In Croatia, the nearly 880 hectares (2,175 acres) of Blaufränkisch, known as "Frankovka", represent around 2.7% of all Croatian vineyard plantings. This number is expected to rise, as many plantings previously thought to be a different variety, "Borgonja", have now been proven by DNA testing to be Blaufränkisch. Most of the Croatian plantings are found in the Kontinentalna Hrvatska (Continental Croatia) region in the northwestern part of the country and on the Istrian peninsula along the Adriatic Sea. In Serbia, most of the plantings of Blaufränkisch are found in the province of Vojvodina.
