Croatia has a long-standing winemaking tradition dating back to the 5th century BC, with many indigenous grape varieties that are uniquely adapted to local microclimates and not found elsewhere. The country is divided into four main wine regions, each producing both white and red wines from native and international grapes: Istria and Kvarner: Mediterranean climate; known for the white Malvasia Istriana (Malvazija) and the red Teran. Slavonia and Danube: Cool continental climate; home to the native white Graševina. Reds include Merlot, Cabernet Sauvignon, Pinot Noir, Frankovka (Blaufränkisch), and Zweigelt. Dalmatia: Unique coastal terroir; white grapes include Pošip, Grk, Maraština, Kujundžuša, and Debit; red varieties include Plavac Mali, Babić, Crljenak Kaštelanski, and others. Croatian Uplands: Northern region known for indigenous whites like Škrlet, Pušipel, and Kraljevina, with reds dominated by Pinot Noir and Portugieser. Croatia’s wine scene is diverse, rooted in history, and rich with both traditional and international styles.
