Fonterenza is an old farmhouse in the small village of Colle in Montalcino, which takes its name from a spring that flows from the hill under the house. It is now owned by twin sisters Margherita and Francesca Padovani, whose family bought the estate in 1975. The sisters are originally from Milan, but spent much of their youth here and fell in love with it. In 1997 they moved from Milan for good, initially to produce olive oil at Fonterenza, as they continue to do, from their five hectares of olive orchards. But they soon became interested in wine production as well. The first vines were planted here in 1999, starting with organic methods before moving to biodynamic principles. They increased the number of their vines in 2002 and 2005, and now have 4.2 hectares of Sangiovese. Most recently, in February 2020, the sisters acquired a new vineyard on Monte Amiata, in which they have planted eight different local varieties of white grapes.
Along the way, they have taken advice from winemaker friends, such as Thierry Puzelat and Pierre Overnoy, leading the sisters to create some truly great Brunellos.
