The name Sesta, of Roman origin, derives from the sixth (sesta in Italian) milestone where the Parish Church of Saint Mary of Sexta once stood along the ancient road from Roselle to Chiusi.
The Sesta Estate was formed after the expansion of the Republic of Siena. In 1850, Felice and Giovanni Ciacci became owners of the property and in 1966, the first bottles of Brunello from the Tenuta di Sesta estate were produced by Giuseppe Ciacci, father of current owner Giovanni Ciacci. At the time, there were only twelve bottlers of Brunello. For this reason, the Tenuta di Sesta estate is recognized as one of the historical Montalcino estates.
The property extends over 200 hectares, of which 30 hectares are under vine for the production of Brunello di Montalcino, Rosso di Montalcino, and Sant’Antimo wines. The remaining area is mostly covered by olive groves and grain. Since 1995, the winery has been managed by Giovanni Ciacci, who has been joined by his children Andrea and Francesca in the areas of business and agronomic management.
