Grapefruit and rosemary gin cocktail

How is you cocktail game at the moment? We all have those days there the thing you need in your life is something fun to drink. Sometimes it’s a special occasion and sometimes that special occasion is surviving Tuesday. If you are needing something a little bit different in your life then this grapefruit and rosemary gin cocktail is where it is at right now.

Over the last couple of years we’ve all seen quite a big rise in the number of cocktail bars out there and more and more of us are making better cocktails at home. Gone are the days where chucking a few things in a cocktail shaker and calling it quits was making drinks, we’re now more adventurous whether we’re out or have people over.

This grapefruit and rosemary gin cocktail is perfect on many grounds, but one of its advantages is that it’s so flexible. Whether you are looking for a boost to your evening, wanting to relax on a sunny afternoon or are having people over for brunch, this recipe is perfect. It’s also not complicated in any way shape or form, so you don’t have to be a master mixologist to get it right (and yes, I can confirm that it’s easy to make if you’re having a hair-of-the-dog brunch).

If you’re worried about non-grapefruit loving friends, you can also easily up the amount of rosemary syrup you include. Not only is it there to bring different layers of flavour, it also sweetens the drink. Gin and grapefruit on their own are quite harsh flavours, so a little sweetness certainly helps this taste a little more delicious.

What gin to use?

Most gins will work in this cocktail. I used one of my favourite gins for cocktails: Aviation American gin. It’s US heritage means its made with cocktails in mind – lot of UK-made gins are more thought about with a gin and tonic – so it’s really quite smooth.

How do you make simple syrup?

Simple syrup always sounds a bit daunting, but once you’ve made it once you’ll realise just how easy it is. It’s also something that’s really easy to make in bulk, if you’re planning on making quite a lot of cocktails. The recipe is down below, but in essence, it’s about putting water and sugar in a pan, dissolving the sugar and then reducing the mixture. You can make it plain or with a flavour such as rosemary. It takes 10-15 minutes to make and then you just need to let it cool before using it.

This is a ridiculously refreshing cocktail. It’s also got a bit of tang to it – a great alternative to some of the overly sweet cocktails out there. With a great balance between citrus and gin goodness, this is perfect for a burst of colour in your day, for brunch or to cool down in the summer.



  • 3 parts gin
  • 3 parts grapefruit juice
  • 1 part rosemary simple syrup (see below)
  • Soda water to taste
  • Rosemary to garnish
  • Ice


Combine the gin, grapefruit juice and rosemary simple syrup in a cocktail shaker that’s filled with ice. Shake vigorously to mix and then pour into glasses over ice.

Top up with soda water as desired and garnish with a sprig of rosemary.


To make the rosemary simple syrup

In a medium saucepan, put most of a pack of rosemary – at least 4 or 5 large sprigs, if using directly from a bush – along with 150ml water and 1 tablespoon of caster sugar. Heat on medium until the sugar has dissolved and then reduce down to about half the volume. Set aside to cool before use.
