Ca' del Baio

Ca' del Baio is one of Barbaresco's most admired family estates — a domaine that has spent three generations building a body of work defined by precision, restraint, and a meticulous understanding of the Treiso terroir. The Grasso family has farmed the hills above the village of Treiso since the 1950s, and today the estate is run by Giulio Grasso and his daughters Paola and Valentina, who have refined their father's approach while maintaining its essential character.

The estate's vineyards are spread across three of Barbaresco's most celebrated crus — Asili, Vallegrande, and Pora — each producing wines of distinct character that together offer a comprehensive portrait of what Treiso's Tortonian marl soils are capable of. The Asili cru, shared with a handful of other producers including Bruno Giacosa and Gaja, is among the most prestigious sites in the entire appellation, producing Barbaresco of extraordinary aromatic complexity and longevity.

What distinguishes Ca' del Baio from many of its neighbours is a commitment to expressing the individual character of each vineyard without imposing a house style. The three single-vineyard Barbarescos are vinified separately, aged in different proportions of large botti and smaller barriques depending on the character of the vintage, and released only when Giulio and his daughters judge them ready. The result is a range of wines that rewards comparison as much as individual contemplation.

Treiso is the southernmost of Barbaresco's three communes — the others being Barbaresco itself and Neive — and its soils are predominantly Tortonian marl: compact, calcareous clay that gives Nebbiolo wines of elegance and aromatic precision. The commune sits at slightly higher elevations than the village of Barbaresco, which moderates the summer heat and extends the growing season, allowing the grapes to develop the aromatic complexity that distinguishes great Barbaresco from merely good Barbaresco.

The Asili cru, on a south-facing slope above the village of Barbaresco, is the most celebrated of Ca' del Baio's three sites. Its compact Tortonian marl produces Nebbiolo of extraordinary aromatic complexity — rose, dried violet, iron, and a mineral depth that carries the wine for two decades or more. The Vallegrande cru, on a gentler slope in Treiso, gives wines of greater approachability in youth, with a more immediately expressive fruit profile and a silkier texture. Pora, the third cru, sits between the two in style — structured enough to age, but with a generosity that makes it one of the estate's most versatile wines at the table.

The Grasso family farms all three sites sustainably, with cover cropping between the vine rows to maintain soil health and biodiversity. Yields are kept low through careful canopy management and, in ripe vintages, green harvesting. The grapes are hand-picked at full phenolic maturity — a standard that requires patience in cool years but produces wines of exceptional concentration and complexity when the vintage cooperates.

Winemaking at Ca' del Baio is guided by a single principle: the wine should express the vineyard, not the cellar. Fermentation takes place in temperature-controlled stainless steel tanks with indigenous yeasts, with maceration lasting two to three weeks depending on the character of the vintage. The three single-vineyard Barbarescos are vinified separately from the moment of harvest, and the ageing regime for each is adjusted to suit its natural character.

The Asili, the most structured of the three, spends the longest time in large Slavonian oak botti — up to 24 months — before a further period of bottle ageing before release. The Vallegrande and Pora spend a shorter time in a combination of botti and smaller barriques, which gives them a slightly more approachable texture in youth without compromising their ability to age. All three wines are released at least four years after the harvest, and the Asili is often held back for a fifth year before the estate considers it ready.
