In Slovenia viticulture and winemaking has existed 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.
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 Valley, Lower Sava Valley and Slovenian Littoral.
