Elderflower Collins
The Elderflower Collins is a Tom Collins with the sugar upgraded to blossom. Gin, lemon and soda are unchanged; twenty millilitres of elderflower liqueur stands where the syrup would, and the whole drink reorganises around it. That is the same single move the Gold Rush makes with honey and the Army & Navy makes with orgeat: replace the neutral sweetener with one that brings character. Elderflower's lychee-and-blossom perfume threads through the gin's botanicals and the lemon's bite, and the soda lifts all three. Nobody owns it. It condensed out of the elderflower boom that followed the launch of the best-known liqueur in 2007: bartenders reached for the Collins template as the obvious frame, and the pairing was standard within about five years before anyone thought to claim it. That is folk repertoire of the modern era, which is a real pedigree even without a name attached to it, and it is how most long drinks were arrived at before anybody kept records.
Glassware: Collins Glass
Garnish: Lemon Wheel and Fresh Mint Sprig
Ingredients
45ml
The frame, and a botanical spirit meeting a blossom liqueur from broadly the same landscape. A London Dry keeps juniper audible underneath; a floral contemporary gin doubles up on what is already there.
20ml
The sweetener with a garden attached, standing where plain syrup would. Twenty millilitres perfumes the drink; thirty takes it over, and elderflower does not take over gently.
25ml
The Collins acid, keeping the blossom honest. Twenty-five millilitres is a full measure, because the liqueur brings sweetness that plain syrup would not.
90ml
A generous top over fresh ice, and it is doing more than lengthening: carbonation lifts the florals out of the glass and puts them on the nose before the first mouthful.
Instructions
Add the gin, elderflower liqueur and lemon juice to a shaker.
Fill with cubed ice and shake for 10 seconds.
Strain into a collins glass filled with fresh ice.
Top with the soda water and stir once.
Garnish with a lemon wheel and a slapped mint sprig.
Expert Tip
Hold the liqueur at twenty millilitres. Elderflower is a lead perfume rather than a background note, and the line between garden and gift shop is about ten millilitres wide. At twenty it is fully floral and still recognisably a gin drink; at thirty it is pot-pourri. Shake the base and add the soda in the glass. Shaking anything carbonated is a waste of both the soda and the effort, and the gin, liqueur and lemon want the aeration that soda does not. Slap the mint rather than muddling it. One clap between the palms wakes the oils without releasing the chlorophyll, and the sprig is working on the nose rather than in the liquid.
Flavour Profile
Where It Comes From
The drink has no author, and the reason is instructive. St-Germain launched in 2007 and elderflower liqueur went from an obscure category to something every bar had within about two years.
When a new bottle arrives, bartenders test it against the templates they already know. The Collins is the most forgiving long-drink frame there is, so it was one of the first things anybody tried, and the result was good enough that the pairing became standard before anyone thought to name it or claim it.
That is folk repertoire of the modern era: owned by everybody, disowned by nobody, and none the worse for either.
The Sweetener Swap
Structurally this is a Tom Collins with one substitution. Gin, lemon, soda, tall glass, plenty of ice. The syrup becomes elderflower liqueur.
It is the same move the Gold Rush makes with honey and the Army & Navy with orgeat, and it works for the same reason: a sweetener that brings character reorganises a drink around itself rather than just balancing it.
What makes this particular swap the survivor of the elderflower wave is affinity. Elderflower's perfume sits naturally alongside gin's botanicals, both being hedgerow flavours in a broad sense, and against lemon it reads as floral rather than as sweet. A great many elderflower drinks from that period have not lasted. This one did.
The Dose Discipline
Twenty millilitres is the calibrated measure and it is worth respecting.
Elderflower is one of the most assertive perfumes available behind a bar. It is not like sugar syrup, where more or less shifts a balance gradually; it behaves more like absinthe or rose water, where there is a threshold beyond which it stops being an ingredient and becomes the whole drink.
At twenty the glass is fully floral and still legibly gin. At thirty it is pot-pourri, and no amount of extra lemon brings it back. If in doubt, go under: you can always add a barspoon.
The Cordial Version
Elderflower cordial makes a genuinely good alcohol-free version, and it is a different build rather than a compromise.
Cordial is non-alcoholic and considerably sweeter per millilitre than the liqueur, so swap it in at the same measure and reduce or remove any other sweetening. It also has less body, which shows most in the middle of the drink.
Cordial with lemon and soda over ice is a very good long drink in its own right, and it is what a good many people's grandmothers were making long before any of this.
How to Serve It
Shaken base, strained over fresh ice in a collins glass, generous soda, one stir. Lemon wheel and a slapped mint sprig.
Tall, cold and outdoors by preference. It is high summer's Collins and it sessions as gently as anything gin does. Make one beside a Tom Collins once for the cleanest demonstration of what a sweetener with opinions actually does.
The Spirit
GinA flavour requirement rather than a method. The law asks only that juniper be the predominant taste and that the spirit reach 37.5%, which leaves everything else on the botanical bill to the distiller and permits a gin that was never redistilled at all.
Frequently Asked Questions
What is an Elderflower Collins?
A Tom Collins with elderflower liqueur in place of the sugar syrup: gin, lemon, elderflower and soda over ice in a tall glass. The liqueur sweetens and perfumes at the same time, which plain syrup cannot do.
How much elderflower is too much?
Anything past about twenty-five millilitres. Elderflower is an assertive perfume with a threshold rather than a gradient: at twenty the drink is floral and still legibly gin, and at thirty it is pot-pourri. There is no recovering an over-poured one.
Can I use elderflower cordial instead?
Yes, and it makes a good alcohol-free version. Cordial is sweeter per millilitre and has less body, so swap at the same measure and remove any other sweetening. It is a different build rather than a compromise.
How does it differ from a Tom Collins?
One ingredient. The Tom Collins uses sugar syrup; this uses elderflower liqueur, which sweetens and brings a floral character at the same time. Everything else, including the gin, the lemon and the soda, is unchanged.

Tom Collins
The Tom Collins is a gin sour lengthened with soda: gin, fresh lemon, sugar syrup and soda water over ice in a tall glass. The simplicity is deceptive. Built with a quality London Dry, lemon squeezed to order and well-chilled soda poured carefully, it is one of the most refreshing long drinks there is. Built with bottled juice and flat soda, it is one of the most disappointing. The name comes from one of the odder stories in the canon. The Great Tom Collins Hoax of 1874 involved telling somebody that a man called Tom Collins had been disparaging them in a nearby bar, then sending them off to find a person who did not exist. It spread across American cities fast enough that the name entered everyday speech, and a long gin drink already being served as the John Collins acquired it almost by association. Old Tom gin, the sweeter style that preceded London Dry, was the format's original base and makes a rounder, gentler drink. Both are correct.
Gin Basil Smash
The Gin Basil Smash is the modern classic with a precise birthday: July 2008, Le Lion in Hamburg, where Jörg Meyer muddled a fistful of basil into a gin sour and watched the result go green and go global. Within two years it was poured from Sydney to San Francisco, and it remains the fastest-adopted European drink of its generation. The build is a smash in the Jerry Thomas sense with the herb turned hero: basil muddled firmly with lemon, gin shaken through, the whole double-strained into a vivid chlorophyll glass. Basil behaves better than mint under violence, its deeper oils releasing pepper and anise without bitterness, and the drink tastes like a herb garden with a law degree. Meyer named it the Gin Pesto at first, thought better of it, and the smash conquered under its working title. It is the single best argument that the modern classics era belongs to Europe as much as New York, and the whole recipe fits in one hand.
Southside
Nobody owns the Southside’s origin story, which is half its charm. New York claims it for the 21 Club, the speakeasy where it was the house pour for the well-dressed end of Prohibition; Long Island claims it for the Southside Sportsmen’s Club, where mint from the kitchen garden met gin after the shooting; Chicago claims it for the South Side itself, where mobs allegedly softened harsh bootleg gin with lemon, sugar and mint. All three stories involve gin that needed forgiving and mint that obliged. What emerged is the Mojito’s cooler-headed cousin: gin, citrus, sugar and mint, shaken and strained into a coupe rather than built long over ice. Without soda and crushed ice diluting the frame, the drink is more concentrated and more elegant, the mint reading as perfume rather than salad, the gin’s botanicals and the herb finishing each other’s sentences. It survived Prohibition for the simplest reason: it never needed bad gin to justify itself. With a good London Dry the Southside is one of the finest simple gin sours in the canon, a drink that dresses for dinner where the Mojito dresses for the beach.
