A gin and tonic has two ingredients, so ratio, ice and tonic quality decide how good it is. Lots of ice keeps it from going flat.

Ingredients

Makes
  • 50 ml Gin
  • 150 ml Chilled tonic water
  • 1 wedge Lime or cucumber slice For the garnish

Garnish: Lime wedge or cucumber slice

How to Make a Gin and Tonic

  1. Fill a large glass with ice to the top.
  2. Add the gin.
  3. Pour chilled tonic slowly down the side of the glass.
  4. Stir once, gently.
  5. Add the garnish.

Tips for a Better Gin and Tonic

  • Fill the glass completely with ice. More ice means slower melting and a cooler drink.
  • Pour tonic down the side or down a bar spoon to keep the bubbles.
  • Buy small bottles of tonic. Once opened, the fizz fades within hours.

About the Gin and Tonic

The Gin and Tonic began as medicine in British India. Quinine, extracted from cinchona bark, was the only effective protection against malaria in the 19th century, and it was intensely bitter. Officers of the British Indian Army took their daily dose dissolved in water with sugar and lime, and added their gin ration.

Commercial tonic water followed. Erasmus Bond patented the first one in London in 1858, and Schweppes launched its Indian Quinine Tonic in the 1870s. Modern tonic contains far less quinine, enough for flavour but not for medicine.

The drink was reinvented in Spain in the 2000s as the "gin-tonic": a large balloon glass, plenty of ice, premium tonic and a garnish chosen to match the gin. That style spread through Europe, the United Kingdom and Australia and fuelled the craft gin boom, including India's own new wave of gins.

Gin and Tonic Variations

  • Spanish Gin-Tonic: a balloon glass, lots of ice and botanicals such as juniper berries, citrus peel or rosemary.
  • Pink Gin and Tonic: pink gin with strawberries, or a dash of Angostura bitters.
  • Gin Sonic: half tonic and half soda water for a drier, lighter drink.
  • Elderflower Gin and Tonic: add 10ml of elderflower cordial or use elderflower tonic.
  • Nimbu Pani Gin Cooler: an Indian take with salted lemonade and roasted cumin.

Frequently Asked Questions

What is in a Gin and Tonic?

A Gin and Tonic is made with 50ml (1.75 oz) gin and 150ml (5 oz) chilled tonic water. It is served in a highball or balloon glass.

How strong is a Gin and Tonic?

Made to this recipe, a Gin and Tonic is about 9% ABV and contains roughly 16 g of pure alcohol. That is about 1.1 US standard drinks, 1.6 Australian standard drinks or 2.0 UK units. It has around 160 calories per serving.

What is the best gin to tonic ratio?

Use 1 part gin to 2 or 3 parts tonic. This recipe is 50ml gin to 150ml tonic, a 1:3 ratio. Use 1:2 for a stronger, more gin-forward drink.

What is the best gin for a Gin and Tonic?

A juniper-led London dry gin such as Tanqueray, Bombay Sapphire or Gordon's is the benchmark. Contemporary gins with citrus or floral botanicals suit lighter tonics.

Which garnish goes with which gin?

Match the gin. Use lime or lemon for classic London dry, cucumber for Hendrick's, grapefruit or orange peel for citrus-led gins, and rosemary or peppercorns for savoury gins.

Does tonic water prevent malaria?

No. Modern tonic water contains at most about 83mg of quinine per litre, the legal limit in the United States, which is far below a medicinal dose.
Drink responsibly. The legal drinking age in India varies by state, from 18 to 25. Alcohol content shown is an estimate and changes with ice, dilution and the strength of the bottle you use. We do not sell alcohol.
