Tenuta di Collosorbo was started in 1995 by Giovanna Ciacci from the division of her family’s estate, Tenuta di Sesta, which was founded in 1850.
The Ciacci family always cultivated grapes, olives, and all types of grains. Giuseppe Ciacci bottled the estate’s first Brunello di Montalcino in 1966, the same year that the Producers Association was established and the estate’s Brunello was given a DOC label.

Nowadays, Giovanna Ciacci and her two daughters run the winery, maintaining the family crest as a tie to the past.

Giovanna takes care of the general administration of the winery. Laura Sutera Sardo works as both the enologist and viticulturist. 

Lucia Sutera Sardo, the agronomist, is responsible for the commercial side of the winery
