Why it matters
The producer
Fratelli Serio & Battista Borgogno farms three hectares at the centre of Cannubi, the most debated single-vineyard cru in Barolo, and has done so without interruption since 1897. The estate is small and the range is compact: a flagship Barolo Cannubi, a Langhe Nebbiolo, a Barbera d'Alba Superiore, a Dolcetto, and a Langhe Nascetta white from a rare indigenous Piedmontese grape.
What sets the estate apart is not the address alone but what the family does with it. Fermentation happens in large wooden vats. Ageing happens in large Slavonian oak casks, each holding 25 to 50 hectolitres, which transfer slow, even oxygen contact without the vanilla or toast of smaller barrique. Every vintage, the three Cannubi parcels, named Gourat, Battista, and Nuova, are tasted separately and blended from scratch. No locked formula carries forward from one year to the next.
Place and vineyards
Where the wines begin
Cannubi sits between the communes of La Morra and Barolo village in the Barolo DOCG, the appellation built around Nebbiolo in the Langhe hills of Piedmont. It faces south to southwest on a saddle of land that rises and falls between two geological formations, a position that has made it one of the most argued-over vineyard names in Italy.
Barolo produced from Serralunga d'Alba, on its compact Helvetian soils, tends toward power and density. Barolo from La Morra, on looser Tortonian marls, tends toward aromatic lift and earlier approachability. Cannubi sits at the junction and draws from both. The wines are perfumed and long-lived without the sheer weight of a Serralunga. They open sooner than a typical Castiglione Falletto but carry more grip than the softest La Morra style. That middle character is not accidental; it is written into the geology.
In the cellar
Vineyards and cellar
The three hectares on Cannubi are divided across three named parcels: Gourat, Battista, and Nuova, positioned on three main sides of the hill. The Nebbiolo from each parcel is fermented and aged separately before the annual blending decision.
Fermentation takes place in large wooden vats with frequent remontage, the pump-over technique that submerges the grape solids and extracts colour and tannin. The maceration runs for 30 to 40 days, which is at least twice the minimum legal requirement for Barolo and longer than most traditionally styled producers use today. The extended contact pulls deep tannin from the skins and builds the backbone that the wine needs for a decade of ageing.
Wines to know
The range in view
The Barolo Cannubi DOCG is the estate's central wine. It is 100% Nebbiolo from Gourat, Battista, and Nuova, blended annually. The nose on the 2021 opens with raspberry, balsamic, and a mineral thread. On the palate the wine is medium-bodied with firm, angular tannins, refreshing acidity, and a long finish. Jancis Robinson scored it 17.5+ out of 20; Decanter gave 92 points in 2025. It is drinkable over the next 10 years and remains approachable but far from its peak.
The Langhe Nebbiolo DOC is the estate's Nebbiolo entry point, carrying the broader Langhe appellation label rather than Barolo DOCG. It draws on the same grape but without the extended maceration and prolonged oak programme of the flagship.
A useful way in
A bottle to begin with
Start with the Barolo Cannubi DOCG. It is 100% Nebbiolo from three parcels on the centre of Cannubi, fermented in wood for up to 40 days and aged in large Slavonian oak for 30 months. The 2021 opens with raspberry, balsamic, and mineral on the nose, then delivers medium body, angular tannins, and a long acid-driven finish. No barrique sweetness, no soft early fruit. The wine is precise in a way that only shows once the tannins begin to knit, which takes years. Buy it now, drink it over the next 10 years, and the combination of Cannubi's geological midpoint and the Borgogno cellar programme will be legible in every sip.
