Have you ever taken that first sip of something so refreshingly crisp that you actually sigh with relief? That’s exactly what happens with this Kiwi Cucumber Agua Fresca. It’s the drink you didn’t know you needed until that first cool, vibrant mouthful hits your taste buds on a sweltering day.

Why This Recipe is Awesome

What makes this Kiwi Cucumber Agua Fresca stand out is its perfect balance of sweet tropical kiwi against cool, hydrating cucumber. It’s incredibly simple but tastes like something you’d pay $8 for at a trendy juice bar. Unlike many sweetened beverages, this agua fresca lets the natural flavors of the fruits shine through without drowning them in sugar.
The lime adds just enough brightness to make everything pop, while the subtle hint of mint elevates it from refreshing to downright rejuvenating. The best part? This comes together in minutes but tastes like you spent all day perfecting it.
It’s my go-to for impressing guests at summer gatherings without breaking a sweat (literally and figuratively).
Equipment needed: Blender, fine-mesh strainer, pitcher

Kiwi Cucumber Agua Fresca
Ingredients
- 4 ripe kiwi fruits peeled and quartered
- 1 medium cucumber about 8 inches long, peeled and roughly chopped
- 3-4 tablespoons honey or agave nectar adjust to taste
- Juice of 1 lime
- 8-10 fresh mint leaves plus extra for garnish
- 4 cups cold water divided
- Ice cubes for serving
- Cucumber and kiwi slices for garnish optional
Instructions
- Prepare your fruits by thoroughly washing the cucumber and kiwis. Peel the kiwis and cucumber, then roughly chop them into chunks that will blend easily.
- Combine the kiwi, cucumber, sweetener, lime juice, mint and 2 cups of water in a blender. Blend on high speed for 1-2 minutes until completely smooth with no visible chunks remaining.
- Strain the mixture through a fine-mesh sieve into a pitcher, using the back of a spoon to press and extract as much liquid as possible. This removes pulp and seeds for a smoother texture.
- Add the remaining 2 cups of water to the strained mixture and stir well to combine. Taste and adjust sweetness if needed by adding more honey or agave.
- Chill the agua fresca in the refrigerator for at least 30 minutes before serving for the best flavor development, though you can serve it immediately over ice if you’re in a hurry.
- Serve in tall glasses filled with ice, garnished with fresh mint leaves and thin slices of cucumber and kiwi for an eye-catching presentation.
Notes
- For maximum flavor, choose kiwis that yield slightly to gentle pressure – they should be ripe but not mushy.
- If your kiwis aren’t very sweet, you may need to add a bit more sweetener.
- This agua fresca can be made up to 24 hours in advance and stored in the refrigerator – just stir well before serving as separation is natural.
- For a twist, try adding a splash of sparkling water just before serving for a bubbly version.
- The strained pulp can be saved and added to smoothies or yogurt to reduce waste.

Common Mistakes to Avoid
- Not straining the mixture properly – This results in a pulpy texture rather than the smooth, refreshing consistency that defines a true agua fresca.
- Over-sweetening – The natural sweetness of kiwi should shine through; start with less sweetener and adjust to taste.
- Using unripe kiwis – They’ll be too tart and won’t blend as smoothly as properly ripened fruit.
- Skipping the chilling time – While it’s drinkable immediately, the flavors truly develop and meld when allowed to rest in the refrigerator.
- Not adjusting for tartness – Kiwis vary in sweetness; always taste before serving and adjust the sweetener accordingly.
Alternatives & Substitutions
- Sweetener options: Substitute maple syrup, simple syrup, or stevia for the honey/agave depending on your preference or dietary needs.
- Fruit variations: Swap kiwi for pineapple, strawberries, or watermelon for equally refreshing alternatives that pair well with cucumber.
- Herb alternatives: Replace mint with basil or cilantro for interesting flavor variations.
- For a spa-like twist: Add a 1-inch piece of peeled ginger when blending for a zingy kick.
- Adult version: Add a splash of white rum or vodka for a low-ABV cocktail perfect for summer gatherings.
FAQs
Can I make this agua fresca without a blender?
While a blender yields the best results, you can finely grate the cucumber and mash the kiwi with a fork, then combine with water and sweetener before straining. The texture won’t be as smooth, but the flavor will still be delicious.
How long does this agua fresca stay fresh?
When stored in an airtight container in the refrigerator, it will stay fresh for up to 3 days. Natural separation may occur – just stir before serving.
Is this drink suitable for kids?
Absolutely! Kids typically love the naturally sweet, vibrant flavor. You can adjust the sweetness to their preference, and it’s a wonderful way to get them enjoying fruits they might otherwise avoid.
Can I freeze leftover agua fresca?
Yes! Pour it into ice cube trays for refreshing additions to sparkling water later, or freeze in popsicle molds for a healthy frozen treat on hot days.
Why is my agua fresca foamy after blending?
This is normal due to air incorporation during blending. Let it sit for a few minutes after straining, and the foam will naturally dissipate.
