As linked in WineTerroirist, a very interesting article:
on a wine produced in Beaumont in the Ardeche by a coop, called Cuvee des Vignes d'Antan.
It is made from the Jacquez (also known as Black Spanish or Lenoir) and Herbemont French-American hybrid grapes from 140 yr old vines.
More on that grape:

The EU has banned wines made from French-American hybrids, or direct producers. So this is an illegal wine.

Anyway...rather interesting on esoteric grapes.
