Teran grape is a variety of red grape from Istria, Croatia. It is mostly found in western part of Istria. It is a late-ripening variety and grows in large clusters with densely packed berries. Berries have highly resistant skin and deep ruby red color. The vine requires a lot of sun but less water. It is sensitive, both to extremely strong sun (burning hazard) and to excessive humidity (botrytis). When the grapes are fully ripe and all other needed conditions are met, a very good quality red wine can be made from them. Its alcohol content is usually between 11 and 14%.
