If you’re looking for a cocktail that’s like a little Caribbean vacation in a glass, the Mabi Cocktail is it. It’s bright, refreshing, and full of tropical flavor, with roots that go way back to island traditions. I thought I’d share one of my favorite after-dinner cocktails — it’s simple to make, easy to love, and perfect for warm evenings when you just want to kick back and relax.

Mabi Cocktail
Ingredients
What you’ll need:
– 2 oz (60 ml) white rum
– 1 oz (30 ml) Mabi concentrate (*see tip below*)
– 0.5 oz (15 ml) freshly squeezed lime juice
– 0.5 oz (15 ml) simple syrup
– Soda water, to top off
– Ice cubes
– Lime wheel or mint sprig, for garnish
Prep time: 5 minutes
Servings: 1 cocktail
*Glassware:* A highball glass works best, but a mason jar adds a fun, rustic touch.
Method
- Fill a highball glass about three-quarters full with ice cubes.
- Pour in the rum, Mabi concentrate, lime juice, and simple syrup.
- Give it a gentle stir to blend everything together.
- Top off with soda water. Stir again lightly — just enough to mix without losing the bubbles.
- Garnish with a lime wheel or a fresh mint sprig, and serve right away.
Helpful Tips
– Chill your glass beforehand for an extra refreshing sip.
– Always use freshly squeezed lime juice — the bottled stuff just doesn’t have the same zing.
– If you can’t find Mabi concentrate, you can make a quick substitute by infusing simple syrup with tropical fruits like guava or passionfruit. It won’t be exactly the same, but it’ll still taste amazing!
Make-Ahead Notes
You can mix the rum, Mabi concentrate, lime juice, and simple syrup ahead of time and keep it in the fridge for up to a day. Just add ice and soda water when you’re ready to serve.
Storage
If you somehow have leftover mixed base (without soda water), store it in a sealed container in the fridge for up to 24 hours. Once soda water is added, it’s best to drink it fresh — the fizz fades quickly.
What is Mabi?
Mabi (sometimes spelled Mauby) is a traditional Caribbean drink made from the bark of the Mabi tree. It’s lightly fermented, a little sweet, a little bitter, and super refreshing. The concentrate is a syrupy version used for cocktails and mocktails. It’s packed with flavor and brings a unique, earthy sweetness to the drink.
What it Tastes Like
The Mabi Cocktail hits you with a bright, citrusy punch from the lime, followed by the sweet, slightly earthy depth of the Mabi, and a crisp, fizzy finish from the soda water. That little hint of bitterness from the Mabi keeps it from being too sweet. Every sip feels like a cool breeze on a hot day — I’ve made this drink countless times for summer cookouts, and it’s always the first to disappear!
Food Pairings
Grilled seafood: Think shrimp skewers or a smoky grilled snapper — the cocktail’s citrus notes make everything pop.
Spicy appetizers: Jalapeño poppers, spicy wings, or even jerk chicken sliders go great. The Mabi Cocktail cools the heat perfectly.
Tropical salads: A mango, avocado, and shrimp salad with a light vinaigrette would be a dreamy match.
Recipe Variations
Want to mix things up? Here are a few fun twists:
Spicy Mabi Cocktail
– Muddle a thin slice of jalapeño with the lime juice before mixing.
– Follow the rest of the recipe as usual.
– Adds a gentle heat that plays nicely with the sweetness!
Mabi Mojito Twist
– Muddle a few fresh mint leaves with the lime juice and simple syrup.
– Swap soda water for sparkling water if you like.
– The mint makes it extra refreshing.
Non-Alcoholic Mabi Fizz
– Skip the rum altogether.
– Double the Mabi concentrate and top with sparkling water.
– Perfect for anyone skipping the booze but still craving those tropical vibes.
Customizing Your Mabi Cocktail
– Rum choice: White rum keeps it light and crisp, but dark or spiced rum gives it a deeper, richer flavor.
– Sweetness level: If you prefer less sweetness, cut back on the simple syrup or swap it for honey.
– Fizzy twist: Try ginger beer instead of soda water for a spicy kick.
Common Questions
Can I make it without alcohol?
Absolutely! Just skip the rum and add a little extra soda or even coconut water for a tropical twist.
Is it sweet?
Yes, but the lime juice and soda water keep it from being syrupy. It’s nicely balanced — not cloying.
What if I can’t find Mabi concentrate?
Tropical fruit-infused syrups are a good backup, but if you can find Mabi, it’s worth it for that unique flavor.
Do I have to use white rum?
Nope. Feel free to play around with dark or spiced rums. Each one brings a different character to the drink.
Can I add anything else?
Sure! A sprinkle of nutmeg or a dash of bitters can add even more depth.
How can I make it a little healthier?
Use a natural sweetener like agave or honey, and check that your Mabi concentrate doesn’t have added preservatives.
