Tenuta di Collosorbo, founded by Giovanna Ciacci in 1995, was part of the Tenuta di Sesta estate. Tenuta di Sesta has existed since 1850. It was one of the first estates to produce Brunello when DOC Brunello di Montalcino was created in 1966.

The winemaking process is meticulous and lengthy resulting in a deep, balanced and sophisticated wine. In the best harvest years, the Brunello di Montalcino Riserva is obtained from the meticulous selection of Sangiovese grapes from the estate’s oldest best vineyards. It is the product of diligent and thorough fieldwork and of focused operations in the wine cellar which preserve the essence of the Sangiovese grape and exalt the qualities of a wine which every bottle reflects over history and time.
