The smallest of Slovenia’s wine regions with just under 3000 hectares cultivated and an annual production of some 10m litres, Posavje (or the lower Sava river valley) is most closely associated with the light, fresh and slightly sour Cviček wine from the district of Dolenjska, which locals have the not undeserved reputation of drinking like water. The smaller districts of Bizeljsko-Sremič and Bela Krajina are located along different segments of the Croatian border, and are two of the more charming places to visit in Slovenia, with many castles offering Games of Thrones-esque wine tasting experiences within their medieval walls, and the so-called Repnice (turnip cellars) of Bizeljsko being one of the most unique wine destinations anywhere in the world. The region is also known for its Turizem v Zidanicah initiative (or Vineyard Cottage Tourism), through which restored traditional stone cottages located directly in the vineyards can be rented for quite reasonable prices.
