Whats the difference between wine and cogniac?

Wine is uncarbonated and champagne is carbonated.

Technically champagne is sparkling wine from the Champagne district of France, all other "champagnes" are just sparkling wine.

Champagne is like youth----full of spark ,exuberance and flamboyance. Wine is like old age----calm, quiet, slow on uptake. Wine is stronger since it is fermented longer than champagne.
