Chill your sparkling wine in the refrigerator for at least 30 minutes. The colder, the better!
In a champagne flute, add sparkling wine and pineapple juice.
Top the cocktail off with a splash of lemon-lime soda, to taste.
Garnish with a fresh pineapple wedge, fresh strawberry or lime slice.
Notes
Most mimosa recipes call for a dryer champagne, like a Brut sparkling wine. If you incorporate the lemon-lime soda, I recommend a Brut champagne. If you would like to just use sparkling wine and pineapple juice, try to find a sweeter variety of champagne to use like Prosecco! The pineapple juice can be quite tart!
