Giacosa
ja-KO-za
A high-altitude MGA in Treiso where Nebbiolo produces elegant, finesse-driven Barbaresco with distinct sandy-marl soils and cool continental conditions.
Giacosa is a recognized MGA within Barbaresco DOCG, situated on steep hilltop sites in the Treiso commune at 400-500 meters elevation. Formerly known as Bricco Spessa, it was officially renamed in 2008 to avoid confusion with similarly named vineyards. The sandy Lequio soils and cooler temperatures produce lighter-bodied, aromatic Nebbiolo with notable finesse.
- Official MGA name since 2008, previously known as Bricco Spessa
- Located in Treiso, the highest and coolest of the three Barbaresco communes
- Elevation ranges from 400 to 500 meters on steep slopes
- Soils derive from the Lequio formation with higher sand content plus marl and clay
- One of 66 officially recognized MGAs in Barbaresco DOCG, established 2007-2010
- Exclusively planted with Nebbiolo
- Wine style is known for finesse, lighter body, and aromatic elegance rather than power
Location and Setting
Giacosa sits within the commune of Treiso, the southernmost and most elevated of the three communes permitted to produce Barbaresco DOCG. Perched on steep hilltop terrain at 400-500 meters above sea level, the vineyard occupies one of the higher altitude sites in the entire appellation. The Tanaro River provides a slight maritime moderating influence on an otherwise continental climate, but Treiso's elevation keeps temperatures notably cooler than the lower-lying Barbaresco and Neive communes. This cooler growing environment extends the ripening season for Nebbiolo, contributing to the site's reputation for elegant, finesse-driven wines.
- Parent commune: Treiso, within Barbaresco DOCG
- Elevation: 400-500 meters, among the highest in the appellation
- Continental climate with slight maritime moderation from the Tanaro River
- Steep slopes promote drainage and sun exposure for Nebbiolo
Soils and Viticulture
The soils of Giacosa derive from the Lequio geological formation, a characteristic of Treiso that distinguishes it from the Helvetian soils more common in Barbaresco and parts of Neive. Lequio soils carry a higher proportion of sand alongside marl and clay, which influences both vine stress and aromatic development. The sandier texture promotes earlier drainage and can moderate vine vigor, yielding grapes with concentrated flavors and a distinctive aromatic finesse. These soil characteristics, combined with the elevated and cool site, are central to the MGA's identity and the lighter-bodied style of its Barbaresco.
- Lequio formation soils with elevated sand content
- Marl and clay components provide structure and water retention
- Sandier soils compared to Helvetian-dominated areas of the appellation
- Soil composition contributes to aromatic finesse and fruit concentration

Giacosa holds official status as one of 66 Menzioni Geografiche Aggiuntive (MGAs) recognized within Barbaresco DOCG, a classification system developed between 2007 and 2010 to formally acknowledge the appellation's distinct vineyard sites. The MGA was previously designated Bricco Spessa, a name referring to its hilltop character. A 2008 renaming resolved confusion with several other 'Bricco' named vineyards elsewhere in the Langhe and Barbaresco zone. The site's quality was recognized as far back as the late 19th century in early vineyard classifications of the Langhe, giving Giacosa a documented history as a superior growing site predating the modern MGA system.
- Officially renamed from Bricco Spessa in 2008
- One of 66 recognized MGAs in Barbaresco DOCG
- MGA system formally established between 2007 and 2010
- Historical vineyard recognition dates to late 19th century classifications
Nebbiolo from Giacosa produces lighter-bodied Barbaresco with smooth tannins and concentrated fruit. Expect tar and black cherry on the palate alongside rose petal aromatics, vanilla, and an exotic, spiced character. The cooler elevation and sandier Lequio soils emphasize finesse and aromatic precision over the broader structure found in lower-altitude Barbaresco sites.
