Mil Piedras produces wines from Mendoza, Argentina's premier wine region. The winery works with the classic grapes of the region—Cabernet Sauvignon, Malbec, and the white varietal Viognier—translating the terroir of the Andes foothills into bottle. The Cabernet Sauvignon leads the portfolio, followed closely by offerings in Viognier and Malbec. These wines have been assessed by Wine Spectator, Wine Enthusiast, and Decanter, reflecting the winery's engagement with international critical standards. Mendoza's high-altitude vineyards, with their marked diurnal temperature swings and mineral-rich soils, shape wines of structure and clarity—qualities evident across Mil Piedras' range.
