This group has dozens of messages on Zinfandel and Primitivo, ending with agreement that they are the same variety, but perhaps clones, slightly different as a result of many years growing separately in California and Italy.
But no one mentions the species. Are they Vitis vinifera or what?
p.s. Outside of the US and Canada, virtually all wine production is from v. vinifera grapes. You would be hard pressed in many wine stores to find any wine not made from v. vinifera grapes.
Just do a Google search on the words Zinfandel and vinifera and you'll get a number of reference material links including Dr. Meridiths work on the DNA link between zinfandel, primitivo, plavic mali, etc.
Actually hybrids are OK according to EU and are produced in many countries.
But national legislation in France, Spain and Italy forbids even the planting of hybrids by a wine producer. No wine can be made from hybrids here.
This does not mean that none are produced. In Ardeche an association of rebel winemakers produces small quantities of "forbidden" wines from the usual suspects: Clinton, Noah, Jacquez, Herbemont, Othello, Isabelle.
In Italy the home production of Clinton is huge, and readily found in some bars, but totally illegal.
So it is not just VdP or better, NO wine here can be from hybrids.
Thanks for the suggestion. I had been searching on just "Zinfandel," "Zinfandel+species."
You were right on: "Zinfandel+vinifera+Meridith" turned up the article "Liquid assets: DNA ends the Zinfandel intrigue" by Frank Prial, Sept

It's all there:
Zinfandel is definitely of the Vitis vinifera
Zinfandel and Primitivo are the same variety
Zinfandel and the Croatian variety, Crljenak kastelanski are the same.
Crljenak kastelanski is pronounced "tsurl-YEN-ak kastel-AHN-ski" (always wondered about that since first reading that name).
Plavac mali is a "son of Zinfandel," a cross between Crljenak and the Dobricic grape. Thus, it is not the Zinfandel/Primitivo variety.
So appreciate all who have provided feedback to my question. I'm comfortable that we have the correct documented answer.
Only disappointing news in that document is that Dr. Carole Meredith has retired from the University of California at Davis. I really appreciate her detective work and expect that it could be used in a few other instances.
