Zagreus Winery is located in the heart of the Upper Thracian Plain — one of the most favorable regions for the development of viticulture in Bulgaria. The Kostadinov family started business with 250 decares of Mavrud in 1998. Now they own 1200 decares of vineyards where they grow Mavrud, Syrah, Cabernet Sauvignon and Merlot. The vineyards are certified as organic.
