Slovenian wine

Almost all of the wine is consumed domestically with only 6.1 million L a year being exported—mostly to the United States, Bosnia and Herzegovina, Croatia, and lately the Czech Republic.

[2] In 2016, a research study based on DNA profiling and historical ampelographic sources showed that two international varieties of red grape, the Blaufränkisch and the Blauer Portugieser, likely originate from the Styria region of modern Slovenia.

[3] Unlike many of the major European wine regions, Slovenia's viticultural history predates Roman influences and can be traced back to the early Celtic and Illyrian tribes who began cultivating vines for wine production sometime between the 5th and 4th centuries BC.

To the west is Italy and the Adriatic Sea, Hungary to the east and Croatia forms the southern border.

Some common viticultural hazards in the region include spring frost, drought during the growing season and summertime hail.

The Brda district borders the Italian wine region of Friuli-Venezia Giulia with the Gorizia Hills Denominazione di origine controllata (DOC).

[2] The Koper district on the Istrian peninsula along the Adriatic coast is the warmest wine region in Slovenia.

The Karst plateau district, located near the Italian city of Trieste, is known for the wine style Teran which is a very dark, highly acidic red wine made from Refosco planted in the region's red iron-rich soil.

[5] The Vipava Valley district specializes in light, crisp white wines made from the local Pinela and Zelen grapes.

Other grapes found throughout the Littoral region include Barbera, Pinot blanc (Beli Burgundec), Cabernet Franc, Cipro, Glera, Klarnica, Laški Rizling, Maločrn, Muscat, Syrah, and Vitovska Grganja.

The Lower Carniola district is known for its production of Cviček made from a blend of white and red wine grapes, most commonly Kraljevina and Žametovka.

The Ljutomer-Ormož district includes the village of Jeruzalem which is known for white wine made from Dišeči Traminec and Ranina.

However the emphasis on higher quality wine production has encouraged more vineyards to switch to a Guyot style of vine training.
