The soils and climate of the regions are very similar to Mendoza but the unique mesoclimate and high elevation of the vineyards typically produces grapes with higher levels of total acidity which contribute to the wines balance and depth. Of the three regions, Catamarca is the most widely planted with more than 5,800 acres (2,347 ha) under vine as of 2003. In recent years the Salta region, and particularly its sub-region of Cafayate, have been gaining the most worldwide attention the quality of its full bodied whites made from Torrontés Riojano as well as its fruity reds made from Cabernet Sauvignon and Tannat.[1]
