Cuba Libre
A Cuba Libre is 50ml of white rum, 120ml of cola and 10ml of fresh lime juice, built over ice in a highball and stirred once, with the squeezed lime dropped into the glass. About 2.0 UK units. The measures match the IBA’s. It comes from Havana in the early 1900s, after the war with Spain, when bottled American cola began reaching Cuba. The account most often cited is an affidavit sworn in 1965 by Fausto Rodriguez, a Bacardi advertising executive, who said he saw the first one poured in August 1900. Given who employed him, it is a claim worth weighing rather than a record. The name was the independence slogan: free Cuba. The lime is what separates it from a Rum and Coke. Cola is sweet and low in acid, and 10ml of lime gives the drink an edge and a dry finish.
Glassware: Highball Glass
Garnish: Lime shell spent, in the glass
Ingredients
50ml
At 40% ABV, in the Havana style: light and dry, with enough cane character to be heard through the cola. An aged rum makes a richer, slower drink.
120ml
Cold and freshly opened. At 120ml it is most of the glass, so a cola with some bite and bitterness behind the sugar makes a firmer drink than a flat, sweet one.
10ml
Squeezed into the glass from a lime cut the same day. It is what makes the drink a Cuba Libre rather than a Rum and Coke.
Instructions
Fill a highball glass with cubed ice.
Squeeze 10ml of fresh lime juice into the glass and drop the spent lime piece in.
Add the rum and top with the cold cola.
Stir once, gently.

Expert Tip
Squeeze the lime into the glass and drop the spent piece in after it. The juice gives the acid; the peel oil sits on the surface and reaches the nose first. Fill the glass with ice and chill the cola. A half-filled glass melts and warms faster, and a warm Cuba Libre tastes of sugar. Stir once, gently. The lime only needs lifting through, and more stirring knocks the fizz out of the cola.
Behind the Cuba Libre
Flavour Profile
Where It Comes From
Havana, in the early 1900s. The war of 1898 had ended Spanish rule, American troops were on the island, and bottled cola began arriving from the United States in 1900. Rum, cola and lime met in the city’s bars.
The account most often cited is Fausto Rodriguez’s. In a 1965 affidavit he said that in August 1900, as a young messenger, he watched an American Signal Corps officer order Bacardi with Coca-Cola, and the soldiers nearby order a round. Bacardi ran the affidavit as an advertisement in 1966, and Rodriguez worked for the company, so treat it as a claim.
The Lime
The lime is what separates the Cuba Libre from a Rum and Coke.
Cola is sweet and low in acid. Ten millilitres of lime cuts the sugar and dries the finish, and the spent piece dropped into the glass adds peel oil to the surface of the drink.
The Rum
White rum is the IBA’s choice and the Havana style: light and dry, so the cola and lime stay in front. It needs some cane character, or the glass tastes of cola alone.
An aged rum makes a darker, slower drink, with caramel and dried fruit under the cola. It is a different drink rather than a better one; the choice is about the hour.
The Cola
At 120ml the cola is most of the glass. One with some bite and bitterness behind its sugar makes a firmer drink; a flat, sweet one leaves the lime working harder.

How to Serve It
Tall, cold and straight away: a highball full of ice, one gentle stir, and no garnish beyond the lime already in the glass.
It builds in seconds, so make it glass by glass for a group rather than batching it; cola poured ahead goes flat.
Without the lime it is a Rum and Coke; with tequila and a salted rim, a Batanga.

The Spirit
White RumWhite rum is clear rum, usually bottled at 40% ABV, either unaged or rested in oak and then charcoal-filtered back to clear. It is the light, dry rum of the Daiquiri, the Mojito and the Cuba Libre, and the rum most of our recipes mean when they want rum that sits under lime rather than over it.

Dark ’n’ Stormy
A Dark ’n’ Stormy is 60ml of Gosling’s Black Seal rum floated over 100ml of ginger beer in a highball full of ice, with a lime wedge. About 2.4 UK units. Those are the IBA’s measures, and the name is a Gosling Brothers trade mark tied to Black Seal. Gosling Brothers say the drink was first mixed in Bermuda just after the First World War. The usual story puts ginger beer from a Royal Navy officers’ club with the local black rum, and a sailor is said to have called the colour that of a cloud only a fool or a dead man would sail under. Gosling’s has held a US registration on the name since 1991 and uses it to stop the drink being sold under that name with any other rum. The same build with another dark rum is a rum and ginger beer, and a sound one.
Storm & Spice
Storm & Spice is 50ml of Expedition Spiced Rum floated over 150ml of ginger beer and 15ml of fresh lime juice in a highball full of cubed ice, with two dashes of Angostura on top, a lime wedge and crystallised ginger. About 2.0 UK units from the rum at 40% ABV; the bitters add less than 0.1. It is our spiced-rum answer to the Dark ’n’ Stormy, the Bermudian highball of black rum and ginger beer. That name is a Gosling Brothers trade mark tied to their Black Seal rum, so this is a different drink on the same frame. A black rum brings weight and dark sugar. Expedition Spiced Rum brings vanilla, cinnamon and clove, which gives the ginger more to catch hold of. The build is the point. Ginger beer goes in first, then the rum is poured slowly over the back of a spoon so it sits dark over the pale ginger. Left layered, the first sips lead with rum. Stirred, the two run together.
Mojito
A Mojito is 45ml of white rum, 20ml of fresh lime juice, two teaspoons of white cane sugar and six sprigs of mint, built in a highball. The mint is pressed gently with the sugar, the glass is filled with cubed ice, the rum and lime go in, and 75 to 100ml of chilled soda water tops it. About 1.8 UK units. Those are the IBA’s measures. The IBA only says to top up with soda, so the 75 to 100ml is ours. Press the mint once or twice and stop. Torn leaves make the drink bitter and grassy, and that, more often than the rum, is why a Mojito disappoints. The sugar grains help: they bruise the surface of the leaf as you press, and the lime then carries the oil through the glass.
