The objective of the present study was to evaluate the influence of climate variability of the last three years, namely 2020- 2022, on grape quality and implicitly of obtained wines from two varieties for white and red wines created at the Murfatlar Research Station, Columna and Mamaia. The increase in average annual temperature values by approximately +2.0°C compared to the reference period (years 2000-2019) in the months of February and March, correlated with the lack of precipitation, contributed to the advance the moment of vine budding and flowering, on average by 5-7 days. It was also observed a tendency for early ripening of the grapes (harvesting taking place 5 days earlier for the Columna variety and 7 days for Mamaia variety). The quality of the grapes highlighted by the content of sugars, total acidity and pH, showed significant differences in the three years under study, the sugar concentrations at the time of harvest reaching over 190 g/L, allowing the wines to be classified in the category of quality wines with controlled designation of origin DOC Murfatlar; the best results were obtained in 2022 with values of 208.7 g/L for the Columna variety and 210.8 g/L for Mamaia variety.References
