Gin and Tonic
Gin, tonic, ice and citrus. The simplest serious drink in the world, and the one most often made badly — the fix is cold, a good tonic and a lot of ice.
Built to the standard modern spec; not yet tested in our kitchen. How we test.
The recipe.
Scaling adjusts quantities only. Prepare shaken drinks in individual portions.
Let’s make a good drink.
Fill a highball or large wine glass to the top with ice. More ice means less melt, not more dilution.
Pour in the gin and squeeze the citrus wedge over it, then drop it in.
Add the tonic slowly, down the side of the glass or over a bar spoon, to keep the fizz.
Stir once, gently, from the bottom, and serve.
A thoughtful finish
- Open a fresh small bottle of tonic for each drink. Flat tonic from a litre bottle opened yesterday is the single most common reason a G&T disappoints.
- Chill everything. Gin from the freezer, tonic from the fridge, a glass that has sat on ice — a cold drink keeps its carbonation and its bite.
- Match the garnish to the gin: lime for a classic London dry, grapefruit for a citrus-led gin, cucumber for one that leans that way. It is a seasoning, not a decoration.
Common mistakes
- Three ice cubes in a warm glass. The ice melts fast, the drink goes flat and watery, and the tonic warms before you have finished it.
- Diet tonic in a drink you care about. Artificial sweeteners read as bitter against gin.
- Drowning it. More than roughly two to one tonic to gin and the gin disappears.
A few good questions.
What is the best ratio?
Two to one tonic to gin is the modern standard; three to one is a longer, lighter drink; the Spanish serve is often closer to two and a half. Start at two and adjust.
Which tonic?
A dry, lightly sweetened tonic with real quinine. The premium brands differ mostly in sugar and in the botanicals they add; a plain 'Indian' tonic suits almost every gin.
Lime or lemon?
Lime is the British default and brightens a juniper-heavy gin; lemon is softer and suits gins with more citrus. Spanish bars use whatever the gin suggests.
Why the big balloon glass?
The Spanish copa de balón holds more ice and traps the aromatics above the drink. It is not required, but it does make the drink colder and more fragrant.
Variations
- Vodka Tonic — Vodka for the gin.
- Tom Collins — Gin, lemon, sugar and soda — the sweet-and-sour cousin.
- Gin Rickey — Gin, lime and soda, no tonic.
- Mezcal Tonic — Mezcal for the gin, with grapefruit.
Where it comes from
c. 1850s–1870s · British India
Quinine, from cinchona bark, was the only effective treatment for malaria, and the British East India Company’s officers and soldiers took it daily in bitter solution. Sweetened and carbonated, it became tonic water — Erasmus Bond patented an aerated tonic in 1858, and Schweppes launched its Indian Tonic Water in 1870 — and the gin ration that went into it was already on hand. The drink was less an invention than an inevitability. It came home to Britain with the Empire, and the twenty-first-century Spanish habit of serving it in a large balloon glass with elaborate garnish gave it a second life as a craft cocktail.
