History
The earliest castle tower dates to 1099. By 1450, Castello di Bossi had assumed the form of a quadrilateral fortress.
The castle was destroyed by Florentine troops in 1478. Across subsequent centuries the property belonged to prominent Tuscan institutions and families, including the Ricasoli, Ugurgieri and Piccolomini families and the Santa Maria della Scala Hospital.
Marco Bacci acquired Castello di Bossi in 1984. The property became the centre of the Bacci Wines project and the family’s principal Chianti Classico estate.
The castle and agricultural buildings have since been restored and integrated with the winery, organic vineyards, hospitality facilities, wine bar and estate experiences.
Terroir
Castello di Bossi lies at Castelnuovo Berardenga in the southern sector of Chianti Classico.
The estate extends over more than 500 hectares, including approximately 120 hectares of vineyards. The vineyards lie at an average elevation of approximately 350 m and face from south-east through south to west.
The official estate material identifies a varied soil composition that includes tuff, yellow clay, silty sands and broken stone. These differences support separate cultivation and vinification of Sangiovese, Merlot and Cabernet Sauvignon.
The vineyards surround the medieval castle and are integrated with olive groves, woodland and the wider agricultural landscape.
Winemaking
Castello di Bossi is certified organic.
The estate uses renewable energy. A four-hectare solar installation is maintained with the aid of grazing local sheep, linking energy generation with agricultural land management.
The wider Bacci Wines philosophy combines protection of the historical landscape with organic cultivation and research adapted to the individual Tuscan estates.
The official estate materials describe a combination of tradition, research and contemporary cellar control.
Sangiovese, Merlot and Cabernet Sauvignon are managed separately according to vineyard, grape variety and intended wine. The range includes Chianti Classico, Riserva and Gran Selezione, two major Toscana IGT reds and Vin Santo.
The available public pages do not provide one consolidated description of fermentation temperatures, yeasts, maceration lengths, oak formats, filtration or bottle aging for all wines.
Philosophy
Castello di Bossi presents itself as a union of historical continuity and forward-looking research.
The estate’s philosophy is to maintain a deep bond with its territory and centuries of history while using organic farming, renewable energy and modern technical work to pursue quality.
Wine, hospitality, architecture and landscape are treated as parts of one estate identity rather than separate activities.
