Craving a mimosa but want to mix it up? Check out the easiest twist on this classic cocktail to ring in Christmas morning: the Kombucha Mimosa! There are tons of kombucha flavors you could easily substitute, because, let's face it, it's rare for a flavor profile to clash with Champagne or Prosecco (though we do recommend staying away from GT's MultiGreen). A mimosa is best served with either a brut Champagne or Prosecco. A traditional mimosa is 1/2 wine and 1/2 orange juice, and we did the same with kombucha.
