Deep inside the Italian Alps, at nearly 2,000 metres above sea level, selected wines of La Crotta di Vegneron undergo a unique ageing journey inside the historic Costa del Pino magnetite mines in Cogne. Created by this cooperative of alpine winegrowers from the Valle d’Aosta (Aosta Valley), the project transforms a former mining site into an extraordinary underground cellar where time, temperature, and the mountain itself shape the evolution of the wines. It is a story that brings together heroic viticulture, local heritage, and the deep connection between the people of the Alps and the land they cultivate.

A Cooperative Born to Protect the Mountain

In the Valle d’Aosta, where vineyards climb steep Alpine slopes and farming has always required courage, patience, and determination, La Crotta di Vegneron represents far more than a winery. It is the story of a community that came together to protect a landscape, preserve a tradition, and give new life to mountain viticulture.

Founded in 1980 by a group of local grape growers, the cooperative was created at a time when many hillside vineyards across the valley had been abandoned. Without vines anchoring the slopes, the land became increasingly vulnerable to erosion and hydrogeological instability. The growers understood that restoring the vineyards meant safeguarding not only wine production but also the fragile relationship between people and their mountain environment.

What began as a collective effort among approximately 135 members has evolved into a cooperative of 39 winegrowing families, united by a commitment to greater quality, sustainability, and the preservation of the region’s viticultural heritage. Today, they cultivate some of Italy’s most demanding vineyards, producing around 200,000 bottles each year from slopes where every vine reflects the character and resilience of the Alps.

A Mountain Terroir Shaped by Extremes

The wines of La Crotta di Vegneron are born from one of Italy’s most distinctive wine-growing environments. The cooperative’s vineyards extend for nearly 20 kilometres across the central Valle d’Aosta, from Saint-Vincent to the border between Nus and Quart, following the contours of a valley shaped by altitude and mountains.

Although surrounded by some of Europe’s highest peaks, this area has a surprisingly dry climate. Annual rainfall is often below 500 mm, with particularly limited precipitation during the summer growing season. Under these conditions, traditional manual irrigation remains an essential part of vineyard management.

The vineyards are planted on soils of glacial moraine origin, composed largely of coarse sand with very little clay. Combined with constant mountain winds and significant differences between warm days and cool nights, these conditions encourage slow and balanced grape maturation while preserving freshness, acidity, and aromatic complexity.

Nearly 90% of the vineyards face south, maximizing sunlight exposure, while elevations range from 450 to 800 metres above sea level. The steep slopes, often with gradients between 20% and 35%, make mechanization nearly impossible, placing La Crotta di Vegneron among the finest examples of heroic viticulture.

Hillside, Sun, Stone and Wind

At La Crotta di Vegneron, Hillside, Sun, Stone and Wind reflects the natural forces that shape every vineyard and every bottle produced by the cooperative.

The hillsides provide exceptional drainage and exposure, allowing vines to grow in a challenging Alpine environment. The intense sunlight at high altitude encourages slow ripening, helping grapes develop both concentration and freshness. The stone-rich soils retain heat during the day and release it gradually, contributing to the mineral character of the wines. Meanwhile, the mountain winds reduce humidity and disease pressure, allowing growers to work with a more balanced approach to vineyard management.

Rather than imposing a uniform style, La Crotta di Vegneron embraces the individuality of each vineyard. Differences in soil, altitude, and exposure are preserved, allowing the landscape itself to become part of the identity of every wine.

Wines That Tell the Story of the Mountains

The wines of La Crotta di Vegneron express the unique identity of the Valle d’Aosta through native grape varieties, alpine conditions, and generations of vineyard knowledge. The cooperative works with some of the region’s most distinctive indigenous grapes, including Petit Rouge, Fumin, Cornalin, Vien de Nus, and Prié Blanc, transforming them into wines that reflect the character of this mountain landscape.

The vineyards extend across the historic DOC production areas of Chambave and Nus, where steep slopes, high-altitude vineyards, and diverse microclimates contribute to wines known for their freshness, elegance, and aromatic intensity. Each variety reveals a different expression of the Valle d’Aosta terroir, from the structure and spice of the region’s red grapes to the floral and mineral qualities of its rare white varieties.

Rather than pursuing a standardized style, La Crotta di Vegneron focuses on preserving the identity of each vineyard and grape variety, allowing the nuances of the Alpine environment to emerge in every vintage. As a founding member of the Consortium for the Protection of the Valle d’Aosta DOC appellation, the cooperative plays an important role in safeguarding the authenticity, quality, and heritage of the region’s wines.

Where the Mountain Becomes Part of the Wine

The most extraordinary expression of La Crotta di Vegneron’s connection with the Alps can be found deep inside the historic Costa del Pino magnetite mines in Cogne.

At nearly 2,000 metres above sea level, selected bottles are aged in an underground environment unlike any traditional cellar. Visiting this remarkable space, it becomes clear that the mine is not simply a place where wine is stored—it is a continuation of the mountain landscape that surrounds the vineyards.

Inside the former mining galleries, temperatures remain constant at around 7°C, with humidity levels close to 90% throughout the year. Protected from light and seasonal fluctuations, the wines evolve slowly and naturally, allowing aromas, structure, and texture to develop with extraordinary patience while preserving freshness and energy.

The stable underground conditions create an ageing journey unlike that of a conventional cellar. Here, time moves differently. The mountain provides an environment where the wines can mature gradually, adding complexity while maintaining the vibrant acidity that defines Alpine wines.

During our visit, we tasted two remarkable examples of this project: Valle d’Aosta DOC Chambave Muscat 2020 and Valle d’Aosta DOC Fumin 2017. Both demonstrated the elegance of slow ageing, showing depth and complexity while retaining the vitality of their mountain origin.

The Costa del Pino mines are themselves an important part of the history of the Aosta Valley. Among the highest magnetite mines in Europe, the site has roots dating back to 1432, when the first documented extraction of magnetite took place. After centuries of activity and industrial development during the twentieth century, the mines closed permanently in 1979.

Today, more than 100 kilometres of tunnels extend through the heart of the mountain. Visitors can explore part of this underground world by vintage mining train and guided walks, while La Crotta di Vegneron’s bottles quietly rest in what was once the mine’s powder magazine—a space transformed from a place of extraction into a sanctuary for wine.

The connection between wine, art, and local heritage continues through the labels of this collection, inspired by the work of Barbara Tutino, an artist from Cogne whose painting formed part of Le travail de l’homme, an exhibition dedicated to miners and workers. Her work celebrates resilience, craftsmanship, and the enduring relationship between people and the mountains.

By ageing wines beneath the same Alps that shape its vineyards, La Crotta di Vegneron creates a rare dialogue between nature, history, and human ingenuity. Here, the mountain is not simply the backdrop to the wine—it becomes an essential part of its journey from grape to glass.
