Salta Province in Argentina's northwest; extreme altitude viticulture at 1,700–3,000m — the world's highest-altitude commercial vineyards. Torrential sunshine (300+ days), dramatic diurnal variation (up to 25°C), and rare rainfall. Torrontés Riojano (Argentina's white signature) thrives here; also high-altitude Malbec, Tannat, and Cabernet Sauvignon with distinctive mountain character. Sand-silt soils on ancient alluvial fans.
