Vigna Astroni lies alongside the crater of the same name, bordering the 18th-century Bourbon boundary wall commissioned by Charles of Bourbon to protect his private hunting reserve. It is a setting of remarkable historical and environmental significance, today part of the nature reserve managed by WWF Italy.

The vineyard covers approximately 1.5 hectares at an altitude of around 200 metres above sea level (40°50’52” N – 14°09’35” E). Located entirely within the municipality of Naples, it extends along the east–south-east slope of the crater.

The vineyard is divided into several terraces, planted predominantly with Falanghina, alongside a smaller proportion of Piedirosso.

The vines have an average age of approximately thirty years and are ungrafted, growing on their own roots.

The vineyard is trained using a vertical trellis system with Guyot pruning. The rows, predominantly oriented north–south, are planted at 1.80 × 1.00 metres, with a density of approximately 4,000 vines per hectare.

The soils are volcanic in origin, with a pyroclastic matrix linked to the most recent Phlegraean eruptions, which occurred between 5,000 and 3,500 years ago.

From a pedological perspective, they are characterised by a stratified structure and a neutral to slightly acidic reaction, with good levels of potassium, phosphorus pentoxide and calcium oxide, alongside a low carbonate content.

These conditions contribute to wines of remarkable tension, precision and a distinctive expression of their place of origin.
