The family is collaborating with the University of Florence to amass a data bank of various ancient and autochthonous grape varieties. This important project was facilitated from the outset by the late Grato Grati, who planted new vines using old grafts, so that the numerous grape varieties on Grati land were preserved. The project ‘Recupero, Conservazione e Valorizzazione del Germoplasma Viticolo nel Territorio Chianti Rufina’, or ‘Preservation, Conservation and Analysis of grape vine germoplasm in Chianti Rufina’, has since been taken over by Gualberto, who is proudly amassing a great number of ancient and rare varieties in a vine nursery, with varieties as meticulously labelled as a museum.
