Graphycal Abstract: The physicochemical properties, phenolic composition, and antiradical activity of eight Moldovan dry red wines have been investigated to identify the key determinants of their radical scavenging capacity. Total phenolic content varied between 1.40 and 2.27 g GAE/L, with the highest values recorded in Gamay (Beaujolais), Codrinschii, and Saperavi wines. Gamay (Beaujolais) exhibited the highest anthocyanin content (1.256 g M3GE/L) and antiradical activity (1.94 g AAE/L), while Codrinschii wine showed the greatest proanthocyanidin content (0.36 g CE/L). The antiradical activity correlated most strongly with the total phenolic content (R²= 0.9854), anthocyanins (R²= 0.5739), proanthocyanidin’s content (R²= 0.4717) and free SO₂ (R² = 0.4216).
