Rezumat

Climate has an important influence on the growth and development of grapevine. The main climatic conditions (temperature, insolation, precipitation) have a positive effect on the growth and fruit setting when are at the optimum level. The climatic index for Târnave Vineyard in experimental years registered values which state the different climatic conditions. The aim of this study was to analyse the quality of wine obtained from three clone grapevine, created at R.S.V.E. Blaj (Fetească Regală 21 Bl, Sauvignon Blanc 9 Bl and Muscat Ottonel 12 Bl). The wine samples were obtained from wine production under local climatic conditions of Târnave Vineyard, Romania. The oenological analysis of wines showed that the highest alcohol content was recorded for Sauvignon Blanc 9 Bl clone (12.91% vol. and 12.67 % vol.), in both experimental years. The highest level of acidity was registered for Fetească Regală 21 Bl (7.65 g/l tartric acid) and the lowest acidity for Muscat Ottonel 12 Bl wine (5.25 g/l tartric acid). The level of free SO2 and total SO2 in wines was significantly different between samples. The Pearson correlation coefficient was calculated for each analyzed parameter and the most relevant correlations were between alcohol and sugars in must; alcohol and dry extract; sugars in must and dry extract and sugars in must and 100 berries weight. The quality of the wine produced in the Blaj Wine Center of Târnave Vineyard is directly contingent on oenological parameters and also by the climatic conditions of the year.
