STUDIES REGARDING THE IMPACT OF THE ORGANIC AND CONVENTIONAL AGRICULTURAL SYSTEM ON THE WINEMAKING VALUE OF SOME VARIETIES FOR RED WINES.

Since ancient times to present, grapes have been important to man, as they were considered to be healthy food due to their phytonutrients: polyphenol antioxidants, vitamins and minerals. The preliminary researches highlight the health-related benefits of red grapes, due to their antioxidant, antiseptic and anti-inflammatory properties. Starting from this information, compared researches have been conducted so as to highlight the evolution of some biological, technological and biochemical properties of three varieties of grapes for the red wines: Feteasca neagra, Pinot noir and Merlot, in two conventional and organic agricultural systems. The yield was analysed in both systems and the results showed some differences. Special attention has been attached to the polyphenol potential of the varieties. The polyphenols have a good potential to be introduced in human medicine as primary compounds of several medicines. The studies were carried out in 2017 at the French-Romanian Estates, where the organic agricultural system was applied, and the Research and Development Institute for Viticulture and Oenology Valea Calugareasca, which uses a conventional agricultural system.
