How King Tut Got So Funky

Apparently it was white wine:

White Wine Turns Up In King Tut's Tomb (USA Today)

Actually, it was white and red wine, but mostly white. The fact that some of it was labeled as coming from a vineyard near Alexandria makes me wonder: Was it 'Muscat of Alexandria'? The cultivar is undoubtedly ancient, and Egyptian, so it's a distinct possibility. I just think it's tremendously cool that through the wonder of vegetative propagation, we can eat virtually the same grapes and drink virtually the same wine as King Tut (okay, probably the wine-making is a little different, but still...) I wonder if there's enough residue to do DNA testing?
