A Captain On Acid is one of those cocktails that’s both fun to make and even more fun to drink. It’s tropical, slightly tart, and has just the right amount of sweetness. The mix of rum, coconut, pineapple, and blackcurrant liqueur gives it a bold, layered look—almost like a sunset in a glass. If you’re looking for a refreshing drink that feels like a mini vacation, this one’s a winner.
Captain On Acid
I’ve made this cocktail countless times for summer gatherings, and it always gets people talking. The flavors are smooth, fruity, and just adventurous enough to keep things interesting. Let’s get started!
Ingredients
You’ll need:
- 1.5 oz (45ml) white rum
- 1 oz (30ml) coconut liqueur
- 2 oz (60ml) pineapple juice
- 0.5 oz (15ml) blackcurrant liqueur
- Splash of fresh lime juice
- Ice
Glass: A highball glass works best, but a mason jar gives it a fun, casual vibe.
How to Make It
- Fill a cocktail shaker with ice. Pour in the rum, coconut liqueur, pineapple juice, and a splash of lime juice.
- Shake well until the mixture is chilled—about 10-15 seconds.
- Strain into a highball glass filled with ice.
- Slowly pour the blackcurrant liqueur over the drink. It’ll sink slightly, creating a beautiful layered effect.
- Garnish with a pineapple slice or a lime wheel. Serve immediately and enjoy!
Tips for the Best Captain On Acid
- Use fresh pineapple juice if possible. It makes a huge difference in flavor compared to bottled juice.
- Pour the blackcurrant liqueur gently so it layers nicely instead of mixing in too fast.
- Balance is key—if you like it more tart, add a little extra lime juice. If you prefer it sweeter, increase the blackcurrant liqueur.
I’ve found that shaking the cocktail with just the right amount of ice helps it chill without watering it down too much. A cold drink with bold flavors is what makes this cocktail so refreshing.
Variations & Substitutions
Want to switch things up? Here are a few ideas:
- Swap the rum: Try dark rum for a richer flavor.
- Go creamier: Use coconut cream instead of coconut liqueur for a smoother texture.
- Make it less sweet: Cut back on the blackcurrant liqueur and add an extra splash of lime juice.
Virgin Captain On Acid
For a non-alcoholic version, replace:
- Rum → coconut water
- Blackcurrant liqueur → blackcurrant syrup
- Coconut liqueur → a splash of coconut milk
Follow the same steps, and you’ll have a refreshing tropical mocktail.
What to Serve with It
This cocktail pairs well with:
- Grilled seafood – The smoky flavors of shrimp or fish balance out the drink’s sweetness.
- Spicy appetizers – Something with a little heat (like spicy wings or jalapeño poppers) works great with the cool, fruity flavors.
- Light fruit desserts – A simple fruit salad or coconut sorbet makes a perfect match.
Make-Ahead & Storage Tips
- You can pre-mix everything except the blackcurrant liqueur and store it in the fridge for a few hours. Just give it a good shake before serving.
- Add the blackcurrant liqueur right before serving to keep the layered look.
- If you have leftovers (unlikely, but just in case), store them in an airtight container in the fridge and give them a quick stir before drinking.
Frequently Asked Questions
Can I use bottled lime juice instead of fresh?
You can, but fresh lime juice gives it a brighter, more natural taste.
Can I make this frozen?
Yes! Blend all the ingredients (except the blackcurrant liqueur) with ice for a slushy version. Add the blackcurrant liqueur on top at the end.
Is this drink vegan?
It should be, but check your blackcurrant liqueur to be sure—it sometimes contains non-vegan ingredients.
How do I make it less sweet?
Use less blackcurrant liqueur and add a little extra lime juice.
