Gianmarco Antonuzzi and Clémentine Bouveron tend around 14 hectares of land, with vineyards amongst olive groves, chestnut trees, shrubs and oaks. Sat around Lago di Bolsena near Gianmarco’s childhood town of Gradoli in Lazio’s north, the soils are volcanic, rich in iron and minerals. Each year they produce a dizzying number of different wines which are vinified in an ancient cellar in the village’s centre where nothing is added at any stage.
