Castello di Bossi is located in the southern half of the Chianti Classico production zone, in the Comune of Castelnuovo Berardenga. The first tower, built in the 1090, shows the area’s wearily strategic importance. In the 1450 the original structure was expanded into the 4 walled fortress visitors can see today. Castello di Bossi estate extends over 500 hectares, 120 of which are under vine. The average elevation of the vineyards is about 350 metres above sea level, while their exposure varies from southeast to west. The Sangiovese tends to be fuller and more highly structured than the ones of the rest of the Chianti Classico thanks to the mild climate of the area. The Cabernet and Merlot where planted about 40 years ago and probably are some of the oldest vines of this varietals planted in the Chianti Classico. The predominant soils are tuffs, yellow clays, calcareous sands and broken stones.
