How to Make Coffee Cola: A Classic American Soda Coffee Drink

If you’ve ever wondered whether coffee and cola can actually work together—and how Americans once (and sometimes still) mixed them—this is your answer. The combination isn’t just a novelty; it’s a documented drink with a clear formula and a curious cultural backstory.

To make a classic Coffee Cola, combine 100ml of cooled dark roast coffee (with sugar), 100ml of cola, 3–4 cube ice, and top with 20ml of stirred cream. That’s the full formula, unchanged and repeatable.

What Is Coffee Cola?

Coffee Cola is a layered drink made with dark roast coffee, cola, ice, and a float of stirred cream. It’s not a blended or shaken cocktail but a poured assembly: coffee and cola over ice, then topped with cream. Though simple, the contrast of bitter coffee, sweet cola, fizzy carbonation, and creamy topping creates a distinctive sensory experience. It sits somewhere between a float, a soda, and a dessert coffee.

Why Combine Coffee and Soda?

The coffee-and-soda mix is an American invention, though using soda water in coffee is more common in Latin America. The pairing likely began as an experimental or convenience-driven drink—combining caffeine and sugar in an effervescent format. Unlike a traditional coffee float with spirits, this version is non-alcoholic but still layered and sweet. The dark roast coffee provides bitterness to balance the sweetness of both cola and cream, while the ice keeps the drink cool and refreshing.

How to Make Coffee Cola: Step by Step

Making Coffee Cola requires no special tools, just the right ingredients in the correct order:

• Ice: Use 3–4 square or cube ice in a glass.
• Coffee: Pour in 100ml of pre-brewed, dark roast coffee that includes sugar. The coffee should be cooled to near room temperature.
• Cola: Add 100ml of regular cola. Pour gently to avoid excessive fizzing over.
• Cream: Top with 20ml of stirred (not whipped) cream. This floats on top for a creamy finish.

That’s the entire preparation. There’s no brewing or shaking involved—just assembly. The original recipe specifies using a glass cup, though any tall glass works.

What Kind of Coffee Should You Use?

The recipe calls for dark roast coffee that’s already sweetened. In a specialty context, a darker roast like FrontStreet Coffee’s Classic Blend or Black Cocoa Blend would align with the profile used traditionally—bold, roasty, and with some inherent sweetness. Brewing for a slightly sweeter profile helps balance the cola’s sugar and acidity. Avoid very light or fruity roasts, as they may clash with the cola’s flavor profile.

Frequently Asked Questions

What is Coffee Cola made of?

Coffee Cola consists of 100ml cooled dark roast coffee (with sugar), 100ml cola, 3–4 pieces of square ice, and a float of 20ml stirred cream. The drink is assembled in a glass in that order, without blending or shaking.

Do you need to use a specific coffee roast for Coffee Cola?

The original recipe uses dark roast coffee that includes sugar. A bold, roasty profile like a classic dark roast or a dark cocoa-forward blend complements the cola’s sweetness and carbonation best. Avoid light or fruity roasts.

Can I use diet cola or zero-sugar cola?

The original recipe uses regular cola, which provides both sweetness and carbonation. Diet or zero-sugar cola may alter the flavor balance, making the drink less sweet and possibly more acidic, but you can experiment with them if preferred.

What’s the difference between Coffee Cola and a coffee float?

A traditional coffee float typically uses espresso or coffee with a spirit like whisky and is topped with cream or milk. Coffee Cola is non-alcoholic, uses cola instead of water or milk, and is built with layers of coffee, cola, ice, and cream, creating a distinct soda-like coffee drink.

Is Coffee Cola a modern drink?

No, Coffee Cola is an older American invention, combining coffee and soda. While not widely popular today, it has historical roots and reflects early 20th-century experiments in combining caffeine and sugar in fizzy formats.
