The Transformation of Uco Valley’s Wines

During harvest time in Argentina’s Uco Valley, it’s all about deep purple—the color, not the “Smoke on the Water” rockers. Dark purple-skinned grapes pack the nearly 70,000 acres of vineyards that stretch from Tupungato south to San Carlos, while shades of violet color the lips, teeth and fingernails of the region’s winemakers.

Sebastián Zuccardi is a perfect example. During March, at his family’s two-year-old, solid-stone winery in the Paraje Altamira section of San Carlos, Zuccardi looked as though he’d just munched on a thousand Malbec grapes. His mouth and hands were stained violet, which is just how this progressive winemaker likes it when it’s time to pick.

“I’ve been tasting grapes all day,” says Zuccardi. “This vintage [2018] is going to be great: great balance; great alcohol levels.

“Winemaking in the Uco Valley is now one part science and one part skin. If you don’t know your soils and you don’t regularly taste your grapes, you won’t be able to make the type of Malbecs and other wines that Uco is becoming known for.”

The style to which Zuccardi refers is fresh, racy and clean, sometimes with no oak and definitely without a preponderance of overripe fruit flavors and new-wood character. This genre of wine, which has grown in popularity in many parts of the world, marks a wholesale departure from what Mendoza has produced for much of the last two decades.

Argentina’s vinous notoriety surged at the beginning of the 21st century, when size and power were what mattered most. The country’s Malbecs and other red wines earned a reputation for being beefy, often raisiny, loaded with oak and commonly put through acidity correction for better balance.

That type of wine is no longer in vogue.

“Freedom without fear is our new theme,” says Marcos Fernández, head winemaker at Doña Paula, with palpable pride. As he stood in the winery’s rock-filled vineyard in the Gualtallary district of Tupungato, Fernández said that he and his peers are, in general, harvesting significantly earlier than in the past to corral and preserve natural acidity.

“Relying on vineyards with large alluvial deposits from the omnipresent Andes is the key to producing fresher, more mineral-rich wines,” says Fernández. “We are a younger generation of winemakers, and we are trying to change the perception of quality. We used to believe that more of everything was better—more ripeness, more oak, more alcohol. But along the way, we’ve learned that if you wait too long to pick, you lose that sense of place.”

“The legendary French enologist Émile Peynaud famously said that in Bordeaux, all wines above 13.5% alcohol are similar,” says Roberto de la Mota, one of Mendoza’s most revered winemakers. “For us, the same rule can be applied at 15%.”

A partner in Mendel Wines, de la Mota makes a superb Uco Valley Malbec called Finca Remota, named for the vineyard where it’s grown. The plot was planted in Altamira during the 1950s, back when the Uco Valley was legitimately remote. Now that the Uco Valley has come of age, he and partner Anabelle Sielecki hope to construct a small winery in the Paraje Altamira district near to Zuccardi’s Bodega Piedra Infinita.

“Calcareous soils at nearly [3,600 feet] of elevation? That’s unique to Altamira, and it makes all the difference,” he says.

Uco Then and Now

Known locally as the Valle de Uco despite not being a true valley, the region stretches roughly 45 miles from north to south, and is flanked to the west by the massive Andes. To the east, however, there’s nothing but flatlands and pampas until Buenos Aires and the Atlantic Ocean, around 700 miles away. The best vineyards, those planted over the past two decades and others with even older and deeper roots, push up against the Andes. They benefit from high elevations and cold nights.

As for terroir, the Uco Valley is pure high desert. It receives plentiful water from Andean snowmelt, however, spawning a plethora of flora, while millions of years’ worth of alluvial deposits fill the subsoils from Gualtallary in Tupungato through Los Chacayes in central Tunuyán to aforementioned Paraje Altamira in San Carlos.

Other Uco microzones that have earned their stripes include San Pablo, located in the highest reaches of southern Tupungato; Vista Flores and Los Arboles in Tunuyán; and La Consulta in San Carlos.

Ten years ago, I spent a week touring the Uco Valley. After that trip, I wrote one of the first articles in the mainstream wine press that focused on this rural region, rather than the more established and inhabited winegrowing areas closer to the city of Mendoza.

The Uco Valley was still untapped then, but it was loaded with can-do spirit and the potential to make fresher, more vivacious wines from varieties beyond Malbec, like Cabernet Sauvignon, Cabernet Franc, Chardonnay and Pinot Noir.

Back in 2008, the main brick-and-mortar projects in the Uco Valley included a group of seven Bordeaux families who made proprietary wines and a collective bottling called Clos de los Siete, which continues to impress for its quality-to-price ratio.

Other wineries that fueled growth include Bodega Catena Zapata, a leader in high-elevation plantings in Tupungato and a driving force for all of Argentina;­ Altos Las Hormigas, co-founded by the Italian winemaker Alberto Antonini; and Achaval-Ferrer, a joint-venture between two Argentines and two Italians, including winemaker Roberto Cipresso.

Another that set the pace was a Chacayes-based winery established by Bordelais brothers François and Pierre Lurton. It’s now called Bodega Piedra Negra and run solely by François.

Today, there are even more wineries and vineyards that dot the Uco Valley, with new boutique-size bodegas under construction from the likes of Catena Zapata and Trapiche. Of the 22 wines that Matías Riccitelli currently bottles at his Luján de Cuyo winery, many rely on Uco Valley fruit. In mid-March, Riccitelli was already crushing Malbec from Gualtallary. In the past, he says, the same fruit would have arrived a month later, at a higher brix and therefore less potential for freshness and tension.

“We are working with much lower yields than ever before, so the vines are maturing faster,” says Riccitelli. “The acidity is natural, not added. The combination of sugars, pH levels and acidity can be perfect.”

As the stereo filled his funky bodega with Fela Kuti, Riccitelli explained what he and Gabriela Lombardi, his wife and assistant winemaker, love about the Uco Valley.

“In the early days, meaning 15 to 20 years ago, the creativity came from outside,” he says. “You had Michel Rolland and his Bordeaux friends at Clos de los Siete, Paul Hobbs [from California] at Cobos, and Hans Vinding-Diers [a Dane] with Noemia down in Patagonia. But now the influence is coming more from within. People like us, Seba Zuccardi and the Michelini brothers….we all have an understanding of the terroir and what kinds of wines we want to make.”

“The pendulum is swinging in the direction of wines with nerve and intensity. For that, the Uco Valley is perfect,” says Matías Michelini, one of four Mendoza-born brothers that make numerous wines from vineyards scattered throughout the region. He started his Passionate Wine label in 2009 with just two wines; now, he makes 28. His brothers, Juan Pablo, Gerardo and Gabriel, produce a cross section of new-age Uco Valley wines, including a joint-effort Malbec called SuperUco.

So what’s the current takeaway? For Malbecs and other wines with bright fruit and balance, the Uco Valley is where to look.

From Zuccardi’s Polígonos single-­vineyard wines, Riccitelli’s complex Tupungato Chardonnay and Laura Catena’s fledgling Domaine Nico Pinot Noir from the highest reaches of Gualtallary that showcases superb elegance, it’s clear that Uco Valley’s 20-year rise to glory is still going strong.
