Wines from Uco Valley

A Key Winegrowing Region of Mendoza

Uco Valley, which is located in the southwestern part of Mendoza, Argentina, is basically a viticultural region. It would be apt if we call it as a key wine-growing region of Mendoza.

By taking just an hour’s drive from the city of Mendoza in the southern direction, we would reach this beautiful place.

Having located in a clearly defined valley along the Tunuyán River, this region is known for its remoteness.

But, I would say this remoteness is adding charm to this region. Let’s review about this top wine region of Mendoza here….

Geography and Topography of Mendoza

Several wine experts claim that the region’s specific merit is its placement at the higher altitudes at the foot of the Andes Mountains.

The valley’s sub-regions, La Consulta and Tunuyan are found to be sitting at the altitudes of 850 meters and 1100 meters respectively.

These are slightly higher than the other wine regions of Mendoza. The Uco Valley is found to be stretching from the Tupungato region on the northern side to the San Carlos on the southern side.

This way, the region is covering almost seventy kilometres in length and about twenty-two kilometres in width.

As such, the valley is found to be following the northerly course of the river as it flows from its source high up in the peaks of the Andes Mountains.

This topography is found to be playing a critical role in the region’s viticulture.

Climate and Soil Conditions s in Uco Valley

The Uco Valley, which is located at the latitudes of 33°S, has its vineyards at the elevated altitudes.

As such, these vineyard sites are found to be benefiting from the higher daytime temperatures, which drop down to cooler temperatures at nights.

These climatic conditions enable the wine grapes of the region to develop balanced sugars and acidity when at the same time being able to achieve phenolic ripeness.

On the other, these dry continental types of climate are found to be bringing only a little rain to the region’s vineyards thus making wider irrigation techniques important.

The soils of the Uco Valley region are found to be alluvial throughout and are fairly uniform. In most of the parts, we can see a clay and rock base with the stony and sandy surface.

Thus, these soils are found to be free draining and are excellent for high-quality viticultural practices.

It’s because these types of soils would stress the vines thereby leading to the decreased vigor, as well as lower yields.

Thus, what we achieve is a higher concentration of flavours in the wine grapes.

The amazing sceneries along with the state-of-the-art winemaking techniques have made the Uco Valley as equivalent to the Napa Valley of California.

At present, a total of 24,000 hectares of land is put under vineyard cultivation. It’s to be mentioned that the valley is the source of several greatest red wines of Argentina.

Although this region is considered to be the part of Mendoza, the valley has its own identity on several aspects.

Firstly, this is a quite distinctive wine region. Secondly, this is home to many of Argentina’s top wine producers.

All these factors together have given the Uco Valley a strong place on the wine map of the world.

The iconic grape variety of Argentina, Malbec, is found to be shining well in the Uco Valley with a distinctive floral aroma.

The finest white wines of Mendoza made using Chardonnay and Torrontés are also coming from Uco Valley.
