Irpinia is an excellent wine area on the national level. Here, 3 out of the 4 DOCGs in Campania are produced.  It is a unique and very special upper hill territory marked by the presence of different geological origins. It is formed by a limestone substrate, like much of the Apennine ridge and connected hills, with layers of clay and schists Today the vineyards in the area grow at different altitudes, from 300 to 650 metres, with varying exposures and soils. Some hills are clayey and poor in limestone, but rich in volcanic materials (Vesuvius and Campi Flegrei), and others are marly with mostly sandstone and limestone. One characteristic type of soil is grey tuff from Campania, of volcanic origin. The territory coincides with the province of Avellino, it is blessed with southern sunshine, where some of the best southern Italian reds and whites are produced. The main red grape in Irpinia is Aglianico, used to produce DOCG Taurasi wines. Taurasi is also known as the Barolo of the south, due to its evolved character, strength and longevity. But in Irpinia we can also find red wines produced from local varieties such as Piedirosso, Sciascinoso, while international grape varieties are quite rare.
