ON the subject of "real" champagne---- unless it's grown, bottled in France it's only sparkling wine.

That said, we go to Pleasant Valley Winery in the Finger Lakes of NY and buy their wines. They received vines from France over 100 years ago and they cannot say it's true champagne only that it's in the "method of" on the label. So I guess just having grapes from France isn't enough. It must also have been grown, bottle there.
