Slovenian wine is wine from Slovenia. Viticulture and winemaking has existed in this region since the time of the Celts and Illyrians tribes, long before the Romans would introduce winemaking to the lands of France, Spain and Germany. Today Slovenia has more than 28,000 wineries making between 80 and 90 million litres annually from the country's 22,300 ha of vineyards. About 75% of the country's production is white 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. Most of the country's wine production falls under the classification of premium (vrhunsko) wine with less than 30% classified as basic table wine (namizno vino). Slovenia has three principal wine regions: the Drava Wine-Growing Region, the Lower Sava Wine-Growing Region, and the Littoral Wine-Growing Region. 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. History 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. By the Middle Ages, the Christian Church controlled most of the region's wine production through the monasteries. Under the rule of the Austro-Hungarian Empire, privately owned wineries had some presence in the region but steadily declined following the empire's fall and the beginning of Yugoslavia. By the end of the Second World War, co-operatives controlled nearly all of the region's wine production and quality was very low as the emphasis was on the bulk wine production. The exception was the few small private wineries in the Drava Valley region that were able to continue operation. In 1967, the government established the PSVVS (Business Association for Viticulture and Wine Production) which established testing practices for quality assurance and issued seals of approval for wines that met the organization's standards. In 1991, Slovenia was the first Yugoslav republic to declare independence. While the wine industry, as did other sectors of the Slovenian economy, experienced some decline following the turmoil of the Yugoslav wars, the region's strong ties to the West allowed the industry to quickly rebound.
