White wine grape variety grown in Apulia
The vine Grillo b., cultivated for a long time in Apulia, is registered as suitable for cultivation in Murgia Centrale and Arco Jonico Salentino.
It seems that the ancient grape variety from wine to white fruit, the Grillo b., had its origin in Apulia. After the phylloxera invasion it found some diffusion in Sicily. From the bibliography we learn that the vine was widespread in the province of Trapani since 1897 (Rizzo, 1951).
In Puglia it has become, over time, less and less important.

The Grillo b. vine is currently used in Apulia generally only for wine production (in the past, however, it was also partly used for fresh consumption).
The Grillo b. vine is present in Apulia sporadically, in the old vineyards. It is registered among the vines suitable for cultivation in the production areas of the Murgia Centrale and the Arco Jonico Salentino.
