Castello di Bossi

History

Medieval origins

The architectural history of Castello di Bossi begins in 1099, the date assigned to the castle’s first tower. Its original function was defensive. In 1450 the building acquired the form of a quadrilateral fortification, establishing the basic historical profile retained by the estate.

Marco Bacci and the modern estate

Marco Bacci purchased Castello di Bossi in 1984. Born in Florence in 1959 and initially active in the fashion business, he first approached the property as a passion project; it subsequently became both his home and the foundation of his life in wine.

The first Corbaia was created in 1985, one year after the acquisition. In 1998 Bacci made a decisive professional transition: wine ceased to be a secondary pursuit and became his principal occupation.

Bacci Wines era

Castello di Bossi became the central estate and production hub of Bacci Wines. The property now encompasses 500 ha, including 120 ha of vineyards, in the southern part of Chianti Classico at Castelnuovo Berardenga.

In 2019 entrepreneur and innovator Serg Bell joined Bacci Wines as a minority partner. He aligned with Marco Bacci’s program of combining wine quality, environmental responsibility and an international outlook. Marco Bacci continues to lead the business with assistance from his children.

Terroir

Castello di Bossi occupies a privileged position in the southern sector of Chianti Classico, within the municipality of Castelnuovo Berardenga. The estate’s vineyards have an average elevation of 350 m above sea level and exposures ranging from southeast through west.

The site has a temperate microclimate conducive to complete grape ripening. Its varied soils are dominated by tuff, yellow clay, silty sand and broken stone. This combination of exposures, climate and geological diversity supports full phenolic and tannic maturity in Sangiovese, Cabernet Sauvignon and Merlot.

Sangiovese grown in the Castelnuovo Berardenga setting is associated with structure and depth while retaining finesse, balance and elegance.

Winemaking

Organic cultivationThe estate vineyards are cultivated using organic methods, and current Castello di Bossi labels carry organic certification.

Sustainable energyOrganic vineyard management is paired with the use of sustainable energy across the operating program.

Ripeness-oriented siteSoutheast-to-west exposures and a temperate microclimate encourage complete phenolic and tannic ripening.

The vineyards are cultivated using organic methods. Organic certification is also displayed across the current Castello di Bossi range, although a certifying organization and initial certification year are not identified.

The broader operating program couples organic cultivation with sustainable energy. The viticultural objective is complete and balanced ripening: vineyard elevation, exposures from southeast to west and the temperate Castelnuovo Berardenga microclimate favor phenolic and tannic maturity in the principal varieties.

Philosophy

Castello di Bossi places continuity and experimentation side by side. Its approach is built around respect for the property’s history and landscape, combined with ongoing research and a willingness to innovate.

The wider Bacci Wines philosophy defines its objective as producing high-quality organic wines while respecting both the environment and tradition. Landscape preservation, sustainability and consistent quality standards form part of that program. Marco Bacci’s direction also emphasizes rigor, a close relationship with terroir and a distinct house style, while Serg Bell’s participation adds an explicitly international outlook.
