Although Montenegro became a part of the Ottoman Empire at the end of the 15th century, Montenegrins maintained a high degree of autonomy primarily due to geographical position and poverty of its inhabitants in the mountainous regions who weren’t earning enough to pay taxes to the Turks. So, they didn’t have many conflicts with the Turks, but the Turks obviously left traces of their presence in Montenegro.Research on genetic diversity of grapevines in Montenegro carried out by Vesna Maraš has unveiled valuable results and provided better understanding of wine history in the Balkans. The Montenegrin and Spanish scientists analyzed 512 wild and cultivated vines from old vineyards across Montenegro and tried to determine their identity and pedigree.
The list of analized and determined varieties contains japundžak, a variety that is used both as table and wine grape. This finding is of utmost importance because until now it has been considered that Yapincak can be found exclusively in Turkey, in the region around the Marmara Sea. Therefore, this finding in Montenegro represents the most western reporting of this grapevine.
Yapincak in all probability originates from Turkey, from the province of Tekirdag / Thrace (northwestern Turkey). The grapes have characteristic red freckles and a thin skin, and show relative resistance to disease. Late variety, well adapted to warm and dry climate. There remains a mystery how this variety came from Turkey to Montenegro, but if similar research confirms existence of Yapincak (japundžak) in Serbia as well, then we can claim that Yapincak had much wider distribution in the Balkans in the past than nowadays.
