Bulgaria does not have AOP (Appellation d’Origine Protégée) and AOC (Appellation d’Origine Contrôlée) areas primarily because these specific designations are part of the French system of geographical indications. Bulgaria uses Protected Geographical Indications (PGI) and Protected Designations of Origin (PDO), which align with European Union standards but reflect Bulgaria’s unique winemaking practices and traditions.
European System of Geographical Indications

The European Union has established a system to protect and promote regional food products and wines through designations like AOP/PDO and IGP/PGI:
- PDO (Protected Designation of Origin): Equivalent to AOP, ensuring that products are produced, processed, and prepared in a specific geographical area using recognized know-how.
- PGI (Protected Geographical Indication): Similar to IGP, indicating that at least one stage of production, processing, or preparation occurs in the designated area.
Bulgarian Wine Designations
Bulgaria uses its designations within this European framework:
- PGI (Protected Geographical Indication): Covers larger geographical areas with more flexible criteria, allowing various grape types and production methods and promoting wines linked to a specific region’s geographical origin.
- PDO (Protected Designation of Origin): More restrictive, ensuring that wines adhere to strict standards and are produced within specific geographical boundaries, similar to the AOP/AOC system.
Winemaking Practices
The wines’ designations and classification reflect Bulgaria’s unique winemaking practices.
- Blending of Grapes: Unlike many traditional wine regions in France, where wines are often produced from grapes grown in a specific, tightly controlled area, Bulgarian wineries frequently blend grapes from different regions. This practice introduces complexity in quality control but allows for greater flexibility and innovation in winemaking.
- Transporting Grapes: Bulgarian wineries often transport grapes over long distances to their production facilities, contrasting with the French tradition of local sourcing. This method is increasingly common worldwide but does not fit within the strict geographical limitations of AOP/AOC.
- Larger Geographical Areas: Bulgaria’s PGI regions – the Danubian Plain and Thracian Plain, encompass larger areas than France’s particular AOP regions. This broader approach accommodates the diverse terroirs and winemaking styles found throughout Bulgaria.
Bulgaria’s use of PGI and PDO designations aligns with European Union standards while allowing for the blending of grapes from various regions and broader geographical areas. This flexibility supports Bulgaria’s unique winemaking traditions and innovations, ensuring its wines reflect Bulgarian vintners’ diverse terroirs and creative approaches.
