Danny Gold taught Champagne 101 this morning.

Champagne/Sparkling Wines in order from dry to sweet:

Champagne comes from Champagne, France all others are Sparkling. If you see a bottle of non French Champagne marked Champagne it must be followed by the term “Methode Champenoise” meaning they make it in the same process.
 
Cava is the equivalent to Spanish bubbly done “Methode Champenoise”
Prosseco is the equivalent to Italian bubbly done “Methode Champenoise”
