Serving Size

Equipment

Cocktail shaker or large jar with a tight lid
Measuring jigger or small measuring cup
Strainer (if your shaker doesn’t have one)

Muddler or the back of a spoon
Citrus juicer
Small saucepan for making rosemary syrup
Fine mesh sieve (for straining syrup)

Tall cocktail or wine glasses
Bar spoon: for stirring.

Ingredients

2 oz fresh grapefruit juice
1 oz rosemary simple syrup see notes
4 oz chilled Prosecco
1 small sprig of rosemary for garnish
1 slice fresh grapefruit for garnish
Ice cubes
Optional extra grapefruit juice for a less sweet taste

Instructions

Fill the cocktail shaker with ice.
Add grapefruit juice and rosemary simple syrup.
Shake well for about 10–15 seconds.

Strain into a tall glass filled with fresh ice.
Gently top with chilled Prosecco.
Stir lightly to mix.
Garnish with a sprig of rosemary and a slice of grapefruit.

Notes

To make rosemary simple syrup, I combine 1/2 cup sugar, 1/2 cup water, and 2 rosemary sprigs in a small saucepan. I bring it to a simmer, stir until the sugar dissolves, and then let the mix cool with the rosemary still inside.

After cooling, I strain it and keep it in the fridge for up to a week. This drink tastes best very cold.

I always chill my glassware and Prosecco before making it. If the drink is too sweet, I add more grapefruit juice.

For a less strong rosemary taste, I use less syrup or skip the garnish. Adjust the syrup and juice to your taste—honestly, it’s hard to mess it up.

Tasting Notes

When I take my first sip, I notice the initial burst of grapefruit. It has a bright, tart flavor that wakes up my taste buds.

The prosecco brings gentle bubbles and a subtle sweetness. It balances the tangy citrus and feels light on my palate.

I can taste the rosemary next. Its herbal note is fresh, not overpowering.

It adds a clean finish and a hint of earthiness. That’s probably my favorite part.

Flavor Highlights

Tart: The grapefruit stands out right away.

Herbal: The rosemary offers a soft, woody taste.
Bubbly: Prosecco makes every sip lively.

As the glass warms slightly, the rosemary scent becomes stronger. This makes each sip a little more layered.

The finish is crisp, and a gentle bitterness from the grapefruit lingers. It makes me want to take another sip.

Substitute

Sometimes I need to make swaps if I don’t have all the ingredients on hand.

Here are a few simple substitutes for this cocktail:

Ingredients:

Prosecco: I sometimes use Cava, Champagne, or sparkling white grape juice for a non-alcoholic version.
Grapefruit juice: I swap with orange juice, blood orange juice, or even pomegranate juice for a different flavor.
Rosemary sprig: When I’m out of rosemary, I garnish with a thyme sprig or a mint leaf instead.

Equipment:

I use a standard wine glass, but a champagne flute or tumbler works if that’s all I have.
If I don’t have a cocktail jigger, a tablespoon or shot glass helps measure liquids.

Instructions:

I pour the sparkling wine slowly to keep it fizzy.

If I use a different juice, I adjust the amount to taste since some juices are sweeter or more tart.
For a sweeter drink, I add a splash of simple syrup or honey.
If fresh herbs aren’t available, a drop of food-safe rosemary or citrus extract can add aroma.
