Full Ingredients

For the Cucumber Mint Base

• 3 large English cucumbers, chilled, roughly chopped, about 2 pounds total
• 1 cup cold filtered water
• 1/2 cup fresh mint leaves, lightly packed, tender stems okay
• 1/2 cup freshly squeezed lime juice, from about 4 medium limes
• 3 tablespoons agave nectar or simple syrup
• 1/4 teaspoon fine sea salt

For Serving

• 2 cups chilled soda water, divided
• 2 cups ice, plus more as needed for the glasses
• 4 thin cucumber ribbons or 8 thin cucumber slices, for garnish
• 4 fresh mint sprigs, for garnish
• 4 lime wheels or wedges, for garnish

Optional Add-Ins

• 1/2 teaspoon finely grated fresh ginger, for a gentle zing
• 1 to 2 teaspoons extra agave nectar, if your limes are especially tart
• 1/4 cup coconut water, replacing 1/4 cup of the filtered water, for a softer tropical note

Step-by-Step Instructions

Step 1: Chill the glasses and gather your tools

For the crispest, most refreshing drink, place 4 tall glasses in the freezer for 10 minutes before serving. You will need a blender, a fine-mesh sieve, a large measuring cup or pitcher, a spoon or silicone spatula, and a citrus juicer if you have one. Make sure the soda water is fully chilled before you start, because cold soda water keeps the drink bright and bubbly without melting the ice too quickly.

Step 2: Prepare the cucumbers, mint, and lime

Rinse the cucumbers and mint well under cool running water. Because English cucumbers have thin, mild skins, you do not need to peel them; the skin adds a fresh green color and subtle flavor. Roughly chop the cucumbers into 1-inch pieces so they blend easily. Pick the mint leaves from any tough stems, then juice the limes until you have exactly 1/2 cup fresh lime juice.

Step 3: Blend the cucumber mint base

Add the chopped cucumbers, 1 cup cold filtered water, 1/2 cup lightly packed mint leaves, 1/2 cup lime juice, 3 tablespoons agave nectar, and 1/4 teaspoon fine sea salt to the blender. Blend on high speed for 45 to 60 seconds, or until the mixture is very smooth and the mint is finely dispersed. The salt should not make the drink taste salty; it simply sharpens the cucumber and lime flavors.

Step 4: Strain for a smooth, polished texture

Set a fine-mesh sieve over a large measuring cup or pitcher. Pour the blended mixture into the sieve and let it drain, stirring and pressing gently with a spoon or spatula to extract the juice. Avoid pressing too hard at the end, which can push excess pulp through and make the drink cloudy or slightly bitter. You should have about 3 cups of vivid green cucumber-mint juice.

Step 5: Taste and balance the flavor

Taste the strained base before adding soda water. It should taste slightly more intense than the final drink because the soda water and ice will mellow it. If it tastes too tart, stir in 1 to 2 teaspoons more agave nectar. If it tastes too sweet or flat, add 1 to 2 teaspoons more fresh lime juice. If it needs more freshness, slap 4 to 6 extra mint leaves between your palms, stir them into the base for 2 minutes, then remove them before serving.

Step 6: Build the drinks over ice

Fill each chilled glass about two-thirds full with ice. Divide the cucumber-mint base evenly among the glasses, using about 3/4 cup base per drink. The ice should lift the drink visually and keep every sip cold, so do not be shy with it.

Step 7: Add soda water and stir gently

Top each glass with 1/2 cup chilled soda water. Use a long spoon to stir each drink just 2 or 3 times, enough to combine without knocking out the bubbles. The finished refresher should be pale green, lightly sparkling, and fragrant with mint and lime.

Step 8: Garnish and serve right away

Finish each glass with a cucumber ribbon or a few thin cucumber slices, a fresh mint sprig, and a lime wheel or wedge. For a more polished presentation, tuck the cucumber ribbon along the inside of the glass before adding ice. Serve immediately while the soda water is lively and the drink is icy cold.

Pro Tips

• Use chilled cucumbers: Starting with cold cucumbers gives the drink a cleaner, more refreshing finish and reduces the need for extra ice.
• Do not over-muddle the mint: Blending briefly is enough. Aggressive crushing can release bitter notes, especially from older mint stems.
• Strain carefully: A fine-mesh sieve gives the drink a smooth, sophisticated texture. For an ultra-clear mocktail style, strain a second time through cheesecloth.
• Add bubbles last: Soda water should always be added right before serving so the drink stays sparkling.
• Balance before serving: Limes vary in acidity. Taste the base and adjust sweetness or lime juice before pouring it over ice.

Variations

• Ginger Cucumber Mint Refresher: Blend 1/2 teaspoon finely grated fresh ginger with the cucumber base for a brighter, slightly spicy finish.
• Coconut Cucumber Cooler: Replace 1/2 cup of the filtered water with 1/2 cup chilled coconut water for a rounder, lightly tropical flavor.
• Spa-Style Herb Refresher: Swap half of the mint for fresh basil for a more aromatic, garden-inspired drink.

Storage & Make-Ahead

The cucumber-mint base can be made up to 24 hours ahead. Store it in a sealed glass jar or pitcher in the refrigerator at 40 degrees F or below, and stir well before using because natural separation will occur. Do not add the soda water until just before serving, or the drink will lose its fizz. Once mixed with soda water, the refresher is best enjoyed within 15 minutes. Leftover strained cucumber base can also be poured into ice cube trays and frozen for up to 1 month; use the cubes to chill future drinks without diluting them.
