Bright, herbal, and refreshing, this Rosemary and Gin Grapefruit Cocktail recipe combines citrus and botanicals for the perfect easy gin drink.

Looking for a refreshing, citrus-forward cocktail to shake up your routine? This Rosemary and Gin Grapefruit Cocktail is light, fizzy, and perfectly balanced with sweet, herbal notes. Fresh grapefruit juice adds bright flavor while rosemary syrup brings a cozy, aromatic touch that pairs beautifully with gin. Whether you’re hosting friends or relaxing after dinner, this easy gin cocktail is just as effortless as my Spicy Jalapeño Margarita or Lemon Basil White Wine Spritzer.
Ingredients
- Gin: Has a strong citrus scent and almost pine like flavor, as it is made from juniper berries.
- Grapefruit juice: Sweet, tart, acidic, and a popular pairing with gin.
- Lime juice: Bright, fresh, acidic flavor that complements the grapefruit.
- Club soda: Helps to balance out the flavors so the drink isn’t too intense. My favorite is La Croix, and I’ll use lime flavored instead of plain for an added punch of flavor. It also gives the drink some bubbles!
- Rosemary simple syrup: The sweet sugar mixed with the vibrant rosemary flavor pairs exceptionally well with gin.
How to Make Rosemary and Gin Grapefruit Cocktail

Step 1. Start by making the simple syrup. Measure out your sugar into a saucepan, add the water, and melt over medium-high heat until sugar dissolves.

Step 2. Trim a couple sprigs of fresh rosemary. Rosemary is a perfect indoor plant to keep for fresh herbs, but you can also buy sprigs from the grocery store.

Step 3. Once your sugar water mixture is boiling, remove from heat, and add the rosemary sprigs. Let the rosemary steep in the syrup until it is cool, at least a couple hours.

Step 4. For a bit of added fun to your cocktail, run a lime wedge around the edge of each glass. Dip and swirl the glass rims in a plate of kosher salt to gain a salted rim to pair with the sweet, tart drink.

Step 5. Start your drinks by filling each cup with ice, and adding the gin.

Step 6. Next, add the grapefruit and lime juice to each glass.

Step 7. Now that it’s cool, strain your rosemary simple syrup and add that to each glass.

Step 8. Top off each glass with club soda to the rim.

Alternatively, you could make it in a cocktail shaker. If you’re feeling fancy, garnish each glass with a slice of grapefruit and a rosemary sprig. Serve, and enjoy this delicious cocktail!

Instructions
- Begin making the rosemary simple syrup by heating the sugar and water in a small sauce pot over medium high heat. Bring to a boil then remove from the heat. Whisk until the sugar is completely dissolved. Add the rosemary sprigs then let steep until cool, at least 2 hours or up to three days. Strain the rosemary sprigs before using.
- To create a salt rim for the glasses, place about 1/2 cup of coarse Kosher salt on a plate. Run a lime wedge around the rim of four cocktail glasses then gently run the glass rim around the salt to coat; set aside.
- In a large pitcher, mix together the gin, grapefruit juice, lime juice, and rosemary simple syrup. Stir well.
- Fill each glass with ice then pour the gin and juice mixture 2/3 way full. Top each glass with club soda and garnish with lime wedge or rosemary sprig to serve.
