110 ha, of which 45 ha are planted with vines with a view to protecting biodiversity and not homogenizing. The top of the hill of Madonna della Rosa, covered with forest of oaks, heather and junipers, slopes down to the entrance of the winery, in terraces straightened by dry stone walls, destined since ancient times for the cultivation of vines. Hedges, an important shelter for fauna are here and there maintained to protect a wealth of species, necessary for the balance of the place. Even the choice of rooted cuttings different by clone and different by rootstock has as its objective to enrich biodiversity. On the opposite slope, Monte Delma, walnut trees, chestnut trees and arable parts of the flat area facing north enrich the property. Cherry trees and fruit trees in general extend the richness of the place. Biodiversity is also protected in the cellar where indigenous yeasts selected by Nature over the centuries and which Villa Franciacorta has patented and protected have been enhanced. Clones are reproduced every year by the University of Florence and used in the cellar in first fermentation on all bases and in refermentation on some reserves, a fermentation that could therefore be said to be spontaneous but managed according to a protocol that guarantees the absolute quality of the final result.
