Argentine wine, as with some aspects of Argentine cuisine, has its roots in Spain. During the Spanish colonization of the Americas, vine cuttings were brought to Santiago del Estero in 1557, and the cultivation of the grape and wine production stretched first to neighboring regions, and then to other parts of the country. Argentine wines started being exported during the 1990s, and are currently growing in popularity, making it now the largest wine exporter in South America. Due to the high altitude and low humidity of the main wine producing regions, Argentine vineyards rarely face the problems of insects, fungi, molds and other grape diseases that affect vineyards in other countries. This allows cultivating with little or no pesticides, enabling even organic wines to be easily produced. There are many different varieties of grapes cultivated in Argentina, reflecting the country's many immigrant groups. The French brought Malbec, which makes most of Argentina's best known wines.
