THE INFLUENCE OF CLIMATIC CONDITIONS ON OENOLOGICAL PARAMETERS OF SOME WINE CULTIVARS FROM DIFFERENT ROMANIAN VINEYEARD

A study concerning the influence of climatic conditions on the oenological parameters of wine cultivars was carried out using six wine cultivars under the climatic conditions of 2019. Wine samples were taken from Ştefăneşti–Argeş, Babadag and Drăgăşani viticultural centres. Determination of the oenological parameters has been made for the following wine cultivars: Riesling Italian, Fetească Regală, Sauvignon Blanc, Feteascǎ Neagră, Merlot and Pinot Noir. The chemical parameters were determined using a Mindray BS 200 oenological analyser and the statistical analysis of the results was carried out using the Duncan test. A correlation was made between the parameters of the six wine cultivars from the three viticultural centres, focusing on the correlations between the total polyphenols of wines and their antioxidant activity.
