We Don't Follow Formulas

The story of Castello di Stefanago begins over a thousand years ago, when an 11th-century castle was built on the hills of the Oltrepò Pavese — a fortress that would watch over the vineyards, forests, and meadows of this extraordinary landscape for a millennium. The castle still stands today, its stone walls and towers a testament to the deep history of this corner of Lombardy, where viticulture has been practiced since Roman times. The Baruffaldi family has owned the property for generations, passing down not only land and vines but a profound respect for the terroir and a commitment to preserving the delicate balance between agriculture and nature.

The Oltrepò Pavese is one of Lombardy's most important wine regions, historically known for its sparkling wines and distinctive red varieties. But it is also a region that has been overshadowed by the more famous zones of Piedmont and Franciacorta, its potential underappreciated by the broader wine world. The Baruffaldi brothers — Antonio and Giacomo — saw this not as a disadvantage but as a responsibility: to prove that the Oltrepò Pavese, with its clay-limestone soils, significant elevation, and wide diurnal temperature shifts, can produce wines of world-class quality when farmed with patience and respect.

The estate is not merely a collection of vineyards; it is a 135-hectare ecosystem — a living landscape where 20 hectares of vines coexist with forests, meadows, orchards, and arable land. This diversity is not accidental; it is deliberate. The Baruffaldis believe that biodiversity is the foundation of healthy viticulture, that the woods and meadows are not separate from the vineyards but integral to their health. Over 80 bee families thrive on the estate, producing wildflower honey and pollinating the flora. Sheep graze between the vines. Cover crops and green manure maintain soil vitality. This is polycultural agriculture as it was practiced for centuries before monoculture took hold — a return to wisdom rather than a rejection of progress.

The name "Stefanago" carries the weight of medieval history, of feudal lords and agricultural traditions that stretch back to the Dark Ages. But the Baruffaldi brothers have not allowed history to imprison them; they have used it as a foundation for innovation. The castle's cellars, with their naturally stable temperature and humidity, provide the ideal environment for minimal-intervention winemaking. The estate hosts "Natural Wines Oltrepo & Friends" — an annual event that brings together natural, artisanal, and biodynamic producers from the Oltrepò and beyond. For Antonio and Giacomo, the castle is not a museum; it is a living, working farm where the past informs the future and where every bottle carries a thousand years of terroir.

At Castello di Stefanago, the cellar philosophy is one of absolute minimal intervention — a natural extension of the organic, regenerative farming practiced in the vineyard. The Baruffaldi brothers do not follow fixed recipes; they listen to each vintage, understanding the rhythms of nature and allowing each harvest to express itself fully. Time is a key factor, especially in the hand-harvesting of grapes. Each year, they develop a dedicated plan to make the most of what nature provides. This collaboration with nature, grounded in observation and timing, results in wines that change subtly from year to year — and this very variability is the essence of their winemaking. The wines are not subjected to invasive fining or filtration. Some bottles, once opened, may show slight signs of refermentation — a natural phenomenon linked to their artisanal approach and a reflection of the wine's authenticity.

The techniques are demanding, intuitive, and deeply rooted in both tradition and innovation:

Harvest & Selection: All grapes are meticulously hand-harvested from the estate's 20 hectares of organically farmed vineyards. Antonio and Giacomo monitor each vineyard daily in the weeks leading up to harvest, tasting berries and waiting for the moment when phenolic ripeness, sugar concentration, and acid balance align. The harvest is selective and careful — only the finest bunches are chosen, and they are transported quickly to the historic castle cellars to preserve freshness. The timing is different every year, adapted to the unique conditions of each vintage — a flexibility that is only possible when the vigneron is present, attentive, and unbound by industrial schedules.

Méthode Ancestrale Sparkling Wines — The Estate's Signature: Castello di Stefanago is particularly celebrated for its sparkling wines made using the méthode ancestrale — pétillant naturel — a technique that predates the Champagne method by centuries. The wines are bottled during fermentation, trapping the natural carbon dioxide produced by the indigenous yeasts. They spend years on the lees with native yeasts before disgorgement, developing extraordinary depth, complexity, and autolytic character. The result is a deep, expressive wine where vintage and time harmonize naturally — often rustic, vibrant, and cloudy, with a natural effervescence that is unlike anything produced by industrial methods. The "100" Ancestrale Bianco is a benchmark — 100% estate-grown, spontaneously fermented, aged on lees for years, disgorged by hand. It is a wine of extraordinary vitality: fine persistent mousse, biscuity complexity, citrus, and a distinct mineral backbone that speaks of the limestone soils. The "24 Ancestrale" — a blend of 60% Chardonnay and 40% Riesling Renano — is equally remarkable, combining the body and richness of Chardonnay with the aromatic intensity and acidity of Riesling. These are not merely sparkling wines; they are liquid expressions of time, place, and patience.

"Orangiosauro" — The Long-Macerated White: The "Orangiosauro" is one of the estate's most distinctive and celebrated wines — an orange wine that showcases the depth and complexity achievable with extended skin contact on white grapes. Made from a blend of Chardonnay and Cortese, the grapes are macerated on their skins for 48 days, extracting color, tannins, and aromatic compounds that transform the wine from a simple white into something extraordinary. The result is a bright copper-golden wine with a slightly oxidized but vibrant character: tangerine zest, chamomile, wildflower honey, and a slight funk that is utterly compelling. It is textured, nuanced, and distinctive — proof that orange wine, when made with patience and respect, can achieve a complexity and depth that rivals the world's finest reds. This is not a wine for the faint of heart; it is a wine for the curious, the adventurous, the lovers of wines that challenge and surprise.

Riesling Renano — The Elegant White: The Riesling Renano at Castello di Stefanago is one of the estate's strongest reputations — a wine known for its elegance, minerality, and ageing potential. The grapes are hand-harvested from the estate's highest vineyards, where the cool nights and limestone soils create ideal conditions for this demanding variety. Fermentation is spontaneous, ageing takes place in a combination of stainless steel and old wood, and the wine is bottled without fining or filtration. The result is a wine of extraordinary purity and precision: lime, petrol, white flowers, and a distinct mineral backbone that speaks of the terroir. It is a wine that rewards patience — years of cellaring will reveal more honey, wax, and kerosene complexity — and that proves the Oltrepò Pavese can produce Riesling of world-class quality.

"Campo Castagna" Pinot Nero — The Alpine Red: "Campo Castagna" is Castello di Stefanago's purest expression of Pinot Nero — grown at altitude on limestone-rich soils, fermented with native yeasts, and aged in neutral oak. The result is a delicate yet deep red, with notes of red cherry, crushed rose, forest herbs, and spice. It is elegant, wild, and whisperingly complex — Pinot Nero with a distinctly Lombard identity, shaped by the elevation, the wind, and the clay-limestone terroir of the Oltrepò Pavese. It is proof that this variety, often considered finicky and difficult, can achieve greatness when farmed with patience and respect in the right terroir.

Red Wines — Croatina, Barbera, Uva Rara: The estate produces a range of red wines from local varieties — Croatina (Bonarda), Barbera, and Uva Rara — each handled with the same minimal-intervention approach. The Croatina is deep, rustic, and fruit-driven, with notes of wild berry, plum, and a distinct earthy undertone. The Barbera is vibrant and acidic, with cherry, spice, and a freshness that makes it immediately drinkable. The Uva Rara contributes elegance and finesse, with delicate aromatics and a silky texture. All are fermented spontaneously, aged in neutral vessels, and bottled without fining or filtration — honest, traditional, and deeply expressive of the Oltrepò Pavese terroir.

The "Stüvenagh" Collection — Young, Bold & Eccentric: The "Stüvenagh" collection is Castello di Stefanago's line of young, bold, and eccentric wines — a stylistic hallmark of a way of understanding wine and nature as a whole. It includes pét-nat, PIWI (fungus-resistant) varieties, ancestral method wines, and orange wines — all produced with the same minimal-intervention philosophy but expressed in a more immediate, playful register. These are wines for the natural wine crowd: cloudy, funky, alive, and utterly distinctive. They represent the frontier of the estate's exploration, pushing boundaries while maintaining the integrity and authenticity that define the Baruffaldi brothers' approach.

Ageing & Bottling: The estate's approach to ageing is deliberately varied and patient. Stainless steel tanks preserve freshness and aromatic purity, particularly for the white wines and the younger, more immediate expressions. Concrete tanks provide gentle micro-oxygenation and a subtle mineral imprint that adds complexity without wood flavors. Old wood — barrels of various sizes and origins — allows for slow, gentle evolution that develops texture and depth without adding dominant toast or vanilla. The sparkling wines spend years on the lees in bottle, developing autolytic complexity through patience alone. There is no new oak dominance, no technological shortcuts — only the gift of time and the unique character of each vessel. The wines are bottled without fining or filtration, preserving their natural texture, flavor layers, and living energy. Minimal to no sulfur is added. The result is wines that are pure, unadulterated reflections of their origin — alive, evolving, and unmistakably honest.
