Ingredients

1/4 cup fresh grapefruit juice about 1/2 grapefruit

1/2 cup soda water chilled
1 tablespoon dried culinary lavender
1/4 cup granulated sugar
1/4 cup water
Ice cubes
Grapefruit slices for garnish
Fresh lavender sprig for garnish, optional

Instructions

Add sugar, water, and dried lavender to a small saucepan.
Heat over low, stir until sugar dissolves. Simmer for 3-4 minutes.

Remove from heat. Let cool for 10 minutes, then strain out lavender.
Juice the grapefruit until you have 1/4 cup.
Fill a tall glass with ice cubes.

Pour in fresh grapefruit juice.
Add 2 tablespoons of the lavender syrup (or to taste).
Top with soda water and stir gently with a spoon.

Garnish with a grapefruit slice and a lavender sprig if you like.

Notes

I always use dried culinary lavender, not the ornamental kind, to make sure it’s safe. I strain the syrup well to keep my drink smooth.

If the mocktail is too sweet, I use less syrup or more soda water. For a stronger floral note, I let the syrup steep a bit longer before straining.

Fresh grapefruit juice tastes best, but bottled juice can work in a pinch. The mocktail looks way more appealing with a slice of grapefruit on the rim or a bit of lavender on top.

For less sugar, I sometimes cut the syrup amount in half and add extra soda. I keep extra syrup in a jar in the fridge for up to a week, just in case I want to make another round.

Tasting Notes

When I first taste the Lavender Grapefruit Soda Mocktail, I notice a refreshing balance of flavors. The tartness of grapefruit stands out right away, but it’s softened by the floral notes of lavender.

The drink smells clean and bright. I can pick up a light citrus aroma with a gentle hint of herbs from the lavender syrup.

I find that the mocktail isn’t too sweet. The slight bitterness from the grapefruit helps keep it from being overpowering.

I get a slight tanginess, which makes it feel especially refreshing on a warm day. Here are the main flavors I notice:

Grapefruit juice: tart, juicy, a little bitter
Lavender syrup: floral, light, and slightly sweet
Club soda: adds fizz without extra flavor

After each sip, there’s a brief, gentle floral aftertaste. It leaves my mouth feeling clean instead of sticky.

I think the combination of citrus and herbs makes this mocktail feel both grown-up and easy to enjoy. It’s one of those drinks you could serve just about anywhere, and people would probably ask for the recipe.

Substitute

Sometimes I just don’t have every ingredient on hand for this Lavender Grapefruit Soda Mocktail. No big deal—I’ve found a few easy swaps that still taste great.

Ingredient swaps:

If fresh grapefruit juice is missing from my fridge, I’ll grab orange or even lemon juice instead.
Lavender syrup’s not always in my pantry. I use plain simple syrup or honey, and if I’ve got it, a drop of food-safe lavender extract.
Club soda? Sparkling water or tonic water do the job just fine.

Non-alcoholic options:

Sometimes I toss in a splash of cranberry or pomegranate juice. It tweaks the flavor and honestly, the color looks pretty cool.
Want it sweeter? I just pour in a little extra syrup or a squirt of agave nectar.

Dairy-free options:
This one’s already dairy-free, so nothing to worry about there.
