At a wine seminar I attended a few years ago we primarily had wine from Bethlehem and the general Palestine region. The importer told us that the wine culture there is some thousand years old (which of course it is, at least there is a tradition to turn water to wine ;-)); but he also said that some grape farmers are growing grapes [again] that are as genetically close to the grapes from said water-to-wine era as possible.
(I would love to give a citation, but couldn't find one within 2 minutes - so take this as hear-say; though the importer, which is a good friend of a good friend, seemed to be not the kind of person to make this up)
