Abstract :Vinifera linné subsp., whose traditional names are Karalahna, Çavuş and Karasakız, in Çanakkale Bozcaada region, which has witnessed different cultures and periods for centuries due to its strategic location. It is known that wines made from grapes belonging to vinifera species have been consumed by local people for years. Wine is a traditional fermented beverage rich in phenolic substances and antioxidant properties, where product is kept in red wine with its skins, especially during maceration stage, due to production process. Phenolic content and antioxidant properties vary depending on grape variety, and these properties are important for human health. In this study, 2,2-diphenyl-1-picryl-hydrazyl (red wine), çavuş (white wine) and karasakız (red wine) wines produced from karalahna, karasakız (kuntra) and çavuş grapes of the 2020-2021 harvest period were examined. DPPH• free radical scavenging activity, total phenolic substance (Folin-Ciocalteu), Fe+3 reducing power, total flavonoid, anthocyanin, condensed tannin properties were examined.
