White wine grape variety grown in Apulia

Chardonnay b.

A variety of important national and international distribution, also widespread in Apulia, where it is listed among the varieties to be cultivated throughout its territory.

Origin and Historical Outline

Wine grape variety of important national and international diffusion, well present also in Apulia.  Originally from France, it was initially confused with Pinot Blanc, from which it was distinguished by the name of yellow Pinot. In a research (Bowers J. et al., 1999) conducted on over 300 vine varieties, characterizing as many as 32 micro satellite loci, it emerged that as many as 16 wine grape varieties cultivated for a long time in the north-east of France, including Chardonnay, have common origin from only two parents: Pinot and Gouais blanc.
