Greco di Tufo is a DOCG of the Campania wine region in southern Italy. It is responsible for what is arguably the region's most prestigious white wine, made predominantly from the grape variety that shares its name. The Greco di Tufo grape is a clone of Greco Bianco and is believed to have been introduced to Campania by the Pelasgians, an ancient people from Thessaly in Greece. The name Tufo refers not only to one of the villages from which the wine comes, but also the type of rock on which the village was built.
The vines from which Greco di Tufo wines are made are cultivated at an altitude of 1310–1640ft (450–500m), where the cooler temperatures allow grapes to enjoy the persistent summer sunshine without overheating or having their photosynthesis shut down. This allows them to ripen without losing too much acidity, an effect magnified by the higher diurnal temperature variation here. The best expression of the Greco di Tufo vine is found on the volcanic hills of the Avellino province in central Campania, and only eight villages can legally claim to make Greco di Tufo: Tufo, Montefusco, Petruro Irpino, Chianche, Torrioni, Altavilla, Irpina and Prata di Principato Ultra.
The appellation received its DOCG status in 2003. The wines must contain a minimum of 85% Greco di Tufo grapes, and up to 15% of Coda di Volpe Bianca grapes is also permitted, at the discretion of each winemaker. A sparkling Greco di Tufo spumante variant can also be made, and must be aged for at least three years prior to release.
Greco di Tufo wines stand out from the crowd thanks to the unique characteristics of the sulfur- and tufa-rich volcanic and clay soils; it is believed that these lend the wine its perfume and mineral complexity. The refreshing, crisp white wines are known for their aromatic notes of lemons, pears and toasted almonds and a lingering mineral finish. The wines are generally at their best within three years of bottling.
