Champagne, the traditional bubbly, is produced only in the Champagne region of France. Our pick? Perrier-Jouet with its Art Nouveau label will run you about $35 (though some vintages soar in the hundreds).
Its Italian cousin, Prosecco, is popular with our girlfriends and good bottles are less expensive than champagne. We always buy Il Prosecco in multiples because we finish them off so quickly ($13). Don't let the bottle cap throw you, this one is delicious!
