Ingredients

45 ml (1½ oz) premium vodka
15 ml (½ oz) blue curaçao liqueur
120 ml (4 oz) lemon‑lime soda (e.g., Sprite, 7‑Up, or a club soda blend)
Ice cubes (enough to fill a highball glass)
Optional garnish: lemon wheel or a sprig of fresh mint

How to Make the Blue Lagoon Cocktail (8‑12 Easy Steps)

Gather your tools. You’ll need a highball glass, a bar spoon (or any long spoon), a jigger or measuring spoons, and a handful of ice.
Chill the glass. Place the highball glass in the freezer for 10‑15 seconds or fill it with ice water while you prepare the drink; discard the water before pouring.
Add ice. Fill the chilled glass to the top with fresh ice cubes. This ensures the cocktail stays cold without diluting too quickly.
Measure the vodka. Using a jigger, pour 45 ml (1½ oz) of premium vodka over the ice. Premium vodka provides a clean base that lets the blue curaçao shine.
Pour the blue curaçao. Add 15 ml (½ oz) of blue curaçao liqueur. The vibrant hue is what gives the cocktail its signature “lagoon” appearance.
Top with soda. Slowly pour 120 ml (4 oz) of lemon‑lime soda into the glass, allowing it to cascade over the ice and create a gentle fizz.
Stir gently. Using a bar spoon, give the mixture a quick 2‑second stir to combine flavors without flattening the carbonation.
Garnish (optional). Slide a thin lemon wheel onto the rim or drop a fresh mint sprig into the drink for a pop of aroma and visual contrast.
Serve immediately. The cocktail is best enjoyed while the soda is still lively and the ice is crisp.
Adjust sweetness. If you prefer a sweeter profile, add an extra splash of soda or a dash of simple syrup; taste and modify to your preference.
Scale up for a punch. Multiply each ingredient by the number of servings (e.g., for 10 guests, use 450 ml vodka, 150 ml curaçao, 1.2 L soda) and serve in a large pitcher.
Enjoy responsibly. Remember to sip slowly, hydrate between drinks, and provide non‑alcoholic alternatives for designated drivers.

Pro Tips & Tricks

Use chilled soda. Keep your lemon‑lime soda in the refrigerator until the last minute to preserve maximum carbonation.
Choose quality curaçao. A good blue curaçao offers natural orange flavor; cheaper versions can taste overly sweet or artificial.
Ice matters. Use large, clear ice cubes to slow dilution and keep the drink crisp longer.
Pre‑mix for parties. Combine vodka and curaçao in a pitcher ahead of time; add soda just before serving to maintain fizz.
Glassware upgrade. Serve in a sleek highball or a clear hurricane glass for extra visual impact.

Variations & Substitutions

Fruit‑Infused Lagoon

Add 30 ml of fresh pineapple juice or mango puree before topping with soda for a tropical twist. The extra fruit sweetness pairs beautifully with the citrus base.

Herbal Breeze

Muddle a few fresh basil leaves or rosemary sprigs at the bottom of the glass before adding ice. The herbaceous aroma adds depth without overpowering the drink.

Low‑Calorie Lagoon

Swap regular lemon‑lime soda for a diet version or a sparkling water flavored with natural citrus essence. You’ll cut roughly 80 calories per serving.

Non‑Alcoholic “Lagoon”

Replace vodka with 45 ml of coconut water and keep the blue curaçao (or a non‑alcoholic blue syrup). This creates a vibrant mocktail that still delivers the iconic color.

Storage Tips

The Blue Lagoon Cocktail is best enjoyed fresh, but you can prep components ahead of time to streamline service. Store the vodka‑curaçao mixture in an airtight bottle in the refrigerator for up to 5 days; give it a quick shake before using. Lemon‑lime soda should remain sealed and chilled until the moment of serving to retain its fizz. If you’ve made a large batch, keep the mixed alcohol portion separate from the soda and combine only when you’re ready to pour, ensuring each glass retains its lively carbonation.
