Three Sisters, One Hectare
Castello Conti is a tiny, family-run estate rooted in the heart of Boca, in the Alto Piemonte region of northern Piedmont — one of Italy's most historic and noble Nebbiolo-based wine districts. Founded in 1963 by Ermanno Conti, the estate is now led by his three daughters — Elena, Anna, and Paola — who represent the second generation to tend the family's vineyards. With just 2.5 hectares of vines divided into seven hillside parcels on volcanic porphyry soils, the Conti family rigorously applies certified organic standards to their farming, performs a manual harvest, and continues the same philosophy in the cellar: indigenous yeasts, little to no sulfur, and a deep respect for the traditional field blends that once defined Alto Piemonte viticulture. The result is a portfolio of wines that are precise, terroir-driven, and expressive of Boca's unique volcanic character — wines that resonate with connoisseurs and collectors who understand that greatness does not require scale.
A Father's Legacy, Three Daughters' Devotion
The story of Castello Conti begins in 1963, when Ermanno Conti established the estate in Maggiora, a small village in the Boca DOC of Alto Piemonte — a region renowned for its noble Nebbiolo-based wines and a viticultural history that stretches back centuries. Ermanno planted the family's first hectare of vines on two hillside parcels, choosing varieties that were traditional to the area: Nebbiolo (locally known as Spanna), Vespolina, Croatina (Bonarda), Uva Rara, and Barbera. These were not commercial decisions; they were acts of faith in a terroir that had produced some of Italy's most elegant and long-lived wines long before Barolo became famous.
For decades, Ermanno tended these vines with the patience and rigor that only a small-scale farmer can afford. He worked the land by hand, harvested manually, and made wine in the traditional manner — spontaneous fermentation, extended maceration, ageing in large old casks. He was not following trends; he was following the land. And when the time came to pass the torch, it was not to a son but to three daughters — Elena, Anna, and Paola — who together represent the second generation of the Conti family's viticultural legacy.
The Conti sisters have not merely inherited the estate; they have expanded it, deepened its commitment to organic viticulture, and brought a new energy to the cellar while preserving the traditional methods their father established. They have grown the family's holdings from the original single hectare to 2.5 hectares, divided into seven distinct parcels that capture the full range of Boca's volcanic terroir. Under their stewardship, the estate has become a beacon of what small-scale, family-run viticulture can achieve — wines of extraordinary precision, minerality, and authenticity that speak with unmistakable clarity of their origin.
The name "Castello Conti" evokes the medieval castle that dominates Maggiora — a reminder of the deep history of this corner of Piedmont, where viticulture has been practiced since Roman times. The Alto Piemonte is a territory of ancient volcanic soils, steep hillsides, and a climate tempered by the proximity of the Alps and the Monte Rosa massif. It is a landscape that demands patience and respect from those who farm it, and the Conti sisters have answered that demand with unwavering dedication. Their work is not about volume or market share; it is about preserving a piece of Piedmontese viticultural history and expressing it in every bottle.
"The Conti family rigorously applies organic standards to their farming, does a manual harvest and continues to apply the same philosophy to the work in the cellar. Indigenous yeasts are used in fermentation and little to no sulphur is applied during the elevage and at bottling."

Volcanic Porphyry & Seven Hillside Parcels
Castello Conti's vineyards are located in Maggiora, within the Boca DOC of Alto Piemonte — a region whose wines were once more celebrated than Barolo, before phylloxera and economic hardship reduced the area's plantings to a fraction of their former extent. The estate's 2.5 hectares are divided into seven distinct hillside parcels, each with its own exposure, elevation, and microclimate, but all rooted in the same extraordinary soil: volcanic porphyry. This ancient igneous rock, rich in minerals and free-draining, is the defining characteristic of Boca's terroir — it imparts structure, minerality, and aromatic finesse to the wines, giving them a precision and elegance that is unmistakably Alto Piemonte.
The volcanic porphyry soils of Boca are among the most distinctive in Piedmont. Formed millions of years ago by ancient volcanic activity, these soils are rich in iron, magnesium, and other minerals that contribute to the wine's complexity and longevity. They are free-draining and poor in organic matter, forcing the vines to struggle and dig deep for nutrients — a struggle that produces grapes of extraordinary concentration and character. The result is wines with a pronounced mineral backbone, vibrant acidity, and a capacity for ageing that rivals the best wines of Barolo and Barbaresco. The Conti sisters' seven parcels capture different expressions of this terroir: some higher, cooler, and more exposed to Alpine winds; others lower, warmer, and more sheltered — each contributing its own voice to the final blend.
The climate is continental with a strong Alpine influence — the Monte Rosa massif looms to the north, moderating temperatures and providing a dramatic backdrop to the vineyards. Summers are warm but rarely oppressive, thanks to the elevation (Boca sits at approximately 300–400 meters above sea level) and the cooling breezes that descend from the Alps. Winters are cold, with significant snowfall, which helps to naturally control pests and diseases. The diurnal temperature shifts during the growing season are pronounced, preserving acidity and developing complex aromatics in the grapes. Rainfall is moderate, and the volcanic soils' excellent drainage prevents waterlogging, even in wet years. This is a climate that demands patience from the vigneron but rewards that patience with grapes of extraordinary balance and finesse.
Farming is certified organic and rigorously hands-on. The Conti family uses only copper and sulfur treatments, avoiding all synthetic chemicals, herbicides, and pesticides. Vineyard management includes careful canopy management to ensure optimal sun exposure and air circulation, reducing the risk of fungal diseases in this humid climate. All harvesting is done by hand, with rigorous selection of the finest bunches. The sisters work the vineyards themselves, their hands in the soil, their eyes on every vine. This is not industrial agriculture; it is a labor of love, a conversation between three women and their land, conducted in the language of pruning, plowing, and patient observation. The result is grapes of exceptional quality — small berries with thick skins, intense flavors, and the mineral imprint of volcanic porphyry in every cluster.

Indigenous Yeasts, Extended Maceration & Little to No Sulfur
At Castello Conti, the cellar philosophy is one of minimal intervention and maximum respect for the grape. The Conti sisters continue the approach their father established: indigenous yeasts for fermentation, extended macerations to extract the full structural potential of the varieties, and ageing in large Slavonian oak casks and carefully chosen French barriques that bring complexity without overwhelming the purity of the fruit. Temperature-controlled fermentations preserve freshness and aromatic integrity, while natural yeasts and minimal sulfur guarantee authenticity and stability. The result is a portfolio of wines that are precise, terroir-driven, and expressive of the Boca denomination — structured, age-worthy reds that embody both heritage and innovation.
The techniques are traditional, meticulous, and deeply rooted in Alto Piemonte's winemaking history:
Harvest & Selection: All grapes are meticulously hand-harvested from the estate's seven hillside parcels. The Conti sisters 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 cellar to preserve freshness. The old vines of the original Ermanno Conti parcels receive particular attention, their concentrated fruit handled with the care that decades of history demands.
"Il Rosso delle Donne" Boca DOC — The Flagship: The estate's most celebrated wine is the "Il Rosso delle Donne" — "The Women's Red" — a powerful statement of identity and a tribute to the three sisters who now lead the estate. This is a traditional Boca blend, dominated by Nebbiolo (Spanna) with smaller percentages of Vespolina, Croatina, and Uva Rara — the field blend that has defined Boca for centuries. The grapes are hand-harvested, destemmed, and fermented with indigenous yeasts in temperature-controlled tanks. Extended maceration on the skins — typically 20–30 days — extracts the full tannic backbone and aromatic complexity that Nebbiolo demands. The wine is then aged for approximately three years in a combination of large Slavonian oak casks and carefully chosen French barriques, which add subtle spice and structure without masking the wine's volcanic minerality. The result is a wine of extraordinary depth: rose petal, tar, wild cherry, tobacco, and a distinct mineral earthiness that speaks of the porphyry beneath the vineyard. The tannins are firm yet refined, the acidity vibrant, the finish long and savoury. It is a wine that demands patience — 10–20 years of cellaring will reveal more truffle, dried fruit, and earthy complexity. This is not merely a wine; it is the Conti sisters' declaration of who they are and what Boca can be.
"Origini" Vino Rosso — The Field Blend Tribute: The "Origini" is inspired by the local tradition where families cultivated small vineyard parcels to produce wines for personal consumption — field blends of whatever varieties were planted, co-fermented and co-aged to create something uniquely expressive of place. The Conti sisters reclaimed and revived a half-hectare of old vines in the Novara hills, creating a field blend that reflects the region's rich viticultural heritage. Primarily Nebbiolo, with 15% of Vespolina, Croatina, Uva Rara, Dolcetto, Barbera, and other local varieties, the grapes are hand-harvested and undergo spontaneous fermentation with native yeasts. The wine is aged for approximately 15 months, with a portion in stainless steel tanks and the remainder in large old oak casks — a method that preserves freshness while adding subtle complexity. The result is a lively, approachable red with bright acidity, moderate tannins, and flavors of red berries, herbs, and a hint of spice. It is a wine that honors the past while remaining utterly drinkable in the present — a bridge between tradition and immediacy.
"Spanna" Colline Novaresi — The Nebbiolo Expression: The "Spanna" is a pure expression of Nebbiolo from the Colline Novaresi denomination — the broader appellation that encompasses the hills around Novara, including Boca. Made from selected parcels of the estate's oldest Nebbiolo vines, it undergoes the same meticulous hand-harvesting, indigenous yeast fermentation, and extended maceration as the flagship Boca. Ageing is in large old oak casks for approximately 18–24 months, followed by bottle ageing. The result is a wine of structure and elegance: rose, tar, cherry, leather, and the unmistakable mineral imprint of volcanic porphyry. It is slightly more approachable in its youth than the Boca DOC but still possesses the backbone and acidity for long ageing — a wine that speaks of Nebbiolo's Alto Piemonte soul with clarity and conviction.
Experimental Cuvées — Zero Sulfur: In addition to their core portfolio, the Conti sisters produce several experimental cuvées that are bottled entirely without the application of sulfur — a bold statement of their confidence in the health of their grapes and the cleanliness of their cellar practices. These wines represent the frontier of the estate's exploration, pushing the boundaries of natural winemaking while maintaining the precision and balance that define the Conti style. They are limited in quantity, available only to select markets and visitors, and represent the sisters' willingness to take risks in pursuit of authenticity.
Ageing & Bottling: The estate's approach to ageing is deliberately traditional. Large Slavonian oak casks (botti grandi) provide the slow, gentle micro-oxygenation that develops complexity without adding dominant wood flavors. For selected wines, carefully chosen French barriques add subtle spice and tannin refinement. There is no new oak dominance, no toast or vanilla excess — only the gift of time and the unique character of each vessel. After ageing, the wines are bottled with little to no sulfur, preserving their natural texture and layers of flavor. Several experimental cuvées are bottled entirely sulfur-free. The result is wines that are pure, unadulterated reflections of their volcanic origin — alive, evolving, and unmistakably honest.
"Il Rosso delle Donne" — "Nebbiolo, Vespolina, Croatina & Uva Rara from Volcanic Porphyry, 20–30 Days Maceration, 3 Years in Slavonian Oak & Barrique, Little to No Sulfur"
The "Il Rosso delle Donne" is Castello Conti's most profound wine — a powerful statement of identity, a tribute to the three sisters who lead the estate, and a technical masterpiece that showcases the extraordinary potential of Boca's volcanic terroir. It is not merely a wine; it is the Conti family's declaration of who they are and what Alto Piemonte can achieve when tradition, terroir, and unwavering commitment converge.
The blend is a traditional Boca field blend, dominated by Nebbiolo (locally known as Spanna) with smaller percentages of Vespolina, Croatina (Bonarda), and Uva Rara — the same combination of varieties that has defined Boca viticulture for centuries. All grapes come from the estate's seven certified organic parcels in Maggiora, on volcanic porphyry soils that present a distinctive mineral imprint in every cluster. The porphyry — ancient igneous rock rich in iron and magnesium — forces the vines to struggle, producing small berries with thick skins, intense flavors, and the structural backbone necessary for decades of ageing.
The grapes are hand-harvested with meticulous selection, then gently destemmed and crushed. Fermentation occurs spontaneously with indigenous yeasts in temperature-controlled tanks — no commercial strains, no enzymes, no additives. The maceration is notably long, extending for 20–30 days, allowing for full and gradual extraction of phenolics, aromas, and the tannic backbone that distinguishes great Nebbiolo. This extended contact with the skins is crucial for building the structure and character that allow the wine to age with grace and complexity. After fermentation, the wine is transferred to a combination of large Slavonian oak casks and carefully chosen French barriques, where it ages for approximately three years. The Slavonian oak provides slow, gentle micro-oxygenation and subtle spice; the barriques add tannin refinement and structural complexity without overwhelming the wine's volcanic minerality.
In the glass, it is deep garnet with a brick rim that hints at its ageing potential. The nose is complex and evolving — rose petal, tar, wild cherry, plum, tobacco, dried herbs, and a distinct mineral earthiness that speaks of the porphyry beneath the vineyard. There are notes of leather, truffle, and a subtle spiciness from the oak ageing. The palate is full-bodied and seamless, with firm yet refined tannins, vibrant acidity, and a long, savoury finish that lingers for minutes. This is not a heavy, over-extracted wine; it is a wine of structure, elegance, and Alto Piemonte soul — proof that Boca, when farmed with patience and made with respect, can produce wines that rival the most famous names of Piedmont.
The "Il Rosso delle Donne" demands patience. It will reward 10–20 years of cellaring, developing more earthy, truffle, and dried fruit complexity. Serve at 18°C after decanting, with braised meats, aged cheeses, truffle dishes, or simply on its own as a contemplative red. This is the wine that carries the legacy of Ermanno Conti's 1963 vision and the three sisters' unwavering devotion — from a single hectare to the world's finest tables. ~$45–$70 / ~€40–€63.
