This raspberry fizz mocktail is light, bubbly and bursting with sweet-tart flavor from ruby red grapefruit juice and raspberry syrup. Enjoy it as a mocktail, or spike it for festive spring and summer sipping!

I’m not much of a cocktail drinker—the dietitian in me chooses plain water most of the time—but I’m always excited when there’s a fun alcohol-free option on the menu. This pretty pink raspberry fizz mocktail recipe, developed by our Test Kitchen, definitely caught my eye. Bubbly club soda makes it feel like a special treat, while grapefruit juice and raspberry syrup deliver just the right balance of sweet-tart flavor.

This fruity drink fits right in at weekend brunch, during summer picnics or for sipping on the patio. It’s also perfect for bridal or baby showers, birthday parties or any celebration where you want a festive sip without alcohol. And if you are in the mood for a cocktail, simply add your spirit of choice for an easy upgrade.

Raspberry Fizz Ingredients

  • Grapefruit juice: This raspberry fizz mocktail is made with ruby red grapefruit juice, which adds a pretty blush color and balanced sweet-tart flavor. Pink grapefruit juice works, too, but skip white grapefruit juice, which is the most bitter of the bunch.
  • Raspberry syrup: You can usually find flavored syrups, like Torani, in the coffee aisle. For more control over ingredients and sweetness, you can easily make your own syrup by mashing fresh raspberries into homemade simple syrup, then straining it through a fine-mesh sieve.
  • Club soda: Chilled club soda adds refreshing fizz and a crisp, slightly salty taste thanks to added minerals. For a more neutral flavor, swap in seltzer or a fruity-flavored sparkling water.
  • Raspberries: Fresh raspberries make a perfect garnish for this mocktail. Drop a few into each glass, thread them onto cocktail picks or freeze them into ice cubes for an extra-pretty presentation.

Directions

Step 1: Mix the fruity elements

In a mixing glass or tumbler, stir together the grapefruit juice and raspberry syrup until well combined. Fill a highball glass with about 1/2 cup of ice cubes, then pour the juice mixture over the ice.

Editor’s Tip: Give the mixture a quick taste before pouring. Add a splash more syrup or juice to adjust the sweetness or tartness to your liking.

Step 2: Add the soda and serve

Top the juice with club soda. If desired, garnish with fresh raspberries. Serve immediately.

Editor’s Tip: Pour the club soda slowly over the juice to create a pretty layered look, or give the drink a stir with a straw if you want it fully mixed.

Raspberry Fizz Variations

  • Replace the citrus: Trade the grapefruit juice for fresh orange juice or pink lemonade for a different citrusy base.
  • Switch up the sparkle: Use plain or flavored sparkling water for a subtle flavor boost, or swap in ginger ale for a sweeter, spicier twist.
  • Use homemade raspberry syrup: Simmer equal parts sugar and water to make a classic simple syrup, then mash in fresh raspberries and strain the mixture through a fine-mesh sieve for an all-natural option.
  • Turn it into a cocktail: Add a shot of gin for a bright, botanical twist, or top with sparkling wine instead of club soda for a festive grown-up sip.
  • Add fresh herbs: Garnish the drink with a sprig of mint or basil for a pop of color and aroma, or muddle the herbs with the raspberry syrup to infuse the drink with garden-fresh flavor.

Can you store a raspberry fizz?

Since this raspberry fizz is made with bubbly club soda, it’s best mixed and enjoyed fresh. Although you can store leftovers in the fridge, the drink will lose its sparkle as it sits.

Can you make a raspberry fizz ahead of time?

This raspberry fizz isn’t make-ahead friendly. It’s best made just before serving for maximum bubbles. If you want to get a head start, mix the grapefruit juice and raspberry syrup in a jar and refrigerate it for a few days. When you’re ready to serve, pour it over ice and top it with fresh club soda.

Raspberry Fizz Tips

What can you use instead of raspberry syrup?

If you don’t have raspberry syrup or prefer to use fresh fruit, muddle a few raspberries in your serving glass, then add a splash of simple syrup, honey or agave to sweeten. This method works with other berries too. Try strawberries, blueberries or blackberries for a slightly different flavor. For a smoother sip, muddle the berries in a jar or a cocktail shaker with your sweetener of choice and grapefruit juice, then strain the mixture into your glass.

What kind of glass should you use for a raspberry fizz mocktail?

A tall glass, like a highball or Collins glass, works best for this raspberry fizz mocktail. The extra height leaves plenty of room for ice and club soda, and it shows off the drink’s pretty layered look. If you don’t have dedicated glassware, a stemless wineglass or even a Mason jar works perfectly for a more casual feel.

Can you make raspberry fizz mocktails for a crowd?

Yes! To make raspberry fizz mocktails for a crowd, mix a larger batch of grapefruit juice and raspberry syrup in a pitcher ahead of time and refrigerate it. When it’s time to serve, pour the fruity mixture over ice and top each glass with fresh club soda.

What can you serve with a raspberry fizz?

This raspberry fizz is light and refreshing, making it a perfect pairing with brunch favorites like a golden quiche or breakfast casserole. Add a basket of flaky scones and a colorful fruit salad for an easy brunch menu. It also works beautifully alongside fresh green salads, tea sandwiches and other finger foods for special occasions like bridal or baby showers.
