Bulgaria, located south of Romania and north of Turkey and Greece, has five major wine regions. In the south, the Thracian Valley, also known as the Thracian Lowland, enjoys both a continental climate in the northern sector, as well as a Mediterranean climate in the southern half. The most famous wine from the Thracian Valley is Mavrud, named for the eponymous variety that delivers a wine with very deep color as well as pronounced tannins. In an effort to make their wines more marketable, producers from Bulgaria have lately been planting recognized varieties such as Cabernet Sauvignon (the most widely planted variety in the country), Merlot, Chardonnay and Riesling.
