească viticultural center within three viticultural plantations with the varieties Sarba, Negru aromat and Feteasca neagra. In the last the 25 years, the climate has changed in the meaning that heating resources increased and the rainfall resources decreased. These changes in the viticultural climate have determined an earlier development of the vegetative phenophases, especially the early phenophases and grape ripening (by approximately 7-14 days), which has particularly influenced the quality of grape production. Regarding the yield of grape production, it was found that the average rate of decrease was 0.86 kg/vine, the loss of acidity by 0.99 g/l and a higher accumulation of sugar 30-60 g/l.
