R A Short History of the Classic Gin & Tonic

 

The Classical Gin and Tonic – A Timeless Recipe

Few cocktails in the world have achieved the universal recognition and timeless elegance of the gin and tonic. From its colonial roots in the tropics to its modern reinvention in cosmopolitan bars, the gin & tonic remains one of the simplest yet most refreshing mixed drinks ever created. While there are countless variations today — infused with exotic botanicals, fruit garnishes, and craft tonics — the classical gin and tonic recipe remains the benchmark for balance, crispness, and sophistication.

A Short History of the Classic Gin & Tonic

The origins of the gin & tonic go back to the 18th and 19th centuries, when British soldiers and officials stationed in India faced the risk of malaria. Quinine, a bitter compound derived from cinchona bark, was used as a treatment. To make quinine more palatable, it was mixed with water, sugar, and soda, eventually leading to tonic water.

To improve the taste further, officers added gin, creating what we now know as the gin & tonic. From this medical necessity, a refreshing cocktail was born. By the mid-19th century, the gin & tonic was entrenched in British colonial life, and later became a global classic, served from London clubs to Caribbean resorts.

The Essential Elements of a Classical Gin and Tonic

A true classical gin & tonic is all about simplicity and balance. Unlike many modern cocktails, it requires only a few high-quality ingredients.

1. The Gin

Traditionally, the gin used is a London Dry Gin, known for its crisp juniper-forward profile. Classic choices include:

• Beefeater

• Tanqueray

• Gordon’s

These gins offer the clean, herbal backbone that defines a proper G&T.

2. The Tonic Water

The tonic is equally important. Historically, tonic water was bitter due to high quinine levels. Modern versions are lighter and more refreshing. For the classic recipe:

• Schweppes Indian Tonic Water is the standard traditional choice.

• Fever-Tree Indian Tonic is a premium alternative.

3. The Garnish

The classic garnish is a wedge of lime. Lemon can also be used, but lime became the international standard thanks to its slightly sharper acidity and vibrant aroma.

The Classical Gin & Tonic Recipe – Step by Step

Ingredients:

• 50 ml (1.7 oz) London Dry Gin

• 100–150 ml (3.5–5 oz) Indian Tonic Water (chilled)

• 1 wedge of fresh lime

• Plenty of ice cubes (large, solid ice is best to avoid dilution)

Preparation:

1. Chill the Glass
   Use a highball glass (the classic vessel) or a balloon-style copa glass (popular in Spain). Place the glass in the freezer for a few minutes, or fill it with ice to chill it thoroughly.

2. Add the Ice
   Fill the glass to the top with large, fresh ice cubes. The more ice, the slower it melts, keeping the drink crisp.

3. Pour the Gin
   Measure 50 ml of London Dry Gin and pour it over the ice. This ensures proper strength and balance.

4. Add the Tonic
   Slowly pour 100–150 ml of chilled tonic water into the glass. To preserve carbonation, tilt the glass or pour gently down a bar spoon.

5. Garnish
   Squeeze a wedge of lime lightly over the drink, then drop it into the glass. Avoid muddling or over-squeezing — the lime should complement, not overpower, the gin’s botanicals.

6. Stir Lightly
   Give the drink one gentle stir to combine, being careful not to lose carbonation.
