Blueberry mojitos are a fun summer twist on a refreshing rum cocktail. This traditional Cuban drink gets a decidedly un-authentic fruity take using one of summer's best berries.

Blueberry Mojito Rum Cocktails

A fresh blueberry mojito is delicious and full of summer flavors, like bright mint, sweet blueberries, and tart lime, making this refreshing drink a great way to beat the summer heat.

I love growing mint in my herb garden, and mojitos are a delicious way to use fresh mint. Grab some fresh fruit at the farmers market and you'll be all set to make this twist on a classic mojito recipe.

This blueberry mojito recipe skips the cocktail shaker, opting to combine fresh lime juice and fresh mint leaves directly in a tall glass like a highball glass or Collins glass.

They're also low in alcohol, with white rum being the only liquor included in the cocktail. That makes these blueberry mojitos a great white rum cocktail to sip when you're wanting an afternoon cocktail that isn't super strong.

To keep yourself enjoying mojitos all summer, make batches of cocktail syrups - blueberry for this recipe! - ahead of time and store them in the refrigerator. Fruit syrups will last for 2 weeks.

Classic mojitos are made with simple syrup, which will keep for at least 3 weeks. (Just watch for it to go cloudy, and toss it when that happens!)

Ingredients

White rum - Choose your favorite white rum. Not sure what to use? Bacardi is easy to find and will taste great in your mojitos.
Blueberry simple syrup - You can buy this at the store (look for brands like Monin and Toriani) or better yet make it at home in 10 minutes with 3 ingredients!
Sugar cubes OR white sugar - You just need a little bit of granulated sugar for muddling so use whichever you have on hand.
Mint leaves - Fresh mint is a key ingredient in mojitos.
Fresh limes - Fresh citrus makes a BIG difference, especially in mojitos. You'll need about a quarter of a fresh lime per cocktail.
Fresh blueberries - You need fresh berries here, not frozen blueberries.
Sparkling water or club soda - Either one will be delicious, just pick your favorite fizzy water.

How to Make a Blueberry Mojito Cocktail

Place 3-4 mint leaves, 4-5 blueberries, and 1-2 slices of lime in a glass.

Top with the sugar.

Using a muddler or wooden spoon, gently crush everything together in the bottom of the glass mashing until the sugar starts to dissolve into the fruit and the mint oils have been released. (You'll smell it!)

Add blueberry simple syrup and white rum, plus enough ice cubes to fill the glass.

Top with sparkling water or soda water.

Give your drink a gentle stir to mix everything together.

Garnish with a mint sprig, some extra blueberries, and/or a lime slice.

Sip and enjoy!

Recipe Tips

Make the syrup several hours in advance so it has time to chill. Warm or even room temperature cocktail syrup will cause your ice to melt faster, watering down your drink. Make your syrup 4 to 24 hours ahead of time. I often make mine first thing in the morning so it's ready for happy hour.
You can make your syrup with frozen blueberries, but if you can't get fresh berries for muddling in the drink, just leave them out.
Use fresh lime juice for this drink, not bottled. It makes a difference!

Making Homemade Blueberry Syrup

Homemade blueberry syrup is easier to make than you may think and only takes 3 ingredients! Get the recipe, instructions, and syrup-making tips over on my Blueberry Simple Syrup page.

Can I use frozen blueberries?

Yes! For the syrup, add them into the pot frozen and just increase the cook time by 3-4 minutes. For the cocktail, thaw the blueberries before adding them to your glass.

What can I use instead of fresh mint?

There's no substitute for fresh mint. You must have it to make a mojito. It grows easily in a pot or can be found in the produce section of most major grocery stores.

What kind of rum should I use?

I use Bacardi brand white rum in my mojitos. It's a clear rum with a more subtle flavor than its dark rum cousins.
