Located in Campania, Feudi di San Gregorio is one of the leading wineries in southern Italy.

Founded in 1986, Feudi di San Gregorio today produces 3.5 million bottles annually from vineyards covering 300 hectares in the Irpinia region.

It is owned and operated by the Capaldo family. A high-quality, modern approach is taken to restore and revamp local wine production at Sorbo Serpico in the province of Avellino.

Many Italian producers replaced old vines with international grape varieties, but Feudi di San Gregorio held true to the local heritage and cultivated native varieties such as white Greco di Tufo, Fiano di Avellino, Falanghina, and red Aglianico. There is a wide range of wines that are produced in their vineyards today, but their most renowned product is Irpinia Aglianico DOC "Serpico", a powerful red wine made from their historical Dal Re vineyard.
