Antonopoulos produces wines from Peloponnesos, the ancient heartland of southern Greece. The winery focuses on indigenous Greek varieties, drawing on the region's distinctive terroir and viticultural heritage. Moschofilero, a white grape native to the Peloponnesos, forms the backbone of the portfolio. Gris De Noir, made from Moschofilero, stands as the flagship expression, while the varietal Moschofilero and Malagouzia—another Greek white of note—round out the core range. These wines have been assessed by major critics including Wine Spectator, Wine Advocate, Wine Enthusiast, and Falstaff, reflecting the international recognition of the winery's work with Greece's native grapes.
