Named for the ancient parish church of Saint Mary di Sexta at the sixth mile marker on the Roman road from Roselle to Chiusi, the Sesta property is first mentioned in documents dating to 714 AD. After passing into the control of first one and then another Medieval abbey, the Sesta estate was formed under the Republic of Siena after the suppression of the Abbey of Sant’Antimo by the Pope (the former bishop of Siena) in 1462. After passing under the control of the noble Sienese Tolomei family for several centuries, the estate was purchased by brothers Felice and Giovanni Ciacci in 1850.

Descendant Giuseppe Ciacci produced the first Brunello di Montalcino from the estate in 1966, when it was one of the original twelve producers in the region. Today, Giuseppi’s son Giovanni, with the help of his own children, Andrea and Francesca, manage the estate and produce absolute standards for Brunello and Rosso di Montalcino.

The estate covers some 400 acres, of which 132 are under vine, the remainder planted to wheat (on the flatter land) and olive groves.
