Made from a blend of local grape varieties, which flourish on the volcanic hills south of Rome. The vineyards were completely replanted from 1990 to 1992, at a density of 5,500 vines per hectare, to limit vigour, thus concentrating the flavours in the grapes. The 25-year-old vines yield 90 quintals (9,000kg) per hectare. The vines are planted at an elevation of 300 metres above sea level and are orientated towards the south-east to maximise sunlight exposure. The linear rows of vines are cordon spur pruned, which suits the warm, dry climate. The volcanic soils are layered with granular tuffs, rich in mineral elements, producing elegant and fresh wines with a distinctive character. The hand-harvested grapes are picked at optimal ripeness.
