Bright and bubbly and full of pink fizz, these Ruby Red Grapefruit Mimosas are the perfect two-ingredient cocktail to lift any celebration. Ready in minutes, they’re ideal for brunch, pool days, or a relaxed get-together with friends. Serve them alongside other light cocktails for a refreshing summer spread.

August is a busy, festive month in our house — back-to-school routines start up again, and it’s also my birthday month. Between the school hustle and the birthday confetti, I’m always looking for simple, celebratory drinks. I also noticed that National Prosecco Day falls in August, so it feels like destiny to toast with these pretty pink cocktails.
What is a Mimosa?
A traditional mimosa mixes citrus juice with sparkling wine. Orange juice is the classic choice, but swapping in different juices creates fun variations. These Ruby Red Grapefruit Mimosas use tart, tangy grapefruit juice for a brighter, slightly bitter edge that pairs beautifully with sparkling wine.
Ingredients
These mimosas are all about big color and bright flavor, yet they’re extremely simple to prepare. You only need two main ingredients (three if you include the optional garnish):
- Ruby red grapefruit juice (chilled)
- Prosecco, champagne, or any sparkling white wine (chilled)
Because the grapefruit juice has strong flavor and color, you don’t need an expensive bottle of sparkling wine. An affordable Prosecco or other sparkling white wine works beautifully.

Step by step
- Combine grapefruit juice and Prosecco in equal parts. That’s it — simple and delicious.
Serving suggestions
For a pretty pitcher presentation, pour chilled ruby red grapefruit juice into a pitcher and add frozen grapefruit slices to keep it cold without watering it down. You can make the frozen slices by slicing half a grapefruit and freezing the slices ahead of time.
Garnish each glass with a grapefruit wedge or add a sprig of rosemary, thyme, or mint for an aromatic touch. Don’t worry if you don’t have champagne flutes — stemless wine glasses or any pretty glassware will work well for a relaxed summer vibe.

These mimosas are visually stunning — the ruby-red hue and lively bubbles make them feel special without fuss.

Variations
If you want to tweak the flavor, add a splash of vodka, grapefruit liqueur, Grand Marnier, or Triple Sec for extra depth. A small splash of cranberry juice also complements the grapefruit and adds color.
