Ingredients

- 2 oz white rum
- 1.5 oz rhubarb mint simple syrup
- 1 oz lime juice
- Few sprigs fresh mint

White rum provides a clean base that allows the mint and rhubarb flavors to shine. Rhubarb mint simple syrup contributes sweetness with a subtle tart edge. Fresh lime juice brightens the drink and balances the syrup, while soda water adds a light, bubbly finish.
Fresh mint is essential for this cocktail. Its aroma plays a major role in creating the classic mojito experience.
Suggested Liquor Brands and Substitutions
Choosing a quality white rum helps this cocktail reach its full potential without overpowering the delicate rhubarb and mint flavors.
- Bacardi Superior: Clean and classic for mojitos.
- Flor de Caña Extra Seco: Smooth with subtle complexity.
- Plantation 3 Stars: Richer flavor while remaining balanced.
- Don Q Cristal: Crisp and refreshing.
- Homemade rhubarb syrup: A great substitute if rhubarb mint syrup is unavailable.
- Honey syrup: Can replace simple syrup in homemade variations.
If you can’t find rhubarb mint syrup, combine rhubarb syrup with a few extra mint leaves while muddling to create a similar flavor profile.
Equipment and Glassware
This cocktail requires only a few basic bar tools and is easy to prepare at home.
You’ll need:
A highball glass offers extra room for crushed ice and garnishes, while a rocks glass provides a slightly more compact presentation.
How to Make It
The key to a great mojito is gently releasing the mint oils without shredding the leaves. This creates a cleaner flavor and better appearance.
- Muddle: Place fresh mint in the bottom of a rocks glass and gently muddle to release the oils.
- Build: Fill the glass with crushed ice. Add rhubarb mint syrup, lime juice, and white rum.
- Top: Add a splash of soda water.
- Stir: Use a bar spoon to stir gently, mixing the flavors and chilling the drink evenly.
- Garnish: Top with more mint or a lime wedge for a visual and aromatic finish.
A gentle stir is all you need. Over-stirring can reduce the carbonation from the soda water.
Pro Tips
A few simple techniques can make a big difference in the final cocktail.
- Use fresh mint with bright green leaves.
- Gently muddle the mint rather than crushing it.
- Use freshly squeezed lime juice whenever possible.
- Fill the glass completely with crushed ice.
- Chill your glass before serving.
- Use cold soda water to maintain carbonation.
- Slap the mint garnish between your hands before adding it.
- Serve immediately after building the cocktail.
The aroma from fresh mint is one of the best parts of this drink, so don’t skip the garnish.
Variations
The Rhubarb Mint Mojito can easily be customized depending on your preferences or the ingredients you have available.
- Strawberry Rhubarb Mojito: Add fresh strawberries while muddling.
- Frozen Rhubarb Mojito: Blend the ingredients with ice.
- Raspberry Rhubarb Mojito: Add a handful of raspberries.

Each variation highlights the refreshing qualities of the original while introducing a new flavor element.

Storage and Serving Notes
This cocktail is best enjoyed immediately after preparation. Fresh mint and soda water provide their brightest flavors when served right away.
If entertaining guests, you can prepare the rhubarb mint syrup ahead of time and refrigerate it until needed. Fresh lime juice can also be squeezed several hours in advance.
Wait until serving to muddle the mint and add soda water. This helps preserve freshness and carbonation.
For larger gatherings, prepare a pitcher of the rum, syrup, and lime juice mixture and build individual drinks with mint, ice, and soda water.
