If you want a summertime cocktail that’s refreshing, fruity, and not too sweet, a Grapefruit Gin and Tonic is for you! You only need gin, grapefruit juice, tonic water and ice to make this refreshing drink. It may have no frills, but it does have plenty of flavor!

It’s easy to indulge in sugary drinks, especially during the summertime. When you’re looking up cocktail recipes during the months of May-August, they almost all have lots of fruit juices and simple syrups. While I do love sweeter cocktails, it’s nice to also enjoy something on the less sweet side that’s still refreshing and fruity.
That’s where this Grapefruit Gin and Tonic comes in! A plain gin and tonic is tasty, but the addition of grapefruit juice makes it a touch more summery without making it sugary. When you take that first ice cold sip on a hot day or night, it really does hit the spot perfectly. This recipe also calls for just the right amount of gin – it’s noticeable, but not overpowering.
I also love how truly simple this cocktail is. Besides the ice, you really only need three other ingredients to concoct it. During a party, if you’re on drink duty, you don’t want to have to mix in a ton of ingredients. This is a great recipe to stir up in just a few moments, so you can be the best host, but also not miss out on all of the fun!
What You’ll Need:
- Gin – Dry gin is ideal for this recipe. Try to use a good quality gin!
- Grapefruit Juice – Any brand of grapefruit juice works just fine.
- Tonic Water – The distinct bitter flavor of tonic compliments the gin and grapefruit juice in a delicious way. Don’t substitute it with anything else.
- Ice

Common Questions
Can I make a Grapefruit Gin and Tonic sweeter? Yes! I’ve found that the best way to sweeten these cocktails while still keeping them slightly bitter is to use honey. Simple syrup makes them a little bit too sweet.
How should I garnish my Grapefruit Gin and Tonic? Fresh herbs and grapefruit slices compliment this drink perfectly. I like rosemary, but you could opt for thyme, mint, or basil.
