When Dan and I participated in Dry January last month, we each found a few favorite mocktail recipes to enjoy. Most of the time we just drank water or hot tea, but there were certain nights when we wanted something a little more festive.

I’m a huge fan of anything that is grapefruit flavored. I love the sweet and tartness of it. It’s like Orange Juice 2.0.

Rather than just enjoying a grapefruit flavored sparkling water, I wanted to come up with an easy drink recipe that was made with simple ingredients. If you make the simple syrup in advance, this drink comes together in less than one minute!

Check out these 15 Refreshing Mocktail Recipes for great non-alcoholic drink inspo.

Making your own Grapefruit Sparkling Water Drink

Just 3 ingredients are needed for this flavorful mocktail –

  • plain sparkling water
  • fresh squeezed grapefruit juice
  • simple syrup

If you’ve never made a simple syrup, it’s easy and works great in many cocktails and/or cocktails. Simply place 1/2 cup of sugar and 1/2 cup of water in a small saucepan. Over medium heat, stir until the sugar is dissolved into the water. Let cool and then store leftover in fridge.

You could easily used store bought grapefruit juice or grapefruit flavored sparkling water but I like the idea of controlling the ingredients and using the freshest of foods.

This Whiskey Sour Mocktail is one of my favorite ways to use homemade simply syrup.
