White grape variety cultivated in Apulia

Greco Bianco b.

The Greco Bianco b.grape variety, a white-fruited wine grape, has Calabrian origins; it has been successfully tested in Apulia and is suitable throughout Apulia.

Origin and Historical Outline

The white grape variety Greco Bianco b. has been cultivated for a long time in Calabria, especially in the province of Cosenza.

In the 1881 issue of the Ministry of Agriculture, Industry and Commerce, it is reported as “Greek White”. Ampelographic, ampelometric and cultural observations, completed by DNA investigations, have shown that this is a completely different grape variety from the Greco di Tufo or Greco b.,  Greco di Gerace and Greco di Cirò. After appropriate experimental observations conducted in various territories of the region, the vine Greco Bianco b. has come and began to spread in Apulia.
