It was analyzed white and red wines from 5 ecological varieties cultivated in the Dragasani vineyard: Cabernet Sauvignon, Novac and Negru de Dragasani – varieties for red wines; Tamaioasa Romaneasca and Sauvignon blanc – varieties for white wines. The production of grapes in the ecological system has been analyzed, as well the sugars and acidity content in the grape. The organic wines were analyzed in terms of chemical characteristics: alcoholic strength (vol% alcohol), residual sugar content (g/L), total acidity (g/L sulfuric acid), total dry extract (g/L), acidity volatile (g/L acetic acid) and glycerol content (g/L). At the analyzed red wines, we also see the content of wines in polyphenols, tannins and anthocyanins. All analyses were performed by the standard methods (Tardea, 1980). The results of the analyzes show that, although the production of organic grapes is much lower than in the conventional system, the compositional parameters recorded higher values, which included wines in superior wines.
