The Astroni’s vineyard is located close to the homonymous crater, on the border with the eighteenth-century Bourbon boundary wall erected by Charles of Bourbon in defense of his personal hunting reserve, today a natural oasis managed by the WWF.

The vineyard covers about 1.5 hectares at an altitude of about 200 meters above sea level. With topographic reference of 40°50’52” N latitude, 14°09’35” E longitude, it is entirely distributed in the municipality of Naples and is located on the east – south-east side of the crater. The vineyard is divided into several terraces, on which there are mainly Falanghina vines with a small presence of Piedirosso grape vines.

The vineyard has an average age of thirty years, is ungrafted and is arranged in espalier with guyot architecture. The rows tend to be oriented north-south, with layouts of 1.80 m x 1 m and have a density of 4000 plants/hectare.

The soils have a volcanic origin and a pyroclastic form, certainly linked to the Phlegrean eruptions between 3500 – 5000 years ago, and are defined by a layered subacid or neutral reaction lithological structure, with a major quantity of potassium, phosphorus, calcium oxide, and also reduced carbonates.
