For this variation on a classic Mimosa, I simply substituted grapefruit juice in place of the orange juice. It was a lovely change of pace.
Grapefruit juice (white, pink, or ruby red), chilled*
Champagne or sparkling white wine, chilled
Pour the grapefruit juice into a champagne flute until it is 1/2 full.
Top with the champagne until full.
-- 1 serving
*Note: Use unsweetened grapefruit juice for a tart, natural flavor. For a sweeter and smoother mimosa, use sweetened juice or grapefruit juice cocktail.
