Nuclear Daiquiri
The Nuclear Daiquiri is a daiquiri with the base split between overproof Jamaican rum and green Chartreuse, and there is no sugar syrup in it at all. Ten millilitres of falernum is the entire sweet register, which is not much against forty-five millilitres of two of the loudest liquids on any back bar. Gregor de Gruyther built it at LAB in London around 2005. The name was accurate rather than clever: Wray & Nephew at 63 per cent and Chartreuse at 55 make a drink that is genuinely strong, and the colour that comes out of the shaker is a green-gold that looks like a warning. What makes it a modern classic rather than a dare is that it is properly balanced. The rum's ester funk and the Chartreuse's herbs are so loud that they cancel rather than compete, the falernum's clove translates between them, and a full measure of lime holds the whole thing inside a sour's structure. The result is improbably harmonious. It is also one per evening.
Glassware: Coupe Glass
Garnish: None: the colour is the warning label
Ingredients
25ml
Wray-strength Jamaican, and the esters are structural rather than incidental. The funk is what gives the Chartreuse something of equal weight to push against; a clean overproof leaves the herbs unopposed.
20ml
The other half of the base rather than a modifier, at a hundred and thirty botanicals and 55 per cent. Green rather than yellow: yellow is softer and sweeter and the drink stops being what it is.
10ml
Ten millilitres, and the entire sweet register. It brings clove, ginger and lime along with the sugar, which is why the recipe refuses plain syrup outright.
25ml
A full daiquiri measure holding two very loud spirits inside a sour's structure. It is the only thing in the glass doing an ordinary job.
Instructions
Add the overproof rum, green Chartreuse, falernum and lime juice to a shaker.
Fill with cubed ice and shake very hard for 12 seconds.
Double strain into a chilled coupe.
Serve without garnish.
Expert Tip
No sugar syrup, and this is the one rule the drink actually has. Ten millilitres of falernum is all the sweetness there is, and it arrives with clove, ginger and lime attached rather than as bare sugar. Add syrup and you soften a drink built specifically to refuse softening, at which point it is a strong daiquiri with Chartreuse in it. Use a proper Jamaican overproof. Wray & Nephew is the reference and the esters are structural: the funk is what gives the Chartreuse something of equal weight to push against. A clean overproof leaves the herbs unopposed. Shake it very hard. Two high-proof spirits and only twenty-five millilitres of lime need real dilution, and an under-shaken one is hot rather than bright.
Flavour Profile
Where It Comes From
Gregor de Gruyther built the drink at LAB in Soho around 2005. LAB was one of the bars that defined London's cocktail revival, and this was its after-hours drink: the thing the staff made for each other once the room had emptied.
It spread through the trade first and the public afterwards, which is the usual route for a drink like this. De Gruyther died in 2009, young, and the Nuclear Daiquiri has since become the thing he is remembered by. It is one of the small number of drinks from that London decade now poured internationally without anyone needing to explain where it came from.
Two Spirits That Should Not Work
Overproof Jamaican rum and green Chartreuse both dominate anything they are put near. Wray & Nephew is 63 per cent and tastes of banana, glue and overripe fruit, which is the ester character Jamaican pot stills produce. Chartreuse is 55 per cent and tastes of a hundred and thirty things at once.
Put either in a drink with something quieter and it takes over. Put them together at twenty-five and twenty millilitres and something odd happens: neither can dominate, so they occupy the same space and come out as one flavour rather than two. The funk reads herbal and the herbs read fruity, and the drink tastes like neither bottle does alone.
Why There Is No Syrup
Falernum is a Barbadian liqueur made with lime, clove, ginger and almond, and it is sweet without being only sweet. Ten millilitres of it carries a good deal of flavour alongside the sugar.
That matters here because the drink has no room for a plain sweetener. Sugar syrup would round the edges, and the edges are the drink: a Nuclear Daiquiri that has been softened is simply a strong daiquiri with a herbal note in it. The falernum's clove and ginger sit between the rum's funk and the Chartreuse's herbs and act as a translator, which plain sugar cannot do.
How Strong It Actually Is
Forty-five millilitres of spirit at an average of around 59 per cent is a great deal of alcohol for a coupe. A standard daiquiri is sixty millilitres at 40. This contains roughly a third more alcohol in a smaller glass.
The reason it needs saying is that it does not taste like it. The lime and the falernum keep it bright, the shake dilutes it properly, and it goes down like a daiquiri. That is the entire hazard. One per evening is the convention in the trade and it is a sensible one.
How to Serve It
Shaken very hard for twelve seconds, double strained into a chilled coupe, and served without garnish.
There is nothing you could put on it that would improve it, and the colour is the presentation. If somebody is meeting it for the first time, tell them what is in it before they drink it rather than afterwards.
The Spirit
Overproof RumRum bottled well above standard strength, typically from 57% upward and occasionally past 75%. It is used in millilitres rather than measures, and it is the one bottle on the shelf that presents a genuine fire risk.
Frequently Asked Questions
What is a Nuclear Daiquiri?
A daiquiri with the base split between overproof Jamaican rum and green Chartreuse, sweetened only with falernum and no sugar syrup. Gregor de Gruyther built it at LAB in London around 2005, and the name is a description rather than a joke.
How strong is it?
Genuinely strong. Forty-five millilitres of spirit averaging around 59 per cent, which is roughly a third more alcohol than a standard daiquiri in a smaller glass. It does not taste like it, which is the point of the warning.
Why is there no sugar syrup?
Because the falernum is the sweetness, and it brings clove, ginger and lime with it rather than bare sugar. Plain syrup would round off the edges, and the edges are what the drink is. Softening it produces something else.
Can I use yellow Chartreuse?
You can, and it makes a much gentler drink. Yellow is lower in proof, sweeter and honeyed rather than herbal, so it stops standing up to the overproof rum. The result is pleasant, and it is not this recipe.

Daiquiri
The Daiquiri is a sour in its most elemental form: white rum, fresh lime juice and sugar syrup, shaken and served up. Three ingredients, no bitters, no liqueur, nothing to hide behind. It takes its name from a mining district on the south-eastern coast of Cuba, near Santiago, where Jennings Cox, an American mining engineer, is credited with combining local white rum with lime and sugar around 1898. Whether Cox invented it or documented what Cuban workers had been drinking for years is not something the record can resolve. What is not disputed is that it was refined and popularised in Havana at El Floridita by Constantino Ribalaigua Vert. The simplicity is the point and the problem at once. There is nothing in the construction to compensate for a poor rum, juice that was not squeezed fresh, or a syrup made carelessly. Every variable is fully exposed, which is why a properly balanced Daiquiri demonstrates more skill than a ten-ingredient tiki drink.

Zombie
The Zombie was created by Donn Beach at Don the Beachcomber in Hollywood in 1934 and became the most infamous drink in the tiki canon almost immediately. Beach kept the recipe encoded for decades, forcing rivals into inferior imitations that gave the Zombie its reputation for being more alcohol than intention, and the original was not reconstructed with confidence until Jeff Berry published Sippin' Safari in 2007. Beach called it a mender of broken dreams and limited his customers to two per sitting. Both descriptions remain accurate. The official build splits three rums across the palate rather than stacking four: Jamaican for aroma and fruit, gold Puerto Rican for body through the middle, and Demerara for smoke and weight underneath. Lime, falernum and a dash of grenadine frame them. What makes it the Zombie rather than a rum punch is Donn's Mix, which is grapefruit juice cut with cinnamon syrup, and six drops of Pernod. Both were part of the coded recipe, both were missing from every version poured between 1934 and 2007, and their absence is exactly why the drink spent seventy years with a reputation for brute strength.

Last Word
The Last Word is one of the great equal-parts cocktails: gin, green Chartreuse, maraschino liqueur, and fresh lime juice in identical measures, shaken and served up. No component leads and no component follows. Each of the four is assertive enough to dominate a lesser recipe, and the fact that none dominates this one is the drink’s central achievement. It originated at the Detroit Athletic Club around 1915, documented by Ted Saucier in his 1951 book Bottoms Up and attributed to vaudeville performer Frank Fogarty, who allegedly introduced it to the club. It disappeared almost entirely during and after Prohibition and was rediscovered in the early 2000s by Seattle bartender Murray Stenson, who found it in Saucier’s book and put it on the menu at the Zig Zag Café. From there it spread through the craft cocktail world and has not left. The revival was deserved. Green Chartreuse brings herbal intensity, maraschino brings cherry sweetness and a faint bitter almond note, fresh lime brings tartness, and gin holds it together. Each sip reveals a different component leading depending on where in the glass you are. It is a drink worth paying attention to.
