With 4,300 ha/10,625 acres of vines, this is the smallest and least important wine region and PGI in Slovenia, producing slightly more reds than whites. Production is widely dispersed and bulk wine prevails. Posavje is divided into three wine districts or PDOs. Bizeljsko Sremič is known for sparkling wine Bizeljčan (white and red) and the highly acidic local white Rumeni Plavec. Bela Krajina can produce the best Rumeni Muškat (muscat blanc à petits grains) in the country and some solid Modra Frankinja (blaufränkisch). It is home to the light red pdo blend Metliška Črnina and white PDO wine Belokranjec. Dolenjska is home to the highly popular Cviček, a light, pale ruby, highly acidic blend of red and white grapes, usually Žametovka and Kraljevina. Other grapes planted in this region are Sauvignon Blanc, Chardonnay, Beli Pinot, Sivi Pinot, Renski Rizling, Traminec, Šipon, Ranina, Neuburger, Modri Pinot, Šentlovrenka (st-laurent), Gamay, Zweigelt, and Rdeča Žlahtnina (red Chasselas).
