Abstract:
This article presents the results of experiments on modifying the values of oxidation - reduction potential of phenolic compounds and chromatic indices in the red wines Cabernet - Sauvignon and Merlot produced in different wine-making regions of Moldova: Cahul, Leova (South zone) and Talmaza (South – East zone). These experiments allowed to highlight the role of cultivating zone and thermic treatment on the values of redox potentials directly influenced by the pedo - climatic conditions
