Altocedro operates in San Carlos, the southernmost subregion of Mendoza's Uco Valley, where high altitude and continental climate shape wines of precision and depth. The winery focuses on Malbec and Cabernet Sauvignon—varietals that thrive in this terroir's cool nights and intense daytime sun. The Gran Reserve Malbec and Old Vine Reserva Malbec represent the house's commitment to the region's signature grape, while the Reserve Cabernet Sauvignon rounds out a portfolio rooted in classic Uco Valley character. These wines have been assessed by Wine Enthusiast, Wine Advocate, Wine Spectator, Decanter, and Falstaff. San Carlos's elevation and diurnal temperature swing produce reds with structure and aging potential—hallmarks of serious Mendoza viticulture.
