Well ever since Phylloxera the French wine is grown on American rootstock and the same is true for wine grown on American soil.
I guess saving the wine industry in France is big enough payment for using those names.
On the other hand, Phylloxera actually originated in America

But with a bit of research you can drink USA grown wine like Chardonel, cultivated by New York State Agricultural Experiment Station, Traminette made by Herb C. Barrett at the University of Illinois, Norton cultivated in Richmond, VA and the list goes on and on.
Not putting down French wines at all, Kev

although lately I prefer Puglias.
