The Dragasani vineyard is one of the most ancient existing in Romania beingfamous for obtaining red and white wines of the highest quality. The present studyhas performed during five years (2005-2009), focusing on the anthocyanin profiles ofthe autochthonous Novac grapevine cultivar, in comparison with Cabernet Sauvignoncultivar which, also provides wines of high quality. The obtained results put intoevidence, a special potential and chromatic structure in case of the grapes and winescharacteristics for these autochthonous cultivars, which are very closed to thoseshown by the Cabernet Sauvignon. For all the cultivars studied, the amounts ofcationical flavidium within the anthocyanin matter do keep continuously wasgrowing, while acidity decreased and glucides was accumulated. However, at somemoment, these synthesis indices of the cromatical structure’s quality begin to decline.Depending of the viticultural year it is the genetical nature of the respectiveanthocyanin pigments to differentiate through the involvements of each of the 3categories of pigments (yellow, red or blue). During the wine’s evolution (maturationand aging), due to the modification of its cromatical structure, the ratio between theyellow and red pigments does confer to the wine a colour nuance which continues toincrease, significantly improving the wine’s visual attraction. For the autochthonousgrapevine cultivars for red wines, their antocyanins potential their respectivequalities do enable us to state that on the basis of the quality of the raw materials,wine types of high qualities could be created, being so endowed that they could bearas well an origin denomination.
