You could grab some vine cuttings from the Bordeaux region of France, transplant them to Chicago, and the resulting product is not a Bordeaux.

If I recall my "vine cutting" history - - - it was sometime in the early to mid 1800's that all of the Bordeaux vinyards got some some form of root disease and they were "forced" to use root cuttings from California (because they were disease free).

Does that now mean that "the Bordeaux wines are not Californian?"

due to the famous grape blight, many of the best French wines were transplanted back from --

Chile!!!

They are hybrids. The french cuttings were grafted with mature Californian stock, which was both italian and french to begin with, then transplanted back to France after the blight left. So, yes the wines are part "Californian", but of course they are really mostly European still.
