Coconut water iced coffee is my go-to pick-me-up on hot afternoons when I want something hydrating with a little caffeine punch. The combination of chilled coconut water and bold espresso brings a subtle sweetness and gentle tropical twist to classic iced coffee without feeling heavy or overly rich.
I first discovered this recipe while experimenting for a summer brunch. Now it is my favorite way to treat friends when they visit. People are always amazed at how refreshing and different it tastes.
Ingredients
- Freshly brewed espresso or strong coffee: provides the bold coffee flavor. Use a medium or dark roast for the best taste and let it cool fully for a smooth texture.
- Chilled coconut water unsweetened: balances the coffee with a delicate natural sweetness. Select coconut water with no added sugar and taste a small sip first to ensure it is not sour or stale.
- Maple syrup or agave syrup optional: adds customizable sweetness. Use pure maple or agave for the cleanest flavor and start with a small amount.
- Ice cubes: keep your drink cold and refreshing. Use filtered water for the clearest ice.
- Toasted coconut flakes or coffee beans for garnish: bring texture and add a tropical coffee aroma. Toast coconut flakes in a dry pan until golden if you want a little something special.
Step-by-Step Instructions
- Fill the Glasses:
- Start by adding plenty of ice cubes into two tall glasses. The more ice the colder and more refreshing your finished drink will be.
- Pour the Coconut Water:
- Carefully pour two hundred ml of well-chilled coconut water into each glass. Aim for unsweetened coconut water as it blends best with the coffee.
- Add the Espresso or Coffee:
- Pour one shot or about thirty ml of cooled espresso into each glass. Or use sixty ml of cooled strong brewed coffee for a milder flavor. Espresso adds intensity while brewed coffee is more subtle.
- Mix to Combine:
- Stir slowly and gently with a long spoon to blend the coconut water and coffee. Take care not to splash or over-stir so the drink stays layered and nicely chilled.
- Sweeten to Taste:
- If you want your coffee a little sweeter add maple or agave syrup. Stir again until the syrup dissolves completely so there are no pockets of unmixed sweetener at the bottom.
- Garnish and Serve:
- Top with toasted coconut flakes for crunch or a coffee bean for fragrance. Serve right away while the drink is cold and the flavors are fresh.

My favorite part is the toasted coconut garnish. When I serve this for brunch my family loves to nibble the flakes between sips and it always makes the coffee feel more festive.
Storage Tips
To keep this drink at its best prepare just what you will drink right away. Mixing ahead causes the ice to melt and waters down the flavors. If you must store it mix the coffee and coconut water ahead and keep refrigerated without ice. Add ice and garnish right before serving to keep it lively.
