Dark Rum Mojito

Most people think of a mojito as a light rum cocktail, but switching to dark rum completely changes the experience. This Dark Rum Mojito keeps the refreshing mint and lime combination everyone loves while adding rich notes of caramel, vanilla, and oak. The result is a cocktail that’s both crisp and full of depth.

The brown sugar cube is another small change that makes a big difference. Instead of plain sweetness, it adds subtle molasses flavor that blends beautifully with the dark rum. Fresh mint keeps the drink bright, sparkling water lightens every sip, and plenty of lime juice balances everything with fresh citrus. I love making this mojito when I want something familiar but a little more interesting than the original. It feels just as refreshing on a hot afternoon, yet the richer rum gives it a cozy character that makes it enjoyable throughout the year.

Ingredients

Simple ingredients are the secret behind every great mojito. Fresh mint, citrus, and quality rum work together to create a balanced cocktail that’s refreshing without being overly sweet.

• 2 oz dark rum
• 1 brown sugar cube
• 1 oz lime juice
• 6 fresh mint leaves
• Sparkling water to top
• Mint sprig and lime wheel for garnish

Dark rum is the star of this recipe, bringing notes of caramel, vanilla, toasted oak, and spice. Brown sugar complements those flavors naturally, creating a richer sweetness than white sugar or simple syrup.

Fresh lime juice adds bright acidity that balances the rum, while mint contributes its signature cooling aroma. Sparkling water lightens the drink and makes it wonderfully refreshing, while the garnish adds fresh fragrance with every sip.

• Goslings Black Seal Rum creates a deeper, fuller bodied cocktail.
• Appleton Estate Signature Blend adds subtle tropical fruit and oak notes.
• Mount Gay Eclipse provides a smooth finish with balanced vanilla flavors.

Equipment and Glassware

This cocktail requires very little equipment, making it perfect for beginners and experienced home bartenders alike.

You’ll need:

• Muddler

• Bar Spoon

A sturdy highball glass provides plenty of room for the ice, sparkling water, and fresh garnishes while allowing the mint aroma to shine.

How to Make It

The Dark Rum Mojito is built directly in the serving glass, making preparation quick and cleanup easy.

1. In a highball glass, add the brown sugar cube and lime juice.
2. Muddle until the sugar dissolves.
3. Add the mint leaves and gently press them to release the oils. Avoid shredding the leaves.
4. Pour in the dark rum and fill the glass with ice.
5. Stir to mix everything well.
6. Top with sparkling water and give it one last gentle stir.
7. Garnish with a mint sprig and lime wheel.

If you’d like a stronger mint aroma, gently clap the garnish between your hands before placing it in the glass.

Storage and Serving Notes

This cocktail is best made fresh because the mint begins to lose its aroma after sitting for too long.

If you’re entertaining, you can prepare the lime juice and brown sugar mixture ahead of time. Add the mint, rum, ice, and sparkling water just before serving to keep the cocktail fresh and bubbly.

Always garnish immediately before serving for the brightest presentation and aroma.
