Flavoured syrup

  • 2
  • 2 cups (330 g)
    fresh pineapples, chopped
  • 6
    sprigs fresh rosemary
  • ½ cup (120 mL)
  • ⅓ cup (75 g)
    granulated sugar


  • 3 cups (333 g)
    ice cubes
  • 1½ cups (360 mL)
    grapefruit juice
  • 3 cups (720 mL)
    carbonated water

Optional garnish

  • sprig fresh rosemary
  • grapefruit wedges


  1. Start with zesting the grapefruit. Reserve the zest for later.
  2. Add the juice from the same grapefruit to a saucepan, along with the remaining syrup ingredients. Cook uncovered at a gentle simmer for 10 - 15 minutes. Stir often.
  3. Then add the grapefruit zest to the saucepan. Use a wooden spoon or tamper to mash the pieces of pineapple to release their juices and flavours.
  4. Place a sieve over a bowl or pitcher and strain the mixture. Use the back of a spoon to press out as much liquid as possible. Let cool completely.
  5. Divide the ice between the glasses. To each cup, add 1 part syrup, 1 part grapefruit juice, 2 parts carbonated water. Garnish and enjoy!


  • The drink is best enjoyed immediately.
  • The simple syrup can be made ahead and stored in a glass jar in the fridge for up to 3 days.

Refreshing and delicious!

Could I use frozen mixed berries or fresh/frozen oranges in place of pineapple?

Hey Sydney, we haven't tried but mixed berries or oranges sound like a delicious alternative. It'll add a unique twist to the spritzer. Let us know how it goes if you experiment with it 🤗

This is soooo good! Making a bigger batch next time 🥰

It smelled great but came out super tart and almost bitter. I had to add a tonne of sugar. What can I do different to avoid this?

PUL Team - June 6, 2022, 7:01 p.m.

Hey there, Pk, thank you for sharing your experience with it. How disappointing! Using a ripe grapefruit is helpful since they tend to be more tangy than unripe grapefruit which are more bitter. Mashing the pineapple chunks well also helps release more of the sweet juices to balance the flavour. We hope this helps for now 🙂

This was delicious. I batch made double the syrup, and enjoyed it every evening! Also substituted the grapefruit juice for orange juice, which was also great.
Thanks for sharing the recipe.

Thanks for sharing your experience with it, Jigya, it's so appreciated!

This is so good!!! The combination of grapefruit and rosemary is a dream.
I used frozen pineapple, because I couldn't get it fresh, and that worked out just as good.

Constanze - Aug. 9, 2021, 8:49 p.m.

I made this twice already and find it very nice and refreshing. I used orange instead of the grapefruit juice when putting the drink together in order to use up those oranges.

PUL Team - Aug. 10, 2021, 4:17 a.m.

Mmm love the idea for oranges, Constanze, thanks!

Georgiana - July 15, 2021, 10:08 a.m.

Delicious indeed! The pineapple and grapefruit combo is a dream, plus the rosemary... yummy! I feel like on a vacation every time I have this drink!
I really recommend this one to everyone!

P.S.: Too bad I cannot add a picture of it!

Love this one sooo much! I'm not a fan of grapefruit, but this recipe made me obsessed with it now!!

Délicieux ! Très frais. Un peu de soleil dans le verre sous la pluie. Les enfants ( 6 et 7 ans) ont adoré.

Delicious ! Very fresh. A little sun in the glass in the rain. The kids (6 ans 7 y) loved it!

PUL Team - June 29, 2021, 2:33 a.m.

Woohoo! So happy the little ones enjoyed it, Loutre, thank you :)

Louise - May 23, 2021, 12:09 a.m.

This was such a nice, fresh drink! I also tried to swap out one part carbonated water with one part gin, and it turned out really well too. :)

PUL Team - May 23, 2021, 12:41 a.m.

Thank you for the review, Louise, so glad you enjoyed the drink!
