Are you looking for a new, refreshing drink? This Rosemary and Gin Grapefruit Cocktail is the answer you’ve been looking for. Fizzy, sweet, and not too strong, with a delicious herbal, fruity taste, it’s the perfect drink to carry you through the evening.


  • 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.
  • 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

Adding sugar to pot for simple syrup

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

Liz cutting fresh rosemary

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.

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.

For a bit of added fun to your cocktail, run a lime wedge around the edge of each glass.

Coating glass rim in salt

Dip and swirl the glass rims in a plate of kosher salt to gain a salted rim to pair with the sweet, tart drink.
