In years of average yield, Slovenia produces about 800.000 - 900.000 hectolitres (21.1 - 23.8 million gallons) of wine annually, on some 21.500 hectares (532.000 acres) of vineyards in three wine growing regions: Podravska, Posavska and Primorska. These are further subdivided in accordance with specifics of microclimatic conditions, soils, etc. For comparison: the total area of Slovenian vineyards is approximately the same as that of Bordeaux country, production of wine about half of that. Quality and high-quality wines dominate -- only some 30% of wine produced in Slovenia is of the table-wine category.
The quality of Slovenian wines is guaranteed by the large number of small producers. The outstanding quality comes in batches of 700 to 3000 bottles, lovingly prepared by vignerons with small and immaculately tended vineyards. The Slovenian Wine Growers and Producers Association imposes and enforces strict rules, governing everything from the types of grapes that may be grown in specific regions, to the methods for production of wines and labeling. Slovenia has always been the crossroads between north and south, east and west; travelers brought viticulture knowledge from all dominant viticulture nations. Accordingly, French, Italian and German influences are evident both in the growing and production of wines, as well as in terminology. Varietals wines are predominantly named after the grape, while blended wines frequently carry the name of the producing region; the terminology for high-quality and predicate wines is equivalent to German.
