Dublin Mule
A Dublin Mule is 50ml of Irish whiskey, 20ml of fresh lime juice and 15ml of simple syrup built over ice in a copper mug or highball, topped with 90ml of ginger beer and stirred gently. A mint sprig and a lime wheel go on top. About 2.0 UK units. It is the Moscow Mule with Irish whiskey in place of vodka, and it has no documented inventor or date. Vodka disappears behind the ginger; a light Irish blend stays in view, adding grain sweetness and a soft fruit note. There is little technique to it. A fiery ginger beer and lime squeezed the same day decide how it turns out, and the syrup adjusts for how sweet the ginger beer is.
Glassware: Copper Mug
Garnish: Mint sprig slapped to wake the aroma and Lime wheel perched on the rim
Ingredients
50ml
A blended Irish whiskey at 40% ABV. Its light body stays present under the ginger where vodka would vanish. A heavily sherried or peated whiskey takes the drink over.
20ml
Squeezed the same day. It is the only acid in the glass, and the link between the whiskey’s grain and the ginger’s spice.
15ml
Sugar and water, 1:1 by weight. A dial rather than a fixture: the full 15ml for a dry ginger beer, about half for a sweet one.
90ml
Cold, with real ginger heat. The heat comes from here; a soft, sweet bottle leaves the drink flat. Ginger ale makes a different, milder drink.
Instructions
Squeeze the lime juice the same day, ideally just before you build.
Fill a chilled copper mug or a highball glass with ice.
Add the Irish whiskey, lime juice and simple syrup.
Top with the ginger beer and stir gently.
Garnish with a slapped mint sprig and a lime wheel.
Expert Tip
Taste the ginger beer before you build. Brands vary widely in sweetness and heat. A dry, fiery one wants the full 15ml of syrup; with a sweet one, halve the syrup or leave it out, or the drink turns sticky. Use lime squeezed that day. At 20ml it is the only acid in the glass, and it ties the grain of the whiskey to the spice of the ginger. Pour the ginger beer last and stir once or twice from the bottom. A copper mug chills fast, so put it in the fridge first: it warms just as quickly in a hand.
Behind the Dublin Mule
Flavour Profile
Where It Comes From
The Dublin Mule is the Moscow Mule with Irish whiskey where the vodka was. The mule format of spirit, lime and ginger beer takes a change of spirit easily, and the family now has versions for most bottles on a back bar.
No bartender or bar is recorded as having created this one, and it has no documented date. Its place on St Patrick’s Day comes from the whiskey and the mint, not from Dublin history.
Why the Whiskey Works
Vodka is in a Moscow Mule to add strength and vanish. Irish blends are generally light and soft, so the whiskey stays present under the ginger beer without fighting it. The 50ml measure is generous for a mule, deliberately: pour less and the ginger covers it.

Lime, Syrup and Ginger Beer
The lime links grain and spice, and at 20ml it is twice the Moscow Mule’s measure, because the whiskey’s sweetness needs more acid than vodka does. The syrup is there to balance whichever ginger beer you have, so set it by taste. The ginger beer carries the heat the whiskey does not.
Running It for a Table
A bottle of Irish whiskey makes fourteen at 50ml each. Combine the whiskey, lime and syrup in a jug that morning and chill it; each glass then needs only ice, 85ml of base and the ginger beer.
Keep the ginger beer out of the jug. Opened and left standing, it goes flat, and there is no getting the bubbles back.
How to Serve It
Over ice in a chilled copper mug or a highball, stirred gently once the ginger beer is in, with a lime wheel and a mint sprig, slapped first, on top. Serve it cold and straight away.
The vodka original, with less lime and no syrup, is the Moscow Mule.

The Spirit
Whiskey (Irish)Irish whiskey is whiskey distilled on the island of Ireland and aged there in wood for three years or longer, and bottled at no less than 40% ABV. It comes in four legal types, pot still, malt, grain and blended, and the soft blends are what our nine Irish recipes mostly use. Triple distillation and the absence of peat are common habits, not legal requirements.

Moscow Mule
A Moscow Mule is 45ml of vodka and 10ml of fresh lime juice over ice in a copper mug, topped with 120ml of cold ginger beer and stirred once, with a lime wedge. Those are the IBA’s measures. About 1.8 UK units, all from the vodka. It is usually dated to 1941 and credited to John G. Martin, who was trying to sell Smirnoff vodka to Americans who did not drink it, and Jack Morgan of the Cock ’n’ Bull in Los Angeles, who had ginger beer he could not shift. Other accounts put the first one in a New York hotel bar, or credit the Cock ’n’ Bull’s bartender. The ginger beer decides the drink. At 120ml it is two thirds of the glass, so a soft, sugary one gives a soft, sugary Mule. Use the fieriest you can find, and keep the lime short: good ginger beer brings its own bite.
Irish Maid
An Irish Maid is 50ml of Irish whiskey, 25ml of elderflower liqueur and 25ml of fresh lemon juice, shaken hard with four slices of pressed cucumber and double strained over fresh ice in a rocks glass, with a cucumber ribbon. About 2.5 UK units. The elderflower liqueur is the only sweetener. It is the Irish whiskey branch of the Maid family. Sam Ross made the first, the Kentucky Maid, at Milk & Honey in New York in about 2005: bourbon, lime, sugar syrup, mint and cucumber. Change the base and the name follows, so gin makes an Old Maid. One widely printed Irish Maid is credited to Jack McGarry of The Dead Rabbit, also in New York; who poured the first is not settled. Ours leaves out the sugar syrup that most versions carry and lets 25ml of elderflower do the sweetening. That keeps the drink drier and puts the flower in front, with the cucumber cooling the finish and the lemon holding it in line.
Jamaican Mule
A Jamaican Mule is 50ml of spiced rum, 12.5ml of fresh lime juice and 7.5ml of rich sugar syrup stirred briefly in a copper mug, filled two thirds with cubed ice, topped with 75ml of ginger beer and capped with a crown of crushed ice, with a lime slice and a bouquet of mint. About 2.0 UK units from a rum at 40% ABV. The name says Jamaica. The recipe does not. The specification calls for spiced rum, not a Jamaican pot-still rum, and nobody is recorded as having created or named it. It is the drink most people mean when they ask for a spiced rum mule: a Moscow Mule with the vodka swapped for a rum that already carries vanilla, cinnamon and clove, so the ginger beer meets the spice instead of covering it. It is shorter than it looks. At 75ml the ginger beer is half the glass rather than two thirds, and the lime and rich syrup sit under it as a small sour. Taste the ginger beer first: a dry, hot one wants the full syrup, a sweet one wants none.
