Fantelli produces wines from Mendoza, Argentina's premier wine region. The winery focuses on Malbec, the varietal that defines the region's identity—deep, structured, and rich with dark fruit character. The Serie Magno Gran Reserva and Serie Magno Malbec represent the upper tier of the portfolio, while a core Malbec offering rounds out the range. Wine Enthusiast and Wine Spectator have rated these wines, reflecting their presence in the critical conversation around Argentine Malbec.
