Notes
Tasting Notes
This fruity mocktail has a bright red color from the watermelon and a sparkly effervescence from the Sprite. The drink looks beautiful in a tall glass with ice cubes and mint leaves as garnish.
The first sip brings a sweet and refreshing burst of watermelon. The natural fruit sugars blend perfectly with the lemon-lime soda, creating a balanced sweetness that isn’t too overpowering.
Sprite adds a crisp fizzy texture that makes each sip light and bubbly. The carbonation enhances the watermelon’s natural freshness.
Fresh mint leaves add a cool, aromatic touch that complements the fruit flavors. The herb’s subtle notes come through in the aftertaste.
The drink has a smooth, medium-bodied texture. Ice keeps it properly chilled and helps maintain the ideal serving temperature between 35-40°F.
Best served:
- In a tall glass
- Over fresh ice
- With a mint sprig garnish
- Within 15 minutes of mixing
This mocktail tastes best when enjoyed right away while the carbonation is at its peak and the watermelon is freshly blended.

Substitute
You can swap out regular Sprite with Sprite Zero for a lower-calorie drink. Using diet lemon-lime soda works just as well.
No watermelon? Fresh cantaloupe or honeydew makes a good stand-in. Frozen melon chunks work too. Just skip the ice cubes since frozen fruit keeps drinks cold.
For a different twist, trade the watermelon juice for strawberry puree. The pink color stays pretty and it pairs nicely with the lime soda.
Quick alternatives:
- Ginger ale instead of Sprite
- Sparkling water + lime juice
- Club soda + melon syrup
- Clear cream soda
- 7-Up or Sierra Mist
Want to make it fancy? Add a splash of coconut water or white grape juice. These choices keep the drink clear while adding extra sweetness.
The mint garnish can be switched with basil leaves or a thin slice of lime. Both add fresh flavor and look nice on top of the drink.
