Blatina 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 ‘praznobacva’ (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. Aged in both stainless steel and oak barrels, Blatina will often exhibit aromas and flavors that are spice and coffee-driven. Longer aging will often result in dry chocolate flavors as well. Production is focused in the area south of Mostar around the towns of Citluk, Medugorje, Ljubuški, and Capljina.
Žilavka is a white wine grape variety planted primarily in the Mostar region of Herzegovina (southern part of Bosnia and Herzegovina). As a varietal, Žilavka is known for its nutty aroma and flavors. Once widely planted throughout the former Yugoslavia, Žilavka is today mostly a minor blending grape that can be found in some Croatian, Macedonian and Slovenian wines. Žilavka is also known under the synonyms Mostarska, Mostarska Žilavka, Žilava Hercegovacka, Žilavka Bijela, and Žilavka Mostarska. There are other, smaller varietals such as the red variety Vranac, which is grown much more in neighboring Montenegro, but Žilavka and Blatina are by far and away the most common and well-crafted wines of the region.
