Barolo Commune — Diano d'Alba

Diano d'Alba's name derives from the Roman goddess Diana, and local tradition holds that a sacred grove or temple dedicated to her once stood on the hill where the town now sits. The commune's modern wine identity took shape in the 1960s, when growers began organized promotion of their Dolcetto. In 1974 Diano d'Alba became one of the first Italian communes to achieve DOC recognition for its Dolcetto, and in 1986 it became the first Italian wine area to publish an official map delimiting its best vineyard sub-zones, the Söri. This pioneering cartographic work anticipated by decades the broader MGA mapping that Barolo and Barbaresco would adopt in 2010.

• Town name linked to Diana, Roman goddess of the hunt, with traces of an ancient sacred site on the hilltop
• Dolcetto DOC recognition granted 3 May 1974, among the earliest in Piedmont
• 1986: first official Italian vineyard sub-zone map published, identifying the Söri of Diano d'Alba
• Dolcetto di Diano d'Alba elevated to DOCG on 2 August 2010, with Söri formally recognized as Menzioni Geografiche Aggiuntive

Diano d'Alba sits north of Serralunga d'Alba and south of Alba in the province of Cuneo, roughly 50 km southeast of Turin. The town center stands at approximately 500 meters above sea level, with authorized vineyards ranging from 400 to 550 meters on the surrounding hills. Soils are predominantly calcareous and sandy, rich in tufa, notably different from the compact Tortonian and Serravallian marls that dominate the core Barolo communes to the south and west. The climate is continental, with warm summers, cold winters, and the characteristic autumn nebbia, or fog, that slows late-season ripening and preserves aromatic complexity. Most vineyards face southwest, promoting consistent ripening.

• Located north of Serralunga d'Alba, bordered by Alba, Grinzane Cavour, and Serralunga d'Alba
• Elevation 400–550 m, with the town center at approximately 500 m above sea level
• Sandy, calcareous soils rich in tufa, distinct from the heavier marls of the core Barolo communes
• Southwest-facing Söri sites maximize sun exposure and allow Dolcetto to ripen fully and evenly

Dolcetto is the grape that defines Diano d'Alba. The Dolcetto di Diano d'Alba DOCG requires 100% Dolcetto and is produced in two styles: the standard Rosso and the Superiore, which requires at least ten months of aging. Wines are deep ruby with violet undertones, offering aromas of black cherry, plum, and berries with a characteristic bitter almond finish on the palate. Diano's slightly elevated position and calcareous sandy soils give its Dolcettos a particularly perfumed and fruit-driven character compared to other Dolcetto appellations. The commune also lies within the Barolo DOCG zone, and a small number of producers vinify Nebbiolo from local parcels into Barolo, though this represents a minor share of the commune's total production.

• Dolcetto di Diano d'Alba DOCG: 100% Dolcetto, ruby red with violet tints, classic bitter almond finish
• Superiore requires a minimum of ten months aging before release
• Söri-designated wines must meet higher minimum alcohol (12.5% vs 12.0% for standard)
• Barolo DOCG production from Nebbiolo also permitted but represents a small portion of commune output

Diano d'Alba's wine scene is built around small, family-run estates, with around 67 producers affiliated with the I Söri di Diano association. Azienda Agricola Abrigo Fratelli, founded by Giovanni and Maria Abrigo in 1968, is one of the best-known names, farming 13 hectares of Dolcetto, Barbera, Nebbiolo, Favorita, and Arneis across the commune. Il Palazzotto, run by fourth-generation winemaker Paolo Olivero, produces respected single-Söri Dolcettos including Sorì Cristina and Sorì Santa Lucia. Claudio Alario is another prominent estate, producing Dolcetto from multiple Söri including Sorì Pradurent, Sorì Montagrillo, and Sorì Costa Fiore, alongside Barolo from Serralunga d'Alba parcels. The Cantina Comunale (I Söri di Diano) serves as a central showcase for the commune's wines.

• Abrigo Fratelli: founded 1968, third-generation family estate farming 13 hectares sustainably
• Il Palazzotto (Paolo Olivero): fourth-generation producer, celebrated for Sorì Cristina and Sorì Santa Lucia Dolcettos
• Claudio Alario: multi-Söri specialist producing Dolcetto and Barolo from Serralunga parcels
• Cantina Comunale I Söri di Diano: local showcase wine shop offering over 53 labels from the commune

Diano d'Alba operates under two distinct DOCG frameworks. As one of eleven communes in the Barolo DOCG (established 1980, MGA system formalized 2010), Nebbiolo grown on authorized hillside parcels may be vinified into Barolo, which requires 100% Nebbiolo, a minimum of 38 months total aging including 18 months in wood, and 62 months for Riserva. Separately, the Dolcetto di Diano d'Alba DOCG (elevated from DOC in 2010) requires 100% Dolcetto with a minimum of 12.0% alcohol for the Rosso and 12.5% for the Superiore or any wine named with a Söri. The 76 Söri are formally recognized as Menzioni Geografiche Aggiuntive under the Dolcetto DOCG, making Diano d'Alba a pioneer of the sub-zone classification model that Italy has since adopted more broadly.

• Barolo DOCG: 100% Nebbiolo, 38 months total aging (18 in wood); Riserva requires 62 months
• Dolcetto di Diano d'Alba DOCG: 100% Dolcetto, min. 12.0% alcohol; 12.5% if a Söri is named on the label
• Superiore style requires a minimum of ten months aging before release
• 76 Söri formally recognized as MGAs under the Dolcetto DOCG, one of Italy's earliest sub-zone systems

The hilltop town of Diano d'Alba sits at around 500 meters, offering sweeping panoramic views across the Langhe to the castles of Grinzane Cavour, Serralunga d'Alba, and Barolo, as well as the Alps beyond. The Cantina Comunale, housed in a historic building at the foot of the Belvedere, is the ideal starting point for visitors, offering tastings across more than 50 different labels from local producers. Each autumn, the Di Söri in Söri event invites visitors to walk between vineyard sites and taste local wines alongside traditional Piedmontese foods such as tajarin with ragù, Fassona tartare, and local cheeses. Diano d'Alba is close to Alba, world capital of the white truffle, making it a natural complement to a broader Langhe wine tour.

• Town center at approximately 500 m with 360-degree panoramas of Barolo castles and the Alpine arc
• Cantina Comunale I Söri di Diano: central tasting hub with over 53 labels available on-site
• Annual Di Söri in Söri event: guided autumn walk through vineyard sites paired with local food and wine
• Close proximity to Alba (roughly 10 km), renowned for its October–November white truffle fair
