Full Ingredients

For the Simple Syrup

• 1/4 cup granulated sugar, 50 grams
• 1/4 cup water, 60 milliliters

For the Golden Kiwi Lemon Base

• 4 medium ripe golden kiwis, peeled and chopped, about 320 grams peeled fruit
• 1/2 cup freshly squeezed lemon juice, 120 milliliters, from 3 to 4 medium lemons
• 1 teaspoon finely grated lemon zest, optional but recommended for extra brightness
• 1/16 teaspoon fine sea salt

To Finish and Serve

• 3 cups chilled plain sparkling water, 720 milliliters, ideally 38 to 40 degrees F
• 2 cups ice cubes, about 280 grams
• 4 thin lemon wheels, for garnish
• 4 thin golden kiwi slices, for garnish
• 4 small fresh mint sprigs, for garnish

Step-by-Step Instructions

Step 1: Make the simple syrup

Combine the granulated sugar and water in a small saucepan. Set the pan over medium heat and warm the mixture until it reaches a gentle simmer, about 200 degrees F, stirring often. Cook for 2 to 3 minutes, just until the sugar has fully dissolved and the syrup looks clear. Remove from the heat and let it cool for 10 to 12 minutes, until it is no warmer than room temperature. Warm syrup can melt the ice too quickly and make the sparkling water go flat faster.

Step 2: Prepare the kiwi and lemon

Peel the golden kiwis and chop them into rough 1-inch pieces. If using lemon zest, zest 1 lemon before juicing it; it is much easier to zest a whole lemon than a squeezed one. Juice 3 to 4 lemons until you have exactly 1/2 cup of fresh lemon juice. Strain out any large seeds, but do not worry about a little pulp because it blends nicely into the cooler.

Step 3: Blend the golden kiwi lemon base

Add the chopped golden kiwis, fresh lemon juice, lemon zest, cooled simple syrup, and fine sea salt to a blender. Blend on medium-high speed for 20 to 30 seconds, until the mixture is smooth and sunny yellow-green. Try not to blend much longer than 30 seconds; kiwi seeds are tiny, but over-blending can make them taste slightly bitter.

Step 4: Strain and chill the base

For a polished, sippable cooler, pour the blended mixture through a fine-mesh sieve into a 1-quart pitcher, pressing gently with a spoon to help the liquid pass through. If you prefer a thicker, more fruit-forward drink, you can skip straining. Chill the kiwi-lemon base in the refrigerator or freezer for 10 minutes, aiming for about 40 degrees F before mixing with the sparkling water.

Step 5: Fill the glasses

Place 4 tall 12-ounce glasses on your work surface. Add 1/2 cup ice cubes to each glass. Divide the chilled kiwi-lemon base evenly among the glasses, using about 1/2 cup per glass. If your kiwis were especially juicy and you have a little extra base, simply divide it equally so every drink has the same flavor.

Step 6: Add the sparkle

Slowly pour 3/4 cup chilled sparkling water into each glass. Pour down the inside of the glass if possible to help preserve the bubbles. Stir each drink gently 1 to 2 times with a long spoon, just enough to combine the kiwi-lemon base with the sparkling water without knocking out too much carbonation.

Step 7: Garnish and serve

Garnish each cooler with a lemon wheel, a thin golden kiwi slice, and a small sprig of fresh mint. Serve immediately while the drink is very cold, fizzy, and bright. The best serving temperature is about 38 to 45 degrees F.

Pro Tips

• Use ripe golden kiwis: A ripe golden kiwi should give slightly when pressed, similar to a ripe peach. Firm kiwis will taste more tart and less tropical.
• Chill everything: Cold sparkling water, chilled glasses, and a chilled kiwi-lemon base make the drink more refreshing and help the bubbles last longer.
• Adjust to taste: If the cooler tastes too tart, stir in 1 to 2 teaspoons extra simple syrup per glass. If it tastes too sweet, add 1 to 2 teaspoons extra lemon juice per glass.
• Strain for elegance: Straining creates a smoother, more refined beverage. Leaving it unstrained gives the drink a more rustic, pulpy fruit texture.
• Stir gently: Sparkling water loses its fizz with vigorous stirring, so use a light hand after adding the bubbles.

Variations

• Ginger Golden Kiwi Lemon Cooler: Add 1 teaspoon freshly grated ginger to the blender with the kiwi, or replace 1 cup of the plain sparkling water with chilled ginger sparkling water.
• Mint-Basil Kiwi Cooler: Blend 4 fresh mint leaves and 4 fresh basil leaves into the kiwi-lemon base for a garden-fresh herbal note.
• Coconut Tropical Cooler: Replace 1 cup of the sparkling water with 1 cup chilled coconut water, then finish with 2 cups sparkling water for a softer, more tropical drink.

Storage & Make-Ahead

The kiwi-lemon base can be made up to 24 hours ahead. Store it in an airtight jar or covered pitcher in the refrigerator at 40 degrees F or below, and stir well before using because natural fruit pulp may settle. Do not add the sparkling water until just before serving, or the cooler will lose its fizz. If you want to prep even further ahead, freeze the kiwi-lemon base in ice cube trays for up to 1 month; add 3 to 4 cubes to a glass and top with chilled sparkling water when ready to serve.
