The labelling of wines sold on the Slovenian market is governed by the EU legislation (already seen in the specific EU Guide) which in Slovenia has been implemented and applied by the provisions of the Wine Act and the Rules on the labelling and packaging of wine.
A specific requirement under the Slovenian law (which is not envisaged under the EU legislation) is that the classification by quality class shall be specified on the label (e.g. wine, sparkling wine, quality wine, quality sparkling wine, wine of superior quality, superior quality sparkling wine) except from wines with no indication of vine variety and wines with no protected designation of origin or no geographical indication. Slovenian law also requires that each Slovenian wine (from the class of quality wines with the protected designation of origin, local wines with a recognized geographical indication and wines with the designation of vine variety) shall, prior to being put on the market, be subject to appraisal procedure conducted by authorized appraisal organization.
Mandatory information on the label (to be in Slovenian language): category of grapevine product, product type name of the product, alcohol content (vol %), nominal volume (l, ml, cl), sugar content (only mandatory for sparkling wine and aerated sparkling wine), origin, an indication of the bottler for still wine and of the producer for sparkling wine, indication of traditional term for wines with the Protected Designation of Origin, or Protected Geographical Indication, name of geographical indication, serial number, name of importer for imported wines, allergenic ingredients (sulphites, milch or egg proteins), appraisal decision number (where applicable).
In addition to the above requirements, additional information may be indicated, such as geographical data (area), year of vintage, vine variety, additional statements for wines with protected geographical indication or designation of origin, wine colour, images of the protected designation of origin area (DPO) or of the protected geographical indication, indication of certain type of production, additional (traditional) indications (name of cellar, farm, winery,..), harvesting year, EU quality schemes symbols (into which the product is integrated) etc. Any misleading content is prohibited.
