Ingredient Notes

ingredients to make a grapefruit cocktail

Fresh Rosemary: Fresh is best for this rosemary cocktail, for both the simple syrup and the garnish. If you have a home garden, I recommend growing your own rosemary! It’s super easy and so nice to have on hand.

Sugar: This grapefruit cocktail recipe calls for 2 cups of regular sugar for the simple syrup. You can also sub monk fruit sweetener or Swerve, or another 1:1 sugar replacement if you’re looking to make a “skinnier” grapefruit cocktail version.

Vodka: Use your favorite!

Grapefruit Juice: I like Ruby Red for this rosemary cocktail recipe, but to make it skinny, you could also use freshly squeezed grapefruit juice, so know it’ll be a little more tart.

Recipe Step by Step

Rosemary Simple Syrup

  1. In a small saucepan over medium-low heat, dissolve the sugar into the water for about 5 minutes. Do not let the mixture boil or crystals will form.
  2. In a heat-safe container, pour the warm sugar water mixture over the rosemary sprigs and let it steep for at least 1 hour.
  3. The simple syrup will keep in the refrigerator in an airtight container for 10 days.
