Castello di Bossi is located in the southern half of the Chianti Classico zone, in the commune of Castelnuovo Berardenga. There, the wines tend to be fuller and more highly structured than those from the rest of Chianti Classico. The estate comprises 650 hectares, 124 of which are under vine with with Sangiovese, Cabernet Sauvignon, and Merlot on terrains of tuff, yellow clay, calcareous sand, and broken stone.
The vineyards have an average elevation of about 1150 feet above sea level with various exposures from southeast to west. At the center of the estate is the Bossi Castle whose first tower was built around 1099 and was expanded in 1450 into the 4-walled fortress visitors can see today.
Inscriptions from the 1st and 2nd centuries AD indicate that the Bossi area was the site of a Roman settlement and its name seems to derive from the money chest, made of rare and prized boxwood, which the Roman army carried to its encampments to pay the soldiers.
Historic documents reveal that vineyards already existed in Bossi around 1200, since a portion of rents and leases was paid in kind, and wine was cited among the listed products. The estate has evolved with the times and embraced modern technology. The the Bacci family have introduced modern production methods and better management practices, leading to a rebirth for the Castello.
