The Mountaineer's Hand & the Calingasta Stone

The story of Cara Sur begins with friendship and a shared obsession with the impossible. In 2011, Sebastián Zuccardi — already one of Argentina's most celebrated winemakers, architect of the 100-point Familia Zuccardi empire — and his wife Marcela Manini teamed up with Pancho Burgallo and Nuria Año Gargiulo, a couple of avid mountaineers who live in Barreal, a tiny village in the Calingasta Valley of San Juan, north of Mendoza. The four were united by a single conviction: that the ancestral vines of the Calingasta Valley — gnarled, old, and largely forgotten by the commercial wine industry — deserved to be revived, respected, and bottled as the unique expressions of terroir that they are.

The name Cara Sur — South Face — is not a marketing abstraction. It refers to the more challenging approach to Cerro Mercedario, one of Argentina's tallest peaks at 6,720 metres, which dominates the horizon from Pancho and Nuria's hometown of Barreal. Pancho, a committed mountaineer, once attempted to tackle the legendary south face of this massif in the middle of winter — a feat of audacity that mirrors the project's own spirit. The south face is the harder route, the one fewer climbers choose, the one that demands more patience, more skill, and more respect for the mountain. It is, in other words, the perfect metaphor for what Cara Sur attempts in wine: the harder path, the quieter revolution, the refusal to take the easy route of international varieties and new oak.

Sebastián and Marcela regularly make the trip north from Mendoza to work alongside Pancho and Nuria in Barreal. The quartet operates not as employer and employees but as genuine partners — four people sharing a single vision, divided between two homes, united by a single cellar. For Sebastián, Cara Sur is a passion project — a side venture that allows him to step outside the scale of Santa Julia and Familia Zuccardi and return to the intimacy of small-batch, hands-on winemaking. For Pancho and Nuria, it is a way of life — a project rooted in their home, their mountain, and their community. Together, they have created something that neither couple could have achieved alone: a wine that tastes of the Calingasta Valley's stones, its rivers, and its vertiginous silence.

The cellar philosophy of Cara Sur is shaped by Sebastián Zuccardi's conviction that the best wine is the one that interferes least — and by the mountaineering spirit of Pancho and Nuria, who understand that the hardest route is often the most rewarding. The wines are made in a tiny winery next to Pancho and Nuria's home — not a gleaming cathedral of technology but a working cellar where four people handle every aspect of production by hand. The guiding principles are clear and unbending: freshness, salinity, rusticity, texture. The team is against colour, against extraction, and against wood flavours. The vineyard itself is the palette; the winemaker's job is to translate, not to transform.

The wines are fermented with ambient indigenous yeasts — the wild microorganisms that live on the grape skins and in the cellar air. There is usually some skin contact, and a degree of flor develops on both whites and reds — the veil of yeast that protects the wine from oxidation and lends a subtle, nutty, saline complexity. Malolactic fermentation happens naturally and invariably. The wines are never filtered and never fined — preserving the raw, living texture of the fruit. Small quantities of sulfites are used, usually after fermentation finishes or just before bottling, but always with restraint. The concrete eggs — shaped vessels that create a natural convection current, keeping the lees in suspension — provide gentle micro-oxygenation and textural depth without the flavour influence of oak. And the co-fermentation of mixed varieties ensures that the lighter grapes always ameliorate the darker ones, creating a harmony that no single variety could achieve alone.

The result is a style that Sebastián describes as rustic — deliberately unpolished, deliberately unaromatic in the conventional sense. These are not wines that shout; they are wines that whisper of stone, sun, and silence. The rough edges are deliberate. The wines are moreish and digestible — wines made for food, for conversation, for the long table. You can easily imagine them beside a mountain stew, a grilled river trout, or a simple plate of cheese and bread at altitude. The single-parcel wines — produced in quantities of just over 1,000 bottles each — are the most refined expressions of this philosophy, capturing the sweet spots in the vineyard where the grapes and terroir speak with the clearest voice.

Cara Sur is not merely a winery; it is a proof that two couples — one from the summit of Argentine wine, one from the foot of the Andes — can revive ancestral vines in a forgotten valley and produce wines that belong on the world's finest tables. In an era when Argentine wine is dominated by the international varieties and polished oak profiles of the Uco Valley and Luján de Cuyo, Cara Sur has demonstrated that the harder path is the more rewarding one — that the same Calingasta stones that have been dismissed by the commercial industry can produce Bonarda, Criolla Chica and Moscatel of extraordinary depth, that the same Parral canopy that looks archaic to modern viticulturists is actually a genius adaptation to extreme UV, and that a tiny cellar next to a mountaineer's home can produce wines that rival the output of far larger, far more funded estates.

The legacy of Cara Sur is the legacy of the south-facing hand in viticulture. The 2011 founding is not a distant memory but a living covenant — a reminder that the best way to honour the past is to farm the old vines as they have always been farmed, without chemicals, without hard pruning, without the homogenising pressure of the market. The Parral system is not a nostalgic relic but a functional masterpiece — a ceiling of leaves that protects fruit from the sun and creates a microclimate of freshness in a valley that would otherwise produce only raisins. The concrete eggs are not a trend but a logical choice — a neutral vessel that provides texture without masking the vineyard's voice. And the co-fermentation of mixed varieties is not a gimmick but a heritage method — a way of producing wine that is greater than the sum of its parts, just as the four people who make it are greater together than they are apart.

The future of the project is tied to the future of Argentina's ancestral wine movement — to the growing global recognition that the country's viticultural heritage lies not only in Malbec but in the Criollas, Cerezas, Moscatels and Bonardas that have survived for generations in valleys like Calingasta. As Barreal Tinto continues to earn 92-point scores from the world's most demanding critics, as Pérgolas Criollas introduces a new generation to the freshness of high-altitude Criolla, as the single-parcel wines prove that 80-year-old País can produce wines of world-class elegance, and as Sebastián, Marcela, Pancho and Nuria continue their quiet revolution from a tiny cellar beneath Cerro Mercedario, Cara Sur remains what it has always intended to be: a mountaineering expedition into the soul of Argentine wine — structured, rustic, and deeply tied to the stony soils, glacial rivers, and vertiginous silence of the Calingasta Valley. The story of Cara Sur is the story of four people who looked at the south face of the mountain and chose to climb it — and who proved that the best bottle from Argentina is sometimes the one that tastes least like wine technology, and most like the wild, co-planted, Parral-shaded earth of San Juan.
