Viamonte produces Malbec across three tiers from Mendoza, Argentina's premier red wine region. The portfolio ranges from an entry-level Malbec through a Reserva expression to the Gran Reserva, which represents the winery's top offering. Wine Enthusiast and Wine Spectator have both assessed the range. The Gran Reserva Malbec earned a 90-point average rating, while both the Reserva and standard Malbec scored 86 points on average. Mendoza's high-altitude vineyards and continental climate create conditions suited to Malbec's dark fruit character and structural depth—qualities evident across Viamonte's lineup.
