There is a lot to discover in the wine regions of Bulgaria. However there are such a massive plantations of international varieties, you will find also indigenous varieties that are worth to taste and fall in love with.
Bulgarian Wine Regions
According to act 67/16.08.2005, the Bulgarian territory is divided into 2 main regions for the production of regional wines, namely the Danube Plain and the Thracian Lowland. However, according to the old enactment no. 162/13.07.1960 of the Council of Ministers of the Republic of Bulgaria, Bulgaria’s territory is divided into five main viticultural regions, according to the different soil and climatic conditions in the country. Those regions are: Danube Plain (North Bulgarian), Black Sea (East Bulgarian), Rose Valley (Sub-Balkan), Thracian Lowland (South Bulgarian), and Struma River Valley (Southwest Bulgarian). Each region offers specific grape varieties and wines.
The Danube Plain (Northern Bulgaria) wine region encompasses 49 distinct micro-areas and regions. It is characterized by a temperate continental climate. Its main features include hot summers and a significant amount of sunny days, as well as very cold winters. Fogs are also very common for the region. Soils are mainly black earth and grey-brown forest, as well as alluvial-meadow soils. The region covers the central and western part of the Danube Plain, the south bank of the Danube River and its appurtenance regions. The most typical white grape varieties in the region are Chardonnay, Aligote, Muscat Ottonel, Misket and Riesling. Red grape varieties in the region are mainly represented by Merlot, Cabernet Sauvignon, Pamid and Gamza. In the Danubian Plain region there is production of quality white dry wines, sparkling wines (classic technology) and quality red wines, which are characterized by rich fruity aroma and fresh taste.
The Black Sea (Eastern Bulgaria) region incorporates 32 distinct micro-regions along the Black Sea coastline and the area of Ludogorie, as well as embraces 30% of the vineyards in the whole country. It also encompasses the Varna, Burgas, Pomorie, Dobrich, Silistra, Shumen and Targovishte viticultural regions. The climate is influenced by the sea, and is characterized by hot summers, cool springs and mild winters. The autumn in the Black Sea region is warm, dry and long, which is advantageous for the accumulation of sufficient amount of sugars for the production of fine white semi-dry wines. Soils are diverse, but constitute of primarily black earth, grey-brown forest, alluvial-meadow and humic-carbonic soils. 53% of the white grape varieties are concentrated in this region, most importantly Dimyat, Muscat Ottonel, Rkatsiteli, Traminer, Riesling, Sauvignon Blanc, Chardonnay, Aligote and Ugni Blanc. Red grape varieties are mainly represented by Pamid, Merlot and Cabernet Sauvignon. The Black Sea viticultural region is characterized by the production of some of the best dry and semi-dry Bulgarian wines, which combine a pleasant fruity aroma, dense taste and elegant freshness.
The Rose Valley (Sub-Balkan) region includes 13 micro-regions. It is situated on the South of Old Mountain and constitutes of two river valleys: that of Tundja on the East and of Stryama on the West. The main viticultural centres are Sliven, Moscovec, Karnobat, Karlovo, Hisarya, Shivachevo, Yambol, and Sungurlare. The climatic and soil conditions in the region are considered to be from the most suitable ones for cultivating high quality vines. Soils are primarily brown and cinnamon forest ones. The diversity of micro-regions and soils is fascinating, but most significant is the excellent air drainage along the slopes of Middle Forest. Evidence of those excellent conditions is the fact that although the Rose Valley region is not the biggest in Bulgaria, this is where the highest quantity of wine is produced. The main grape varieties in the region are Merlot, Cabernet Sauvignon, Riesling, Red Misket, and Rkatsiteli. The region is known for its production of mainly white dry and semi-dry wines, and less red and aromatized wines. The wines have a characteristic pleasant fruity aroma, fresh and harmonic taste. The wines made from the local grape variety Red Misket are some of the best representatives of the Bulgarian white wines and are unique with their rich fruity aroma, elegant body and gentle, memorisable aftertaste.
In the Thracian Lowland (Southern Bulgaria) region the climate is temperate continental with uniform rainfalls during the whole period of vegetation. It includes 39 micro-regions, representing 60% of the red grape varieties in the country. The region encompasses the central part of the Thracian Lowland and parts of Sakar Mountain. Soils are mainly cinnamon forest, clayey and alluvial-meadow. The Thracian Lowland region incorporates many viticultural centers such as Stara Zagora, Nova Zagora, Purvomai, Chirpan, Korten, Harmanli, Svilengrad, Ivailovgrad, Lubimets, Asenovgrad and others. Most of the red grape varieties in the country are concentrated in this region, namely Merlot, Pamid, Syrah, Cabernet Sauvignon, Mavrud, Red Misket, Rubin and others. The climatic conditions, which are protected from sharp northern winds, are favorable for the production of rich, dense, memorable red wines from grape varieties such as Cabernet Sauvignon, Mavrud, Merlot, Cabernet Franc, Petit Verdot, and others. The good wines made from the local grape variety Mavrud are greatly appreciated, as they combine the aroma and the taste of small red fruit, spices and grasses. Asenovgrad, Perushtitsa, Bresovitsa, Brezovo, Karabunar and Septemvri have been recorded in historical books as serious viticultural centers that mainly manufacture the local Mavrud and Pamid. White grape varieties in the region are mainly Sauvignon Blanc, Chardonnay, Traminer and Muscat.
The Struma River Valley (South-Western Bulgaria) region is not large in size, including only 10 micro-regions and areas, but has very specific climatic conditions, which make it similar to the Mediterranean areas. There is a diversity of the soils in the region (cinnamon and brown forest soils, alluvial-meadow and mountain soils, and others). It comprises of the South-western parts of the country and encompasses Mesta and Struma river valleys. The main centres are Petrich, Sandanski, Melnik and Blagoevgrad. The influence of the Mediterranean climate, the extremely high temperatures and the relatively poor soils set the pattern for cultivating primarily high quality red grape varieties. The most typical grape varieties in the region are the local variety Melnik (wide leaf vine of Melnik), Merlot and Cabernet Sauvignon. Cabernet Franc is also present in the region. The wines of the regions are characterized by warm south tones in the aroma, with roundness in the taste and richness in the overall impressions. The wines made from the local grape variety Melnik (wide leaf vine of Melnik) have gained a lot of interest, as they are rich and have a sufficient volume, as well as gain exotic and very pleasant nuances in the taste when aged.
Climate and Soils in Bulgaria
Bulgaria’s climate, soils and temperature levels create excellent weather conditions for growing superior grapes and wine production. There is a diversity of perfectly suitable for viticultural practices natural landscapes in the country, with lush rivers and hills sloping down gradually to the costal areas, as well as with valleys and plains that are embraced by mountain ridges.
In Bulgaria, there are all four seasons- mild winter, pleasant and long autumn, hot and dry summer and blooming spring. The average yearly temperature in the country is + 14.7°C, while the average temperature between the months of April and September is + 23°C. The average temperature sum necessary for the vines is between 3500 and 3700 °С. The sum of the rainfall per annum is between 470 and 953 liters per square meter, while the sunlight per year is estimated to be between 2200 and 2500 hours in the country. On one hand, the climate in the South of Bulgaria is characterized as intermediate continental, tending to Mediterranean. On the other, Northern Bulgaria is distinguished by its temperate continental climate. The climate along the Black Sea is maritime, while the regions with an altitude of 1900-2000 meters above sea level have a climate that is mountainous.
The soils are diverse between the various regions of the country. In Bulgaria there are cinnamon and grey forest soils, humic-carbonic soils, acidic soils, fertile black earth (chernozems), mountain soils, alluvial-meadow, including both deep and shallow sandy soils, and others. They are all extremely favorable for the development of the vines, for the good maturation of the grapes and for the production of quality red and white wines.
The climate, lay and the variety of soils in the country present great opportunities for viticulture and winemaking. Bulgaria benefits from excellent nature and climate-related conditions for growing both international and traditional local grape varieties.
