The research and analyzes were carried out in 2020-2022 at SCDVV Drăgăşani in the ampelographic collection, and at the Cluj Napoca wine analysis laboratory. The wine grape cultivars analyzed and studied were 'Crâmpoșie', 'Romanie', 'Slaviţă', 'Teişor', 'Bătuta neagră', 'Negru mare', 'Negru vârtos', 'Negru Românesc', grape cultivars that are part of the national collection of germplasm of the Drăgăşani unit. The polyphenols, ascorbic acid, tartaric acid and heavy metals present in the wine were determined, both in the treated and untreated wines of these studied cultivars. Statistical calculations were performed for these wines using statistical indices such as: mean, variance (s2), standard deviation (s) and coefficient of variation (CV %). Statistical significance was determined using the "Multiple comparison test-Tukey Multiple Range Test Procedure (p<0.05)" method. The analyzes performed have shown that these wines are of high quality, the heavy metals in the wine do not exceed the normal limits, so these wines can be successfully classified as DOC and IG wines.
