man bad example, you know i live in France ;) Champagne can only be from France and from the same region, there is appellation contrôlée to guarantee that and in most civilized countries its illegal to to sell anything else under that name so its not an argument its a fact. even when you plant the same grapes elsewhere and follow the same process the soil is different, the climate and weather are different, the water is different, the end result is not the same. some Californian whites are good examples of that. sure there are other sparkling wines that are great eg from Italy but none of them are Champagne.
