Rhubarb Gin and Tonic

If you are looking for new flavours to infuse your G&T with you need to try Rhubarb Gin and Tonic! Rhubarb and lemon add to the bouquet of the classic cocktail, making a fun version that tastes like summer. Rhubarb G&T is a great summer cocktail to sip in the sun. Plus, it’s made with homemade rhubarb syrup that adds a lovely sweet and sour note while also colouring the cocktail pink!

Juniper may be king (or queen?), but all gins feature several botanicals. Some gins may list rhubarb among their ingredients, but even if they don’t most will be a great match with the stalky plant.

Rhubarb is known for its tartness, a characteristic that is also of citruses. Citrus peels feature among the most used botanicals in gin, and citruses are also often added to gin and tonics. Think of a lime wedge, perfectly complementing a classic G&T. While also using a rhubarb stalk as garnish, in this cocktail we are using rhubarb syrup.

Rhubarb gin and tonic ingredients

  • Gin*

The ingredients needed in this recipe on a dark wooden table.

When testing this recipe I decided to go full-rhubarb and chose both a rhubarb-infused tonic water and a rhubarb-infused gin. My choice of gin was Pink Gin by Stockholms Bränneri (more info here) and Nordic Tonic Rhubarb by Ekobryggeriet because I wanted to use 2 Swedish products. I have made this rhubarb cocktail several times also using other brands that were not infused with rhubarb and the result was excellent.

How to make it

  • Take a highball or balloon glass and fill it half full with ice cubes.
  • Add 6 cl (2 fl oz) rhubarb syrup and 3 cl (1 fl oz) gin.
  • Top with tonic water.
  • Add a slice of lemon and decorate with a rhubarb stalk if available.

To balance the sweetness of the rhubarb syrup and perfectly match the bouquet of the gin I recommend the use of tonic water (with quinine, so with a slightly bitter taste) rather than just simple carbonated water (club soda).

For a nice variation you can also try my rhubarb and redcurrant syrup as well as adding some frozen redcurrants in your cocktail. The cocktail will look an ever darker shade of pink.

The use of rhubarb-infused gin or rhubarb tonic water is nice but not mandatory. The rhubarb flavour is mostly supplied by the syrup so regular gin and tonic water will also deliver a great taste.
