How to Make Irish Coffee and Irish Mist Coffee

If you’ve ever craved a warm, boozy lift after being out in the cold—or just wanted to recreate that cozy pub feeling at home—you’ve likely wondered how to make a proper Irish Coffee. It’s not a shot of whisky in black coffee, nor is it a latte with booze. There’s a precise formula behind the original drink, and its close cousin, Irish Mist Coffee, that balances heat, sweetness, alcohol, and texture perfectly.

To make the classic Irish Coffee, you need 150cc of medium-dark roasted coffee, 20cc of Irish whiskey, 10g of white sugar, and 20cc of lightly whipped cream—poured gently so it floats. For Irish Mist Coffee, substitute the whiskey with 20cc of Irish Mist liqueur, made with Irish whiskey, honey, and vanilla.

What Is Irish Coffee?

Irish Coffee is a warm, spirited coffee drink that originated as a way for fishermen to ward off the cold after long days at sea. Though it gained global fame later at a San Francisco café, its roots are firmly Irish. The drink combines strong coffee, a measure of Irish whiskey, sugar, and a float of cream—all assembled carefully for the right balance of heat, bitterness, alcohol, and richness.

The Classic Irish Coffee Recipe (Step by Step)

Making a true Irish Coffee isn’t just about throwing ingredients together. Here’s the exact method:

• Heat your glass or mug (traditionally thick and handled) until hot, then wipe it dry.
• Add 10g of white granulated sugar to the base of the cup.
• Pour in 20cc of Irish whiskey.
• Add 150cc of medium-dark roasted coffee (not espresso). The coffee should be freshly brewed and still hot.
• Stir gently to dissolve the sugar.
• Top with 20cc of lightly whipped cream. Pour it over the back of a spoon so it floats on top. Do not stir after adding the cream if using dairy cream. If using fresh whipped cream, avoid mixing it in with a spoon.

What About Irish Mist Coffee?

Irish Mist Coffee is a variation that swaps out the whiskey for Irish Mist—a liqueur made with Irish whiskey, honey, and vanilla. It has a slightly sweeter, more aromatic profile thanks to the honey and botanicals in the mist.

The recipe follows the same structure:

• Warm and dry your cup.
• Add 10g of white sugar.
• Pour in 20cc of Irish Mist.
• Add 150cc of medium-dark coffee.
• Stir to dissolve the sugar.
• Float 20cc of lightly whipped cream on top. Again, no stirring once the cream is added.

The combination of coffee, cream, and the honey-vanilla warmth of the Irish Mist creates a smoother, more dessert-like drink compared to the drier kick of straight whiskey in the original.

Why These Ratios Matter

The specific measurements in both drinks are essential for balance:

• 150cc of coffee provides a strong but not overpowering base.
• 20cc of spirit (whiskey or Irish Mist) gives enough alcohol warmth without dominating.
• 10g of sugar balances the bitterness of the coffee and the booziness.
• 20cc of cream adds a luxurious mouthfeel and tempers the heat and bitterness.

Deviating from these proportions—especially skimping on sugar or over-whipping the cream—can throw off the intended texture and flavor harmony.

How to Float Cream Properly

One of the trickiest parts of both drinks is getting the cream to float neatly on top. Here’s how to do it right:

• Use cold, lightly whipped cream—soft peaks, not stiff.
• Pour it over the back of a spoon held just above the surface of the coffee mixture.
• Let it drift down and rest on top without sinking or mixing in.
• Do not stir after pouring the cream—it’s meant to be sipped through the cream for contrast.

This technique ensures the hot coffee and alcohol remain underneath while the cool, silky cream sits on top, creating a contrast of temperatures and textures in every sip.

Frequently Asked Questions

Can I use espresso instead of regular coffee in Irish Coffee?

No, the traditional Irish Coffee recipe calls for 150cc of regular medium-dark brewed coffee—not espresso. Using espresso will concentrate the bitterness and alter the balance meant for this drink. The coffee should be hot, freshly brewed, and smooth enough to complement the whiskey and cream.

What kind of cream should I use for the float?

Use lightly whipped heavy cream—about soft peaks. You can also use store-bought whipped cream, but avoid over-whipping. For the traditional version, dairy cream is floated on top and not stirred in. If using fresh cream, do not mix it with a spoon after pouring.

Is Irish Mist the same as Irish whiskey?

No. Irish Mist is a liqueur made with Irish whiskey, honey, and vanilla. It’s sweeter and more aromatic than straight whiskey. In Irish Mist Coffee, it replaces the whiskey and gives the drink a smoother, slightly sweeter profile with honey and vanilla notes.

Do I stir the cream into the drink?

No. Once the cream is floated on top, it’s meant to be left undisturbed. The drink is designed to be sipped through the cream, which contrasts with the hot, boozy coffee beneath. Stirring ruins the texture and temperature contrast.

Can I make Irish Coffee with any type of alcohol?

Traditionally, Irish Coffee uses Irish whiskey. Substituting other spirits will change the flavor profile significantly. Irish Mist Coffee specifically uses Irish Mist liqueur, which includes honey and vanilla. For an authentic experience, stick to the original spirits.
