so agree about the invented / stumbled upon part .
If you were to produce an excellent sparkling wine which sold millions of bottles and named it
champagne , then i would guess the fine people of the 5 areas allowed to name their sparkling wine as champagne, would come a knocking with a big Nebuchadnezzar of sparkling champers to politely tell you to change the name of your produce.
This is normally the case with product of originality produce.
