Classic Irish Coffee Recipe

Steps

1. Preheat the heatproof glass with hot water, then empty and dry it.
2. Add 8–10 g of brown or demerara sugar to the warm glass.
3. Pour in 120–150 ml of freshly brewed hot coffee and stir until the sugar dissolves.
4. Add 40 ml of Irish whiskey and stir once more.
5. Lightly whip 30 ml of cold double cream until it thickens but remains pourable.
6. Hold a spoon just above the coffee and slowly pour the cream over its back.
7. Serve immediately without stirring the cream into the coffee.

Irish Coffee Ingredients

For one drink, use:

• 120–150 ml freshly brewed hot coffee;
• 40 ml Irish whiskey;
• 8–10 g brown or demerara sugar;
• 30 ml cold double cream, lightly whipped.

Use a clean, balanced filter coffee. It needs enough flavour to remain present beside the whiskey, but an extremely dark or bitter brew can make the finished drink harsh. The coffee-to-water ratio calculator can help you scale the coffee before building the cocktail.

How to Make Irish Coffee

Warm the glass first, dissolve the sugar completely in the hot coffee, then add the whiskey. Keep the coffee hot and the cream cold: that contrast helps the cream float and gives the finished drink its characteristic texture.

What Alcohol Is Used in Irish Coffee?

Traditional Irish Coffee is made with Irish whiskey. A 40 ml measure gives the drink warmth and aroma without burying the coffee. Bourbon, Scotch or coffee liqueur will produce a different drink.

Is Irish Coffee a Cocktail?

Yes. Irish Coffee belongs to the family of hot coffee cocktails: coffee is combined with a measured spirit, sweetener and cream to create a deliberately balanced mixed drink. Browse the Coffee Cocktail recipes for other drinks in this category.

How to Float Cream on Irish Coffee

• Chill the cream and the whisk or shaker before starting.
• Whip only until the cream is lightly thickened and still flows from a spoon.
• Hold the back of a spoon close to the coffee surface and pour slowly over it.
• Do not make the cream stiff; thick peaks fall in clumps and break the clean layer.
• Keep the coffee hot so it remains less dense than the chilled cream layer.

The sugar also matters. Fully dissolved sugar slightly increases the density of the coffee, helping the cold cream remain on top.

Alcohol-Free Variation

For an alcohol-free coffee inspired by the classic presentation, dissolve 8–10 g brown sugar in 150 ml freshly brewed coffee and float lightly whipped cream on top. A small amount of alcohol-free whiskey-style syrup can add vanilla and oak notes. This is an Irish Coffee variation, not the classic cocktail, but it preserves the hot-coffee-through-cold-cream experience. For a non-alcoholic black coffee with a similar serving size, try the Americano recipe.

Barista tip

Drink the hot coffee through the cold cream. That temperature and texture contrast is the entire point of the drink.

Troubleshooting

The cream sinks. Chill it, whip it slightly more or pour it more slowly over the back of a spoon.

The drink is too sweet. Reduce the sugar, not the whiskey.

The alcohol dominates. Increase the coffee towards 150 ml or reduce the whiskey slightly.
