The state of Bosna i Hercegovina, formerly part of Yugoslavia, became independent in 1992. Organised viticulture began under the rule of the Habsburg monarchy of Austria-Hungary towards the end of the 19th century. In 1886, the wine and fruit growing office was founded in Gnojnice. The wines were very popular at the Viennese court, which is why these vineyards are still called "imperial vineyards" today. A temperate continental climate prevails with hot summers and dry cold winters. The vineyards cover 6,000 hectares of vines, from which about 50,000 hectolitres of wine are produced. The vineyards are located on the coast and north of Dubrovnik in Croatia mainly around the towns of Citluk, Caoljina, Stolac and Mostar. The dominant grape varieties in terms of volume are the two autochthonous Žilavka (white) and Blatina (red). Other important red wine varieties are Cabernet Sauvignon, Krkošija, Plavac Mali and Syrah.
