A dream is born after 20 long years. 
Our historical vineyard is located 400m above sea level; here there is galestri and palombini, and the terroir is wild, it's natural.  The story begins with Guglielmo, the grandfather - one of the founding members of the consortium of Brunello, and today is realized by his son's daughter, Ilaria, and her husband, Mike.
 Among the characteristics of our cru, there is the view of the city of Siena, together with l the sea breeze that rises from the west - from the Maremma - and gets mixed, full of suggestion with the sylvan scent of the nearby woods.
San Guglielmo is a family business and can not be otherwise; it is our land, our vineyard. It's our heritage. All phases of the wine's production from the vineyard to the cellar and until bottling are given our maximum attention, our devotion. Sustainable production is our constant pursuit.
This inaugural bottling allows us a total production of Brunello di Montalcino DOCG (2016) and Rosso di Montalcino DOC (2019),  a total of 11000 bottles. The vintages were, obviously, different, and yet the same - fantastic. 
In this moment, a glass of our wine fills us with pride and makes us hopeful for the future;  dreams can become wonderful realities. 
We invite you to join us.
