Known by many as Argentina's most northerly winemaking region but just south of Jujuy, Salta (25 degrees South) has relatively extensive wine exports. The reason Salta, and Jujuy, are outside the 30-50 latitude but still able to grow vines is because the cool temperatures come from the ideal heights of the vineyards here, ranging from 1700m to 2400m (tallest among vineyards in the world). Although there are not many large vineyards, Salta is considered the second most important winemaking region in Argentina after Mendoza. Malbec, Cabernet Sauvignon, Merlot, Syrah and Tannat are the dominant black grape varieties, while Torrontés is the main white grape variety. The Cafayate Valley subregion in the middle of the Cachaguíes valley of Salta is home to the finest Torrontés bottles.
