The Badia a Passignano abbey is situated in Sambuca Val di Pesa, three kilometres to the south of the Tenuta Tignanello estate. The fundamental importance of this abbey in the history of Chianti Classico can be read in many volumes housed in the State Archives of Florence, which confirm the presence of a Sangiovese vineyard. Further confirmation occurred in 1983 when, in the terrain surrounding the abbey, a millennia-old Vitis vinifera vine was found.

The Badia a Passignano Chianti Classico Gran Selezione is the only Chianti made by Antinori with 100% Sangiovese (aged in Hungarian oak in the abbeys underground cellars) and is made from a selection of the best grapes from the 53 hectares owned by the family since 1987.
