Why This Non-Alcoholic Grapefruit Mojito Is My Go-To Summer Sip

Let’s be real—summer heat hits different, and sometimes you just need a drink that’s zesty, bubbly, and feels like a little vacation in a glass. Enter my non-alcoholic grapefruit mojito! I whipped this up on a lazy Sunday when I was craving something refreshing but didn’t have rum (or even proper cocktail tools, oops). Spoiler: It still turned out amazing, and now it’s my go-to for backyard hangs and post-work cool-downs.
Full disclosure: I made this with whatever I had lying around—no fancy muddler, no cocktail shaker, just an immersion blender (yes, the one I use for baby food) and a rolling pin. If I can do it, you definitely can. Let’s dive in!
What You’ll Need (No Fancy Tools Required!)
Ingredients
- 1 fresh grapefruit (the juicier, the better—look for one that feels heavy for its size)
- 5-6 fresh mint leaves (don’t overdo it—too much mint can taste like toothpaste!)
- 1 tsp granulated sugar (adjust if your grapefruit is super tart)
- ½ lemon (for juice and a cute garnish)
- Sprite (or any lemon-lime soda—about twice the amount of grapefruit juice, but tweak to taste)
Tools I Used (Again, Super Basic)
- A small bowl (for muddling)
- A rolling pin (my makeshift muddler—genius, right?)
- An immersion blender (or regular blender—even a hand juicer works for grapefruit)
- A tall glass (the bigger, the more room for fizz!)
Step-by-Step: How to Make This Refreshing Drink
Okay, let’s get mixing! I took photos of every step so you can follow along—no guesswork here.
Prep the Grapefruit

First, peel your grapefruit and set the flesh aside. I like to remove as much pith as possible because it can add a bitter aftertaste. Trust me on this—your drink will thank you.
Muddle the Mint (The Fun Part!)

Grab 5-6 mint leaves. Fresh is key here—dried mint just won’t give that bright, herby flavor. Tear them a little first to release the oils (pro tip I learned from TikTok!).

Add the mint leaves to a small bowl with 1 tsp of sugar. The sugar helps break down the mint and release its flavor—way better than just using water.

Now, grab your rolling pin (or a muddler if you’re fancy) and gently mash the mint and sugar together. Don’t go crazy—you just want to bruise the mint, not turn it into a paste. If you see a little green liquid, you’re doing it right!
Add the Lemon (Zest + Zing)

Cut a thin, round slice of lemon from the ½ lemon—this is for garnish later. Try to make it a clean slice so it looks pretty on the edge of your glass.

Squeeze the rest of the ½ lemon into the muddled mint-sugar mix. I like to use my hands to squeeze (messy, but effective) to get every last drop of juice out. Pro tip: If you don’t want lemon seeds in your drink, strain the juice first!
Make the Grapefruit Juice

Here’s where my baby food blender comes in! Toss the peeled grapefruit flesh into the blender and blend until it’s smooth. If you don’t have a blender, you can use a hand juicer—just make sure to strain out any pulp if you prefer a smoother drink. I left a little pulp in for texture, but that’s totally up to you.

Pour the grapefruit juice into a cup and set it aside. Now, grab your Sprite—you’ll want about twice as much Sprite as grapefruit juice. For example, if you have ½ cup of grapefruit juice, use 1 cup of Sprite. But feel free to adjust: more Sprite = more fizz, less Sprite = more intense grapefruit flavor.
Put It All Together (And Garnish Like a Pro!)

Take your tall glass and pour the muddled mint-lemon-sugar mix into the bottom. Then add the grapefruit juice—stir it gently with a spoon to combine.

Now for the fun part: slowly pour the Sprite over the top. The fizz will bubble up, so don’t pour too fast! If you have ice (I didn’t, sadly), add a handful here—it makes the drink extra refreshing.
Finally, take that lemon slice you cut earlier and stick it on the edge of the glass. You can also add a mint leaf on top for a little extra flair. Ta-da! Your non-alcoholic grapefruit mojito is ready to sip.
My Pro Tips for Making This Even Better
- Add ice! I skipped it because I was out, but ice makes this drink 10x more refreshing. Crushed ice is even better—it feels like a slushy.
- Swap Sprite for soda water if you don’t like sweet drinks. The grapefruit and lemon will still give it plenty of flavor, and soda water adds fizz without the sugar.
- Make it alcoholic: If you do have rum, add 1-2 oz of white rum to the mix. Just stir it in with the grapefruit juice before adding the Sprite.
- Double the recipe: This makes one drink, but it’s easy to scale up for a crowd. Just multiply all the ingredients by how many people you’re serving.
