Chilled Watermelon Mint Spritz Mocktail Recipe

This watermelon mint spritz mocktail combines fresh watermelon juice with mint, a little lime juice, and sparkling water. It’s a fruity alcohol-free drink with a light fizz, ready to make in about 10 minutes.

Make a pitcher for four servings and taste before adding sweetener. A ripe watermelon may give you all the sweetness you need.

Ingredients

Makes: 4 servings

Preparation time: About 10 minutes

  • 4 cups seedless watermelon, cubed
  • ¼ cup loosely packed fresh mint leaves, rinsed
  • 1 tablespoon fresh lime juice
  • 2 cups chilled plain sparkling water
  • Plain simple syrup or agave syrup, optional and to taste
  • Ice cubes
  • Extra mint sprigs and small watermelon wedges for garnish, optional

How to Make Your Watermelon Mint Spritz Mocktail

  1. Blend the watermelon. Put the watermelon cubes into a blender and blend until smooth. Work in batches if needed.
  2. Strain the juice. Pour the blended watermelon through a fine-mesh strainer into a large pitcher. Use the back of a spoon to help the juice through, then discard the remaining pulp.
  3. Gently crush the mint. Put the mint leaves and lime juice into a small bowl. Press gently a few times with a muddler or the back of a wooden spoon to release the mint’s aroma. Avoid grinding or shredding the leaves.
  4. Mix and taste. Stir the mint and lime mixture into the watermelon juice. Add a little simple syrup or agave syrup if needed, starting with one teaspoon and tasting before adding more.
  5. Add the sparkling water. Just before serving, pour the chilled sparkling water into the pitcher and stir gently.
  6. Serve over ice. Divide between four glasses filled with ice. Add a mint sprig or small watermelon wedge if you like, and serve immediately.

Adjust It to Your Taste

Prefer less sweetness? Leave out the syrup and let the watermelon provide the sweetness.

Want a sharper finish? Add extra lime juice a teaspoon at a time, tasting as you go.

Prefer a lighter drink? Add a little more chilled sparkling water to each glass.

Like more fruit texture? Skip straining the blended watermelon. The drink will be thicker and may need a gentle stir as it stands.

Prefer no mint leaves in your glass? Let the gently crushed mint sit in the watermelon and lime mixture for about five minutes, then strain it out before adding the sparkling water.

Keeping it simple? Skip the garnishes. The watermelon, mint, and lime flavors are there whether you decorate the glasses or not.

Making It Ahead

Blend and strain the watermelon ahead of time. Keep the juice covered in the refrigerator and use it the next day.

Add the mint and lime closer to serving for a fresher flavor. Watermelon juice may separate as it sits, so stir it before mixing.

Add sparkling water, ice, and garnishes just before serving to keep the bubbles fresh and avoid dilution from melting ice.

Frequently Asked Questions

Do I have to strain the watermelon?

No. Straining makes a smoother, lighter drink. Leaving the pulp in gives it more texture, so choose whichever you prefer.

Can I use frozen watermelon?

Yes. Thaw it in the refrigerator before blending for a juice-based spritz. Blending it while frozen will make a slushier drink.

Can I use bottled watermelon juice?

Yes. Use plain watermelon juice and check whether it contains added sugar. Four cups of watermelon cubes won’t necessarily produce four cups of strained juice, so start with about two cups of bottled juice and adjust the balance to taste.

Can I use bottled lime juice?

Yes. Start with one tablespoon, then taste before adding more. Fresh lime juice gives a fresher citrus flavor, but bottled juice is convenient.

Can I use honey instead of syrup?

Yes, but honey can be difficult to mix into cold juice. Dissolve a small amount in a little warm water, let it cool, then stir it into the watermelon mixture.

Why has my watermelon juice separated?

Fresh watermelon juice can separate as it stands. Stir the juice before adding sparkling water, then give the finished drink a gentle stir if needed.
