The Gin Lemon is probably the most-drunk long drink in Italy after the gin and tonic, and at the same time the least documented: it isn't a codified cocktail, it appears in no international manual, and every bar makes it its own way. It's an Italian habit that became a standard.
That doesn't mean there's no right way to make it. There are ratios that work and ratios that turn it into any old alcoholic soft drink, and the difference lies almost entirely in two choices: which lemon soda you use and how much ice you put in.
What a Gin Lemon is
The Gin Lemon is a long drink built on gin and a lemon soft drink — sparkling lemonade, Lemonsoda, Schweppes Lemon or similar — served over plenty of ice in a tall tumbler and garnished with a lemon slice.
Its structural feature is that the sweet and the sour arrive together, from the mixer. In a Gin Fizz or a Tom Collins the bartender measures them separately (lemon juice on one side, syrup on the other); here they come pre-packaged. That's why the Gin Lemon is so simple to make, and also why it gives you less room to control the outcome.
A warning: there is no "IBA recipe" for the Gin Lemon
It's one of the most frequent searches about this drink, and the answer is blunt: the Gin Lemon is not an official IBA cocktail. It appears in none of the three International Bartenders Association lists — not the Unforgettables, not the Contemporary Classics, not the New Era Drinks.
If you're after the IBA cocktail it most resembles, that's the Gin Fizz: the same idea of gin and citrus, but with squeezed lemon, measured sugar and neutral soda in place of the ready-made mixer.
The ratios that work
In the absence of an official standard, the ratio most common in Italian bars is 1 : 3:
- 50 ml gin
- 150 ml lemon soda, thoroughly chilled
- Ice, enough to fill the glass
- A lemon slice or a strip of peel
Anyone who wants more of the spirit drops to 1 : 2.5 (50 ml gin, 125 of mixer). Push beyond 1 : 4 and the gin disappears, leaving lemonade with an alcoholic aftertaste: that's the Gin Lemon nearly everyone has had at least once, and the reason nearly everyone thinks the Gin Lemon isn't up to much.
How to make it
- Fill a tall tumbler with ice, right to the top. Not three cubes: to the top.
- Pour the gin over the ice. Gin first, always: it chills immediately, so the mixer meets an already-cold spirit.
- Add the lemon soda, pouring slowly down the inside wall of the glass so you don't lose the carbonation.
- Stir once, from the bottom up, with a long spoon.
- Garnish with a lemon slice, or express a strip of peel over the glass and then drop it in.
No shaker: the Gin Lemon is built directly in the glass. Shaking it only knocks the fizz out of the mixer.
Which lemon soda to use
This choice shapes the drink more than the gin does, because the mixer is three quarters of the glass.
- Lemonsoda and similar. The Italian benchmark: sweet, heavily carbonated, with a firm acidity. It gives the "classic" Gin Lemon everyone recognises.
- Schweppes Lemon or lemon tonic. Drier, with a bitter edge. The drink comes out less sweet and more grown-up — it's the version we prefer with a citrus-forward gin.
- Craft lemonade. Less sugar, more real juice. Excellent, but often lightly carbonated: the drink loses its sparkle.
- Sweet & sour. Some bars use it instead of the soda, lengthening with soda water. Technically that moves you towards a Gin Fizz.
Rule of thumb: the more aromatic your gin, the less sweet the mixer should be. High sugar flattens the botanicals and leaves you with nothing but the sensation of lemon.
Which gin to use
The Gin Lemon is less forgiving than it looks. The mixer covers a lot, but not everything: an anonymous gin becomes invisible here, and at that point you may as well drink the lemonade.
- Citrus-forward and Mediterranean gins: the most natural match. The citrus in the spirit and the citrus in the mixer add up rather than argue.
- Classic London Dry: works well, and the juniper plays against the sweetness. It's the most traditional choice.
- Floral or delicate gins: not advised. They get buried.
- Navy strength: excellent if you lengthen it further, because they hold up to dilution without vanishing.

Glass and ice
You want a tall tumbler (highball) of at least 30 cl. The narrow vertical shape holds the carbonation, and in a drink built on a fizzy mixer that's half the result. The copa de balón, excellent for a gin and tonic, loses the bubbles too fast here — we explain why in our guide to glassware.
On ice, the same rule applies as to every long drink: plenty of it, and big. Too little ice melts fast and waters the glass down halfway through; a full glass melts more slowly and keeps the drink cold and intact.
Gin Lemon or Gin and Tonic: what's the difference
Same structure — gin plus mixer, built over ice — but two opposite profiles:
- In the Gin and Tonic the mixer brings bitterness, from quinine. It's a dry drink that leaves room for the botanicals.
- In the Gin Lemon the mixer brings sweet and sour. It's a more immediate drink, more refreshing and easier to drink.
Put another way: the gin and tonic is the drink of gin enthusiasts, the Gin Lemon is the drink of summer. If it's the former you're after, our step-by-step guide to the gin and tonic covers ratio, ice, tonic and garnish.
Gin Lemon or Gin Fizz
They resemble each other in the result but not in the method. The Gin Fizz is shaken with squeezed lemon and sugar syrup measured separately, and finished with neutral soda; the Gin Lemon is built in the glass with a mixer that did that job in a factory.
The practical consequence: the Fizz lets you control acidity and sweetness to the millilitre, the Gin Lemon doesn't. In exchange, you can make a Gin Lemon in twenty seconds with no equipment. You'll find the official recipe for the former in our guide to the Gin Fizz.
How strong it is, and how many calories
A Gin Lemon in the classic proportions (50 ml of gin at 40% in roughly 200 ml total) lands at around 10% ABV. It therefore contains about 16 grams of alcohol: a little over two UK units, roughly the same as a pint of beer or a large glass of wine.
So it isn't a "light" drink just because it's sweet and refreshing — on the contrary, the ease of drinking is exactly what makes it deceptive: the sweetness masks the alcohol and it goes down faster than a gin and tonic. Worth knowing, and worth pacing.
On calories we're at around 170–190 kcal a glass: roughly 110 from the gin and the rest from the sugar in the mixer. A zero-sugar version brings it under 120.
Measures for a jug or a litre
To serve several people, keep the 1 : 3 ratio and make it to order, not in advance:
- 1 litre of Gin Lemon: 250 ml gin + 750 ml lemon soda, plus ice in the glasses.
- For 6 people (200 ml glasses): 300 ml gin + 900 ml mixer.
Two cautions: the ice goes in the individual glasses, not in the jug, otherwise it dilutes everything while it waits; and the mixer goes in last, because in a jug it goes flat within minutes.
The alcohol-free version
Swapping the gin for a non-alcoholic botanical spirit gives you a credible drink, because the structure of the Gin Lemon holds up without alcohol: the mixer is doing most of the work anyway. With plain lemonade and a strip of peel, on the other hand, you have lemonade — pleasant, but a different thing.
The most common mistakes
- Not enough ice. The most widespread and the most damaging: the glass should be filled, not decorated with cubes.
- Room-temperature mixer. The ice melts immediately to chill it and the drink is born watered down.
- Too much mixer. Beyond a 1 : 4 ratio the gin can no longer be tasted.
- Over-stirring. Every extra turn is carbonation lost.
- Squeezing half a lemon in. It adds acidity to a mixer that is already acidic and throws everything off. The peel is enough.
Frequently asked questions
How do you make a Gin Lemon? Fill a tall tumbler with ice, pour in 50 ml of gin, add 150 ml of chilled lemon soda down the side, stir once and garnish with a lemon slice.
What's the difference between a Gin Lemon and a Gin and Tonic? The mixer: the Gin Lemon uses a lemon soda, sweet and sour; the Gin and Tonic uses tonic water, bitter from quinine.
How strong is a Gin Lemon? Around 10% ABV in the classic proportions, which is a little over two UK units per glass.
Is the Gin Lemon an IBA cocktail? No. It isn't an official cocktail. Its closest IBA relative is the Gin Fizz.
Which gin should I use for a Gin Lemon? A citrus-forward gin or a London Dry with character. Delicate gins get covered by the mixer.
Can I use lemon tonic? Yes, and it's the least sweet version: the drink comes out drier and suits aromatic gins better.
The Gin Lemon with GIN NIRO
A gin built on citrus in a drink built on lemon: the risk would be redundancy, and yet it works, because the two components operate on different planes. The mixer brings the acidity and the sweetness; the spirit brings the aromatic part — the peel, its essential oils, the grape.
GIN NIRO — the Sicilian gin distilled with Zibibbo grapes — is at its best in this drink with a low-sugar mixer: 50 ml of gin, 150 of lemon tonic or dry lemonade, plenty of ice, a strip of lemon peel expressed over the top.
If you're curious where that citrus note comes from before it ever reaches the glass, we've devoted a piece to Sicilian lemon as a botanical — the peel that goes into the still, not the slice that ends up in the drink. They're two different things, and it's a distinction worth having clear.
