This sparkling grapefruit mocktail with smooth rosemary syrup is an amazing explosion on the tastebuds.

I'm not a huge sweet tooth, so grapefruit is one of my all time favourite fruits. The rosemary compliments the grapefruit nicely and if you love grapefruit like me, be sure to try my easy mocktail palomas too.

Even better, grapefruit is loaded with nourishing vitamins, and is even more nutrient dense than oranges. Itโ€™s great for your immune system and high in antioxidants.

It can be quite bitter depending on the season and your supplier, so I have been conservative with my measurements below. Feel free to add more grapefruit juice should you wish.

This would make a great mocktail for kids too - my kids love it!

The rosemary syrup is a little bit of work, but you only need a small amount for the actual drink. You can save the rest to use for another drink, or in a different recipe. This can also be made in advance if you are having guests. Just squeeze the grapefruit and prepare the syrup before you guests arrive. Once they arrive, measure the quantities into each glass and top with sparkling water and ice.

Another option is to double or triple the servings and make this in a jug, then top with slices of grapefruit and sprigs of rosemary.

I hope you enjoy this grapefruit mocktail as much as I enjoyed making it.
