Nervo

Nervo sits within the Treiso commune, one of three municipalities entitled to produce Barbaresco DOCG alongside Alba and the village of Barbaresco itself. The site occupies 3.3 to 4 hectares at elevations ranging from 310 to 370 meters, positioning it among the higher-altitude vineyards of the appellation. The full southern exposure maximizes solar radiation throughout the growing season, a critical advantage for Nebbiolo, which requires ample heat accumulation to ripen fully. The cooler microclimate associated with Treiso tempers that warmth, helping to preserve the aromatic finesse and natural acidity that define wines from this part of the DOCG.

• Treiso commune: one of three Barbaresco DOCG production zones
• Elevation range of 310 to 370 meters above sea level
• Full south-facing aspect maximizes Nebbiolo ripening
• Cooler Treiso microclimate preserves freshness and aromatic complexity

The Lequio formation underlies Nervo, one of the two principal soil types found across the Langhe hills. Lequio soils are composed of compact calcareous marl with significant sand and clay fractions, dating to the Tortonian stage of the Miocene epoch. Compared to the Helvetian Sant'Agata soils found in many Barbaresco and Barolo vineyards, Lequio tends to produce wines with somewhat more austere structure and refined tannins. The calcareous content supports vigorous Nebbiolo development while the sandy fraction aids drainage, reducing waterlogging risk on steep slopes. These geological characteristics place Nervo alongside other Treiso MGAs known for producing structured, age-worthy Barbaresco.

• Lequio formation: calcareous marl, sand, and clay of Miocene origin
• Excellent natural drainage from sandy component on sloped terrain
• Calcareous marl delivers minerality and supports Nebbiolo's tannic backbone
• Lequio soils associated with austere, refined tannin structure in Barbaresco

Nervo carries documentation stretching back to municipal maps drawn in 1906, confirming its status as a long-recognized quality site in Treiso. The formal classification system for Barbaresco MGAs, introduced in 2007, codified what local growers had understood for generations: that individual vineyard sites within the appellation produce wines of distinct character. Nervo's inclusion in the MGA framework placed it among over 60 recognized crus across the Barbaresco zone. The site is regarded as one of the well-regarded crus of the Treiso commune, a reputation backed by its combination of elevation, exposure, and Lequio soil composition.

• Appears on Treiso municipal maps from 1906
• Formal MGA status granted under the 2007 Barbaresco classification
• One of over 60 recognized MGAs across the Barbaresco DOCG
• Considered among Treiso's well-regarded historical cru sites

Nebbiolo from Nervo produces Barbaresco in an elegant, structured style with pronounced floral character, refined tannins, and a degree of austerity typical of Lequio-formation vineyards. The full southern exposure drives phenolic ripeness, while the cooler Treiso microclimate sustains aromatic lift and acidity. Wines show the classic Nebbiolo profile of roses, tar, and red fruit alongside a mineral edge contributed by the calcareous soils. Several respected Langhe producers work fruit from this MGA, including Cantina Vignaioli Pertinace, Cantina Rizzi, Rivetto, Piazzo, and Albino Rocca.

• Style: elegant, floral, structured, with refined tannins and austere backbone
• Classic Nebbiolo aromatics: roses, tar, red fruit, mineral notes
• Notable producers: Cantina Vignaioli Pertinace, Cantina Rizzi, Rivetto, Piazzo, Albino Rocca
• Full southern exposure drives ripeness; Treiso altitude preserves aromatic finesse
