If you’re after something crisp, citrusy, and refreshingly easy to sip, the Cointreau Cooler might just become your new favorite. With its bright orange notes, a splash of lime, and a fizzy finish, it’s the kind of drink that instantly lifts your mood-especially on warm afternoons. I’ve made this drink countless times for backyard get-togethers, and it always hits the spot. Here’s how you can make one at home, with a few tips to help you get it just right.

Cointreau Cooler
What You’ll Need
Prep time: 5 minutes
Serves: 1
Glass: Highball or Collins glass
Ingredients
– Cointreau: 1.5 oz (45 ml) – a smooth orange liqueur with a sweet, slightly bitter citrus flavor
– Fresh lime juice: 0.5 oz (15 ml) – adds a zippy, tart balance
– Soda water: Enough to top up (about 3-4 oz / 90-120 ml)
– Ice cubes: Enough to fill your glass
– Fresh mint leaves: A few, for garnish
– Orange slice: For garnish
Method
- In a small shaker or mixing glass, combine 1.5 oz Cointreau and 0.5 oz fresh lime juice.
- Fill a highball or Collins glass with ice. Make sure your glass is chilled for the best experience-just pop it in the freezer for a few minutes before you start.
- Strain the Cointreau-lime mixture over the ice.
- Top it off with chilled soda water. Start with 3 oz (90 ml), then add more if you like it lighter.
- Give it a gentle stir, just enough to mix everything without losing the fizz.
- Garnish with a sprig of mint and a slice of orange. For a pop of color, you can even toss in a few fresh berries.
Tips for a Perfect Cooler
- Use fresh lime juice-bottled just doesn’t have the same bright, clean flavor.
- Don’t skip the garnish. The mint adds a burst of aroma with every sip, and the orange slice makes it feel just a little fancy.
- Play with the bubbles. Add more soda for a lighter drink, or less for a stronger citrus kick.
Make-Ahead Notes
You can mix the Cointreau and lime juice ahead of time and store it in the fridge for up to 24 hours. Just wait to add the soda water until you’re ready to serve-this keeps it nice and fizzy.
Ingredient Swaps & Variations
Sometimes you’re missing an ingredient or just want to switch things up. Here are a few easy changes:
- No Cointreau? Try Grand Marnier for a richer, slightly deeper orange flavor.
- Want a sugar-free twist? Use a naturally flavored sparkling water and reduce the Cointreau by 0.5 oz (15 ml).
- Feeling adventurous? Add a splash of cranberry juice for a festive color and a little tartness.
Fun Variations
Spicy Cointreau Cooler
– Add a thin slice of jalapeño to your shaker.
– Muddle it lightly with the lime juice before adding Cointreau.
– Strain carefully to avoid too much heat-just a hint goes a long way.
Berry Cointreau Cooler
– Toss a few raspberries or blackberries into your shaker.
– Muddle with lime juice, then follow the rest of the recipe.
– Strain into your glass and garnish with a berry skewer.
Tropical Cointreau Cooler
– Add 0.5 oz (15 ml) of coconut water for a beachy twist.
– Garnish with a pineapple wedge or toasted coconut rim.
Non-Alcoholic Version
– Swap Cointreau for 1 oz (30 ml) orange juice and a splash of lemon-lime soda.
– Garnish with mint and orange for the same refreshing vibe.
Storage & Leftovers
This drink is best enjoyed fresh, but you can prep a small batch of the base (Cointreau + lime juice) and keep it chilled in an airtight container for a day. Just add soda water when you’re ready to serve.
Serving Suggestions
The Cointreau Cooler pairs beautifully with light, flavorful dishes. Here are a few of my go-to combos:
Grilled Chicken
The citrus in the drink cuts through smoky grilled flavors, keeping your palate refreshed.
Seafood Salad
Especially those with lemon or orange vinaigrettes-this pairing is a citrus lover’s dream.
Vanilla Desserts
Think panna cotta, vanilla bean ice cream, or a simple sponge cake. The cooler’s brightness brings out the sweetness without overpowering it.
This has been my go-to cocktail for summer nights on the porch-easy to make, easy to love.
FAQ
Can I use bottled lime juice?
You can, but fresh lime juice really makes the drink pop. It’s worth the squeeze.
How can I make it more festive?
Try a sugar rim, add a splash of cranberry juice, or garnish with edible flowers.
Can I batch this for a party?
Absolutely. Mix a larger batch of Cointreau and lime juice in advance. Keep it chilled and let guests top their glasses with soda water and ice.
Is it only a summer drink?
Not at all. The citrusy brightness actually makes it great for winter too-it’s like a little sunshine in a glass.
What’s the best garnish?
A sprig of mint and an orange slice are classic. For something different, try fresh thyme or a twist of lime peel.
Can I use tonic water instead of soda?
Yes! Tonic gives it a slightly bitter edge, which balances the sweetness nicely.
