The Difference Between A Champagne And Sparkling Wine

I will be sharing my little knowledge on the difference between a champagne, and a sparkling wine in this short piece.
The term ‘Sparkling wine’ to me is a general name. All Champagne can be referred to as sparkling wine, but not all ‘sparkling wine’ can be called ‘Champagne’.
Why?
Champagne are produced in the champagne region of France. Any french sparkling wine that is produced out the Champagne region or produced in any other country like; USA, Nigeria, Italy, Germany etc can not be legally referred to as a champagne.
Example of champagnes are;
• Dom Perignon (brut, demi-sec, etc)
• Moët & Chandon ,, ,,
• Bollinger. ,, ,,
• Veuve Clicquot. ,, ,,
• Louis Roederer’s Cristal et-al.
Sparkling wine can be used as a general name for all, despite where it was produced. Now let us talk about other countries sparkling wine and what it is called.
Prosecco: These are popular Italian sparkling wines, they produce bubbles when been poured into champagne glasses just like champagnes. example are; Martini prosecco, Spumante, Frizzante, Tranquillo etc.
American sparkling wine: Americans refer to theirs as sparkling wines.
Cava: They are Spanish sparkling wine have very similar flavor to Champagnes
Sekt: They German version of sparkling wine and has different tastes just like other wines, considering how sweet and dry it is.
