The Castello Sonnino with its thirteenth-century tower is a symbol of the territory of Montespertoli and overlooks the valleys of Florentine Chianti. 

Here, for over two centuries, the Sonnino family has been producing wines and extra-virgin olive oils of remarkable character, fusing a profound knowledge and love of the earth with a constant spirit of research. 

Today, Baron Leone de Renzis Sonnino steers the company along this path between tradition and experimentation, resulting in the creation of one of the most interesting wines of the new Tuscan generation.


Castello Sonnino produces wine guided by the philosophy of the great “Chateaux”, choosing to work only with the grapes grown in its own vineyards, which extend over more than 40 hectares. 

The Sonnino wines have oodles of personality and character, fruit of the particular features of a terroir which since 1997 has been endowed with the specific denomination of Chianti Montespertoli D.O.C.G, the smallest of the Chianti denominations. 

The arrival of Baron Alessandro de Renzis Sonnino in 1987 opened up new horizons: the traditional Chianti grape varieties of Sangiovese and Canaiolo were joined by Merlot, Petit Verdot, Syrah, Cabernet Sauvignon and Malbec.


The monumental cellar are inside the Sonnino castle. Built in the 17th century, they continue to be the ideal place for ageing wine in wood, barrels and barriques. 

In the old Vinsantaia, the grapes harvested in mid-September by the most experienced workers are dried for 5 months by spreading them out on mats or hanging them from hooks, in the traditional manner. 

The Trebbiano grape produces the excellent Vin Santo “Red Label”.
