 In the far northwestern corner of the country are the provinces of Catamarca, Jujuy and Salta which includes some of the world's highest planted vineyards.In the southern region of Patagonia, the Río Negro and Neuquén provinces have traditionally been the fruit producing centers of the country but have recently seen growth in the planting of cool climate varietals (such as Pinot noir and Chardonnay).Despite the total area planted declining from between 1980 and 2003, Mendoza is still the leading producer of wine in Argentina.
