Uco Valley

The Uco Valley unfolds at altitude, where the air is thin, the light is crystalline, and the Andes rise as an impossibly dramatic backdrop to row upon row of grapevines. Situated about 100 kilometres south of Mendoza city, this is where Argentine winemaking has found its most exciting new frontier — a high-altitude cool-climate zone producing Malbecs and Chardonnays of extraordinary depth and complexity. Driving the valley's back roads past adobe estancias and cutting-edge winery architecture, you understand why wine lovers travel from across the world to spend time here.

History of Uco Valley

The Uco Valley's wine history stretches back to Spanish colonial times, when Jesuit missionaries planted the first vines in the region during the 17th century. For much of its early history, the valley supplied table grapes and bulk wine rather than fine wines — its remoteness and altitude presented logistical challenges that limited investment. The irrigation systems developed over centuries, drawing meltwater from the Andes via an elaborate network of acequia canals, laid the agricultural foundation the modern wine industry now depends on.

The transformation into a premium wine region began in earnest in the 1990s and accelerated through the 2000s, as international investors and Argentina's own wine pioneers recognised that the valley's extreme diurnal temperature variation — scorching days and cold nights — was ideal for preserving the aromatic complexity that marks fine wine. Today the valley is home to more than 20 wineries ranging from intimate boutique operations to grand estates designed by celebrated architects, and its wines command international attention and prices to match.

What to See and Do

A visit to the Uco Valley is primarily a winery experience, but the valley itself — with its snow-capped mountain backdrop, olive groves, and fruit orchards interspersed with vineyards — is strikingly beautiful. Most visitors plan itineraries around two or three winery visits per day, with tastings, tours, and often a long lunch at one of the valley's acclaimed winery restaurants. Bodega Salentein, with its Dutch-influenced estate, and Zuccardi Valle de Uco, regularly ranked among the world's best restaurants and wineries, are standouts.

Beyond wine, the valley offers horseback riding through the vineyards, cycling between estates, and hiking and climbing routes into the Andes foothills. The town of Tunuyán serves as the valley's main service centre, and several luxury vineyard lodges offer multi-day immersion experiences where you wake surrounded by vines and retire each evening to fine wine and starlit skies.

The Wines

Malbec is the grape most associated with Mendoza and dominates the Uco Valley, but here it expresses itself differently — with greater elegance, higher acidity, and more restrained fruit than the plush, warmer-valley styles. The valley's sub-zones — Altamira, Gualtallary, Los Arboles, and Vista Flores — each produce wines with distinctive character. Gualtallary, at the highest elevations, produces particularly mineral, structured Malbecs and Chardonnays prized by collectors worldwide.

Cabernet Franc, Chardonnay, and Cabernet Sauvignon also thrive here, and several producers are experimenting with Italian and Iberian varieties. Blends using traditional Bordeaux varieties alongside Malbec represent some of the valley's most ambitious wines. Most winery tasting rooms are open by appointment and offer flights of three to six wines, sometimes accompanied by regional food pairings.

Local Insights

What locals know that guidebooks do not always tell you:

• Hiring a private guide or driver is strongly recommended — the valley has no public transport and wineries are spread across vast distances. Some of the best producers are on unpaved roads.
• Book the Zuccardi winery restaurant weeks in advance — it regularly appears on the World's 50 Best Restaurants list and tables disappear fast.
• Altamira sub-zone is considered by many producers to be the valley's finest terroir for Malbec. Ask specifically for Altamira wines when tasting.
• Late afternoon light turns the vineyard rows and Andean peaks golden — plan to be at a winery with outdoor seating at sunset if you can.
• The valley sits at 900–1,500 metres altitude. Drink plenty of water between tastings; the thin dry air accelerates the effects of alcohol and dehydration.
