With the majority of terroirs located in a strip of desert at the foot of the Andes, at first glance Argentina seems like a homogeneous country. However, this strip of desert has incredibly variable altitudes, ranging from 600 meters above sea level in the east of Mendoza and the Tulum Valley in San Juan, to 1600m in the Uco Valley and Pedernal, in the provinces of Mendoza and San Juan, respectively.
Thus, in addressing the terroirs of Argentina, it is best to put them in contrast by their altitude. Pedernal and the Uco Valley are very similar to each other. The reason for this is that at a similar altitude – with every 100 linear meters of ascent, the average temperature drops by almost 1ºC-, they have more in common with each other if they are compared with other twin latitudinal regions, but at very different heights, as with the East of Mendoza and Tulum in San Juan.
And if until recently there was only talk of the wines from Mendoza and San Juan, the reality in the glass compels us to break them up, not only into political units but into specific terroirs. It is in the contrast of details that the major differences lie. And to these details is where we now turn.
