As Chile, Argentina has a big latitudinal range (24°S-38°S), and diverse topography, meaning that the climate varies.
The country is protected by the Andes meaning generally warm to hot contintental climate dry, and made even drier by drying winds such as the Zonda.
2 important factors grape growing in Argentina:
Altitude : increasing diurnal range (the Northern Province of Salta lies around 3000m8) elongating the growing season, and leading to high solar radiation (=high tannins and anthocyanin°. The highest vineyard are found North and in Casablanca (Uco at around 1500 m) and the lowest are located in the Southern Patagonia.
Rivers : Except on El Nino years, Argentina is quite arid and most regions suffer from drought, hence the vineyards are planted next to rivers (like the Mendoza and tributaries) allowing for irrigation (also provided by snowmelt from the Andes. This also means, than in general Argentinian soils are alluvial, rich and diverse leading to diverse flavor profiles.
The main player in Argentina is the famous Malbec, representing about 20% of all surface planted, expressing itself differently according to microclimates and soils.
Bonarda follows, creating mostly high yielding, fruity easy drinking wines in the warmer areas of San Juan and Mendoza – However, on older vines Bonarda shows quite some promise in Maipu and Luyan de Cuyo.
International varieties such as Cabernet, Syrah and Tempranillo also have an important role, whether as blends or increasingly single varietals.
Finally, Argentina also produced some whites,: Pedro Gimenez, for the cheapest, most neutral and domestically consumed.
Torrontès is the most distinctive one but produces different qualities of wines –
As its early ripening, it doesn’t do its best in the warmest sites of la Rioja or San Juan resulting in heavy and slightly bitter wines, but has built quite a reputation in high altitude- yield controlled vineyards (Cafayate, in Salta, or Uco in Mendoza) providing fresh fruity and floral whites.
