The Uco Valley has become the centre of interest for high-quality wines in Mendoza. Although there are old vineyards planted over 70 years ago, the valley has only come to prominence in the last ten years or so. Before this, it was the vineyards close to the city of Mendoza – Vistalba, Compuertas, Agrelo and Perdriel – that were the most reputed.

The Uco Valley is cooler than the vineyards near Mendoza City because it is further south, closer to the Andes and has some vineyards at higher altitudes, up to 1,500 metres.
Also the Rio Las Tunas and the Rio Tunuyan have brought limestone deposits to those areas bordering the rivers, especially Gualtallary, Paraje Altamira and La Consulta.

Wines grown on limestone soils are generally low vigour, so produce concentrated wines with firm, long and linear palates with a character often described as more mineral than fruity.

So far, few of the subregions of the Uco Valley (Gualtallary, Chacayes, Vista Flores, La Consulta) have appeared on the labels because some have been trademarked by existing wine producers! One 'workaround' found for Altamira, which has also been trademarked, was to call it 'Paraje Altamira' or 'Altamira Region.'

The cooler climate means some of the country's best white wines are being grown here, perhaps especially Catena's chardonnays from Gualtallary. Mendel make a wonderful semillon from 70-year-old vines in Altamira.

Inevitably it has also become known for the quality of its malbecs. The cooler climate here produces some lovely floral and violet-scented malbecs. Also in Altamira and La Consulta the limestone soils give the relatively low-tannin malbec more structure and length. Susana Balbo's La Delfina and the Zaha and Teho wines are lovely examples of this.
