Bulgaria Wine Regions 3D Map: The Five Traditional Regions

The Thracian Valley, Struma Valley, Danubian Plain, Rose Valley, and Black Sea coast in full 3D terrain.

This interactive 3D map shows Bulgaria’s five traditional wine regions on real terrain: the Danubian Plain in the north, the Black Sea Coast in the east, the Rose Valley below the Balkan Mountains, the Thracian Valley in the south and the Struma Valley in the southwest, drawn in 3D by SommGeo. Tilt and fly over the Balkan, Rhodope and Pirin mountains, check elevation and slope, and click any region for its grapes and character. The interactive map is part of SommGeo membership, which starts with a free 15-day trial.

• Regions on the map: The five traditional wine regions, every boundary clickable
• Legal regions: Two PGIs, the Danube Plain and the Thracian Lowlands, with 52 PDOs inside them
• Warmest region: The Struma Valley, with Mediterranean influence near the Greek border
• Most important region: The Thracian Valley, heartland of Mavrud and Rubin
• Rose Valley: Named for its rose fields, and known for aromatic whites and Red Misket
• 3D tools: Tilt and rotate the terrain, elevation and slope readouts, daylight and shadow animation and a weather overlay

While Bulgaria has roughly 52 registered PDOs, the names you’ll actually encounter on bottles and in conversation are these broader, unofficial overarching regions. They don’t carry legal designation status, but they describe the geographic and climatic zones that define Bulgarian wine in practice. The country splits along the Stara Planina (Balkan Mountains), which run east to west and create a clear divide: continental and flat to the north, warm and sheltered to the south, Mediterranean in the far southwest, and maritime along the Black Sea coast. This 3D Fast Map shows those overarching regions, and the terrain makes the dividing lines between them visible at a glance.

Key Regions in Focus

Thracian Valley

The Thracian Valley is Bulgaria’s largest and warmest wine-producing zone, a broad lowland stretching across the south-central part of the country between the Stara Planina to the north and the Rhodope Mountains to the south. Elevations on the valley floor sit between roughly 100 and 300 meters (328 and 984 ft), with vineyards climbing the surrounding foothills. The sheltered position and warm continental climate make this the center of Bulgarian red wine production. Mavrud, an indigenous variety with deep color and firm tannins, is concentrated around Plovdiv and Asenovgrad. Cabernet Sauvignon, Merlot, and the Bulgarian crossing Rubin (Nebbiolo x Syrah) are also widely planted across the zone.

Struma Valley

In the far southwest, the Struma River valley runs north from the Greek border through a narrow corridor between the Pirin and Maleshevska mountain ranges. This is the only part of Bulgaria with a genuinely Mediterranean climate influence: warm, dry summers and mild winters, with the river valley funneling warm air up from the Aegean. The town of Melnik sits at the heart of the zone, and the local grape, Shiroka Melnishka Loza (Broad-Leafed Melnik), produces medium to full-bodied reds with earthy, spiced character that are unique to this area. The terrain here is visibly different from the rest of Bulgaria in 3D: steep, arid, and hemmed in by mountains on both sides.

Danubian Plain and Rose Valley

North of the Stara Planina, the Danubian Plain stretches flat toward the Danube, which forms Bulgaria’s border with Romania. The climate is more continental than the south: colder winters, hot summers, and wider diurnal temperature swings. Gamza (known as Kadarka in Hungary) is the traditional red variety here, alongside Muscat Ottonel, Dimyat, and international plantings of Cabernet Sauvignon and Chardonnay. Between the Danubian Plain and the Thracian Valley, the Rose Valley (Sub-Balkan region) occupies a transitional zone nestled between the Stara Planina and the Sredna Gora mountain range. Named for the rose oil production the area is famous for, the valley’s sheltered position and moderate climate produce both whites and reds, with Muscat and Red Misket among the characteristic varieties. The Black Sea coast, along Bulgaria’s eastern edge, adds a maritime-influenced zone where Dimyat and Muscat Ottonel benefit from the moderating sea air.
