Black grape variety grown in Apulia

Greco Nero n.

The vine Greco Nero n. was introduced in Apulia from Calabria. It is registered as suitable for cultivation in the Central Murgia and in Capitanata.

Origin and Historical Outline

There is no certain information on the origin of the Greco Nero vine n. and its subsequent spread. According to Mazzei A. and Zappalà A. the Calabrian Greco Nero is different from the homonymous cultivated in the province of Avellino, in Abruzzo, in Lazio, in Umbria, in the Marches, in Tuscany. Many years of research carried out on the Calabrian territory and realizing appropriate fields of varietal comparison (Antonacci D., Placco L., 1997) has ascertained its difference from the vine Marcigliana or Marsigliana, previously considered synonymous. The vine Greco Nero n. was then introduced in Apulia, coming from Calabria.

The Greco Nero n. vine is present in central-southern Italy and particularly in Calabria, where it is included in several cases in the production specifications for PD wines.
