Castagni

Castagni sits within the commune of La Morra, one of the most celebrated zones in the Barolo DOCG. The vineyard is compact at just 1.7 hectares, placing it among the smaller MGAs in the appellation. Its south to southeast aspect ensures excellent sun exposure throughout the growing season, and the elevation range of 370 to 450 metres provides meaningful diurnal temperature variation. These conditions together support the development of ripe fruit while preserving the acidity that defines quality Barolo.

• Located in La Morra, western side of the Barolo DOCG
• One of the smallest MGAs in the appellation at 1.7 hectares
• Elevation of 370 to 450 metres provides diurnal temperature swings
• South to southeast aspect maximises ripening potential for Nebbiolo

The soils at Castagni are characteristic of the Tortonian geological epoch, which dominates the La Morra and Barolo communes on the western side of the appellation. Blue-grey marl, clay-limestone, clay, and fine sand compose the vineyard floor. Tortonian soils are generally more fertile and have a higher clay content than the Helvetian soils found in Serralunga d'Alba and Castiglione Falletto. This difference translates directly into wine style: La Morra MGAs, including Castagni, tend to produce earlier-maturing Barolo with a rounder texture and more expressive primary fruit compared to the firmer, more structured wines from the eastern communes.

• Tortonian blue-grey marl is the defining geological substrate
• Clay content supports water retention and early fruit development
• Fine sand contributes to aromatic lift and textural elegance
• Contrasts with Helvetian soils of Serralunga, producing softer, earlier-maturing Barolo

Nebbiolo from Castagni delivers a style consistent with the La Morra commune's reputation for approachable, fruit-forward Barolo. Black fruits form the core of the aromatic profile, complemented by white pepper, tobacco, and fresh thyme. The wines show elegance and finesse rather than the austere tannic structure associated with Serralunga. Despite their relative accessibility, they retain the firm acid backbone and complexity that distinguish Barolo from other Nebbiolo-based wines. This makes Castagni an excellent introduction to the appellation for those exploring La Morra's house style.

• Black fruit-driven with white pepper, tobacco, and fresh thyme
• Elegant and fruit-forward compared to eastern Barolo communes
• Firm acidity preserved by elevation and diurnal temperature variation
• Earlier-maturing style relative to Serralunga MGAs

Given Castagni's small size of 1.7 hectares, only a handful of producers hold holdings in the vineyard. Michele Reverdito, Alberto Voerzio, and Luigi e Massimo Veglio are the key names associated with the MGA. These producers represent La Morra's tradition of crafting Barolo that emphasises aromatic expression and textural polish. Their work in Castagni provides wine professionals and students with benchmarks for understanding how Tortonian soils and a favourable aspect shape the La Morra style within the broader Barolo appellation.
