The origin of the company "Le Chiuse" is very old. It was part of the possessions of the Biondi Santi family: it was in fact brought as a dowry in the late 1700s by Maria Tamanti when she married Clemente Santi. The daughter Caterina married Jacopo Biondi and their son Ferruccio, great-grandfather of Simonetta Valiani, respecting his mother's wishes and added the maternal surname "Santi" to his. It was he who, after having fought alongside Garibaldi, continued the work of his grandfather Clemente, enhancing and selecting the vines to obtain this particular clone of Sangiovese (grosso). Originally in Le Chiuse, wine, wheat and oil were produced. Tancredi, son of Ferruccio, bequeathed "Le Chiuse" and two other farms to his daughter Fiorella, exhorting her never to sell this company "because there was born the famous Brunello for the Reserves".
The farm consists of 18 hectares of woodland, vineyards and olive groves located on the north / northeast side of the hill of Montalcino at about 330 meters above sea level and on the southeast side at 500 meters above sea level. The vineyards, all in Sangiovese Grosso, are 5 with a climbing age of 26, 16, 14, 10 and 2 years, for a total of 8 hectares. The spurred cordon vines are for the most part created by a mass selection from the Il Greppo estate. The average plant density is about 4000 plants per hectare. The soil is of oceanic origin, therefore rich in fossil material. It consists of clayey streaks as well as a good presence of galestro and tuff. The result is the production of a wine characterized by an exaltation of aromas and flavors, with a beautiful body but with never excessive gradations. Le Chiuse produces almost 30,000 bottles of wine each year between Rosso di Montalcino, Brunello di Montalcino and Brunello di Montalcino Riserva.
