Adakarası (Turkish: adakarası, "island's black"), is a red grape variety originating in Turkey. Its most famous production place is Avşa Island, which produces about 1,500 tonnes of wine per year from the grape. As a result, the wine made from the grape is also known as Avşa. Another name for it is Adakara. Adakarsi grapes are also grown in all of the Marmara Region, (especially on the Marmara coast and in East Thrace).
The wine usually has an alcohol ratio of 12 percent and an acidity range of 6 to 7 grammes per litre.
