Easy Grapefruit & Rum Cocktail Recipe

Jump to Recipe

It’s peak grapefruit season right now (December to April) so let’s make a delicious Grapefruit Cocktail with some fresh grapefruit juice! These grapefruit rum cocktails are such an easy recipe since all you need is; a grapefruit, lime juice, white rum and club soda.

If you are a big fan of citrus (like me) and want to make a wonderful citrus salad, try this Jicama-Citrus Salad or my favourite Citrus Salad with a Honey Mustard Vinaigrette.

I always like to find effortless ways to elevate everything, and a simple way to do this is to add a splash of bitters or a rosemary sprig, even some fresh mint sprigs are a fabulous addition. If you have more rum selections in your home bar, you can also use an aged rum for extra depth or even coconut rum for a fun twist.

If you love easy Grapefruit cocktails as much as I do, you have to try these Grapefruit Mimosas or this refreshing Grapefruit Martini.

Let’s make some easy grapefruit cocktails…

This recipe makes two grapefruit cocktails. You’ll need one grapefruit for the juice and a second if you want some slices as garnish. Once you squeeze out the juices of the grapefruit using a citrus juicer or press, squeeze the juices of the lime and add with the grapefruit juice. For a smooth cocktail, I prefer to strain the mixture to remove any pulp or seeds from the grapefruit.

Ingredients for this simple Grapefruit and Rum Drink

• 1 grapefruit
• 1 lime
• 2 oz of rum
• soda water
• 1 slice of grapefruit, for garnish
• fresh mint, for garnish

How to Make a Grapefruit Rum Cocktail

1. Strain the mixture and pour the juice into a cocktail shaker.
2. Add two ounces of rum with a handful of ice. Shake for 20 seconds and strain into two tall glasses filled with a cup of ice cubes.
3. Top with soda water and garnish with a slice of grapefruit.

Tips for the best cocktail

You can use a flavoured rum; like Bacardi Grapefruit flavoured rum. You can pretty much play around with any new flavours that would complement the citrus taste of the grapefruit. As for the soda water, I love using the pink grapefruit flavour, but you can play around with other tropical fruit flavours. A great pairing would be a raspberry since the combination of citrus raspberry flavours is one of my favourites.

If you don’t want to squeeze your own grapefruit juice, swap for pink lemonade or bottled grapefruit juice.

If you like your cocktails sweeter, you can add a little simple syrup. Find the recipe and even some simple substitutions here.
