Colli Orientali Friuli Wine Region

The “Friuli Colli Orientali” DOC (Friuli Venezia Giulia region, Norther Italy) an enclave of over 2,000 hectares of vineyards spread across twenty-four municipalities, has become a benchmark of Italian quality. It exports over 80,000 hectoliters of wine each year to markets as far-flung as the United States, Japan, Austria, and Germany.

In a historic villa in Corno di Rosazzo, home to the consortium’s headquarters, the story of those vines is being rewritten through scientific research, cutting-edge enology, and the dedicated efforts of a new generation of winemakers.

From the East to the “Sunny Slopes”

The tale begins far beyond the borders of modern-day Italy. Recent archaeological and genetic studies have overturned the long-held belief that the Celts who populated the Friulian plains came from the west. Instead, evidence now suggests an eastern migration, possibly from present-day Turkey, bringing with them basic knowledge of viticulture.

These early Celtic settlers began “appreciating and growing vines,” as scholars put it, sowing the first seeds on the sun-kissed slopes of the Colli Orientali. The Romans, ever the engineers of empire, cemented this practice. In 180 BCE, Titus Livius (Livy) recorded the founding of a Roman colony around Aquileia in his Ab Urbe Condita, laying the groundwork for organized agriculture in the region.

A century later, Julius Caesar himself left his mark. In 53 BCE, his legionaries founded Forum Iulii, later renamed Cividale del Friuli, where veteran soldiers turned peaceful settlers began cultivating the “eastern hills” with a vigor that would echo through the ages.

“The Roman legions were not just soldiers; they were also settlers and engineers. In many cases, they were the region’s first professional vintners,” notes Dr. Elisa Marini, a historian at the University of Udine.

Medieval Turbulence and the Persistence of Wine

The Middle Ages brought a patchwork of Lombard, Frankish, and later Patriarchal rule. With this came a series of political upheavals that threatened agricultural stability. Yet, even during those “dark centuries,” wine never disappeared from the table.

A document from 762 AD, the Pactum Donationis, states that “free farmers” had to deliver one hundred amphorae of wine each year to the nuns of the Salt di Povoletto monastery. By the end of the medieval period, wine had outgrown its clay containers and was being shipped in wooden barrels across Northern Europe—a testament to the quality of the product and the resilience of its producers.

In the early second millennium, the Patriarchs of Aquileia called upon Benedictine monks to revive the land, and the Abbey of Rosazzo became a beacon of agricultural renewal. The monks introduced systematic pruning, grafting, and a calendar of harvests that defined the region’s viticultural identity for centuries.

From Empires to the Italian Nation
The following centuries saw Friuli change hands as often as a winemaker changes barrels. The Serenissima Republic of Venice brought maritime trade routes, Napoleon’s armies introduced French viticultural terminology that still appears on DOC labels, and the Austro-Hungarian Empire brought Central European markets to the region.

In 1870, after a long period of foreign domination, Friuli was finally reunited with the Kingdom of Italy. Yet, despite the political flux, the vines thrived, nurtured by a cultural reverence for the land stretching back to Caesar’s legionaries.

A Modern Consortium with Ancient Roots

The Consorzio Tutela Vini “Friuli Colli Orientali e Ramandolo” (the “Consortium”) was founded in 1970, making it one of the earliest such bodies in Italy. The Consortium’s mission was to protect the DOC designation, promote quality, and ensure that the region’s winemaking heritage could survive the onslaught of industrial agriculture and global competition.

Today, the Consortium has about 200 members, three-quarters of whom are bottlers. Its 2,100 registered hectares produce over 80,000 hectoliters of DOC wine annually, at least 30% of which is exported.

“We are the custodians of a legacy that is both scientific and sentimental,” says Marco Bellini, the Consortium’s current president. “Our responsibility is to honor the centuries-old techniques while embracing the tools that modern enology offers.”

The Consortium’s headquarters, a majestic 18^(th)-century villa known as Villa Nachini-Cabassi, embodies that blend of past and present. Its stone walls and graceful columns have been restored to their original splendor and now serve as a tasting room, training center, and showcase for visitors from Lignano, Grado, and beyond.

The Terroir That Makes the Difference

The Colli Orientali’s reputation is based on a unique combination of soil, climate, and grape variety. The hills are primarily composed of calcareous marl, clay, and granite, which provides excellent drainage while retaining enough moisture to sustain the vines through the region’s temperate continental climate.

Warm, sunny days are followed by cool evenings—a diurnal shift that preserves the grapes’ acidity and aromatic compounds. The area’s proximity to the Adriatic Sea introduces maritime influences, such as gentle breezes that moderate the summer heat and prevent fungal diseases.

These conditions allow a spectacular array of native varieties to flourish:

• Malvasia, for example, is aromatic with notes of apricot and honey.
• Picolit is a rare, late-ripening grape that produces elegant, slightly oxidative wines.
• Pignolo is a robust, tannic red with a deep ruby color.
• Refosco dal Peduncolo Rosso is a peppery red with notes of dark fruit.
• Ribolla Gialla is a crisp, mineral white that is often sparkling.
• Schioppettino is a peppery, medium-bodied red.
• Tazzelenghe is a powerful, structured red with high acidity.
• Tocai Friulano, also called Friulano, is a fragrant white with an almond-hinted finish.
• Verduzzo Friulano is a sweet, late-harvest white.

According to the Consortium’s technical committee, these nine native grapes constitute the largest number of indigenous varieties protected under a single Denominazione di Origine Controllata (DOC) in Italy.

“The diversity of our native grapes is a living museum of the region’s agricultural history,” explains enologist Lucia Ferrara, who heads the consortium’s research lab. “Each variety tells a story about how our ancestors adapted to the land and climate.”

Tradition Meets Technology

Although the vines are ancient, modern methods are used for cultivation and vinification. Manual harvesting remains the norm, enabling workers to select only the ripest clusters and preserve the grapes’ integrity. In the cellar, state-of-the-art, temperature-controlled stainless steel tanks and oak barrels are used based on the style of each wine.

The Consortium has invested heavily in scientific research, partnering with the Department of Agricultural Sciences at the University of Udine. Recent trials have focused on:

– Sustainable canopy management to improve sunlight exposure while reducing the need for chemical sprays;
Precision viticulture using drone-based imaging to monitor vine health and soil moisture; and yeast biodiversity studies aimed at preserving native fermentative strains that impart unique aromatic profiles.
– yeast biodiversity studies aimed at preserving native fermentative strains that impart unique aromatic profiles.
These efforts have paid off. At the 2023 International Wine Challenge, Friuli Colli Orientali’s Ribolla Gialla “Villa Nachini” won a gold medal, and Picolit “Le Cantine di Arta” won a silver for its balance of acidity and residual sugar—a rare achievement for a late-harvest wine.

The generational shift from small-scale family farms to structured wineries is a recurring theme across the hills. Giovanni Dalla Valle, whose grandparents began cultivating vines in the 1920s, now runs Cantina Dalla Valle, a boutique winery that blends traditional foot-plowing with a micro-oxygenation system for its Refosco.

Indeed, the Consortium’s promotional activities have grown increasingly sophisticated. Since 2014, a small but dedicated team based in Villa Nachini-Cabassi has orchestrated tastings, roadshows, and digital campaigns across Europe, North America, and Asia. In 2022, a series of “Friuli Nights” events in Vienna, Berlin, and Munich attracted over 5,000 participants and boosted export sales by 12% the following year.

Challenges on the Horizon

Even as the region basks in newfound global attention, challenges loom. Climate change threatens the delicate balance of temperature and rainfall on which the Colli Orientali’s vines depend. The area has recorded an average temperature increase of 0.8°C in recent years, prompting concerns over earlier ripening and potential loss of acidity.

In response, the Consortium established a Climate-Adaptation Task Force to map heat-tolerant rootstocks and explore higher-altitude vineyard sites. Additionally, the group is lobbying the regional government for subsidies to support organic and biodynamic practices, which reduce carbon footprints and preserve soil health.

Another issue is preserving historic grape varieties like Tazzelenghe and Picolit, which are susceptible to disease and have low yields. Conservation programs funded by EU rural development grants are establishing germplasm banks to safeguard these genetic resources.

The story of Friuli Colli Orientali is, at its core, a story of continuity—of a people who have, for two thousand years, coaxed the land to produce wines that reflect both place and history. From the Celtic migrants who first recognized the hills’ potential, through Roman colonists, medieval monks, and modern entrepreneurs, the vines have endured.

With each harvest, the ancient tradition of Friuli’s “sunny slopes” finds new expression—one that respects the past while eagerly embracing the future.
