Collosorbo was founded in 1995 when Giovanna Ciacci inherited part of Tenuta di Sesta, a farm and wine estate that had been in the Ciacci family since 1850. Giovanna’s father Giuseppe had bottled the first of Tenuta di Sesta’s commercially sold Brunellos in 1966, and Giovanna grew up learning about farming and winemaking. Today Giovanna shares the estate’s operation with her daughters Laura and Lucia, who both graduated from the University of Florence in viticulture and agronomy. Collosorbo makes well-reviewed Brunello di Montalcino and Rosso di Montalcino, as well as several red blends.
