What are some emerging wine regions in Argentina?

Even though Mendoza represents the backbone of Argentina's vine and wine production, the newcomers are not taken for granted, and regions with their indigenous terroir and advanced winemaking techniques are now widely recognized. At an altitude of 2400 metres in the northwest of the country, Salta is regarded as the “garnet-drunk” town; it produces exquisite Torrontes and malbec of the elegant and structured types. Patagonia, a trendy wine region with cool winds, is attracting attention for its naturally grown Pinot Noir or Merlot selection. In the foot of Andes is situated La Rioja and it is famous for its Bonarda and Cabernet Franc wines where the grapes are exuberant and more forward.
