Notes
Tips: For a more festive touch, you can add a splash of Grand Marnier or Cointreau to each mimosa.You can also use grapefruit juice or cranberry juice in place of orange juice.If you're serving a crowd, you can make a large batch of mimosas by combining the sparkling wine and orange juice in a pitcher.To keep the mimosas cold, you can chill the pitcher in the refrigerator or freezer.
