Blatina is red wine grape variety primarily grown in the Herzegovina region of Bosnia and Herzegovina. It has a functional female flower (auto-sterile), and for that reason it is always cultivated in plantations with other varieties such as Alicante bouschet (Kambuša), Merlot, and Trnjak, which at the same time pollinate Blatina. During the period of insemination, because of the rain, it can fail in giving fruits, and it is then called "praznobačva" (empty barrel). Blatina can produce dry red wine with 12 to 13.5% of alcohol, 5 to7 g/l of total acidity, 25-32 g/l of extract. It has a dark ruby red color.
