Great article Tricia. However your info about Primitivo/Zinfandel is outdated. It now seems that the earliest known name of the variety is Tribidrag, and its origin is Croatia. See Jancis Robinson's Wine Grapes for a detailed description of the historical and genetic evidence for this.
Thanks for the update Darby
Here is Jancis Robinson Purple Pages description: "Tribidrag, Pribidrag, Crljenak, Primitivo and Zinfandel are one and the same variety."
