What Is a Cappuccino and How Is It Made?

If you’ve ever ordered a cappuccino and wondered why it looks like a short drink with a fluffy top, you’re not alone. Many coffee drinkers are unclear on what truly defines a cappuccino—how much milk, how much foam, and why it’s different from a latte or flat white. This guide breaks down the facts, the history, and how to make one properly at home.

A traditional cappuccino consists of equal parts espresso, steamed milk, and milk foam—each making up one third of the drink. That’s a 1:1:1 ratio. A standard small cappuccino (240cc) contains around 75mg of caffeine, regardless of size, since the milk doesn’t change the coffee dose.

Where the Name 'Cappuccino' Comes From

The name 'cappuccino' comes from the Capuchin friars, a Catholic order founded in 1525. Their brown habits and pointed hoods reminded Italians of the color and shape of the drink: dark espresso with a light-colored foam 'hood.' The Italian word 'cappuccio' means hood, and over time, the drink took on the same name due to this visual resemblance.

What Makes a Cappuccino Different?

Unlike a latte—which is mostly steamed milk with a small amount of foam—or an Americano, which is just diluted espresso, the cappuccino is defined by its balance. It’s made with one shot of espresso (about 30ml), an equal amount of steamed milk, and an equal amount of thick milk foam. This creates a drink that’s stronger in flavor than a latte but creamier than espresso alone.

Traditional cappuccinos are served without latte art. Instead, baristas may sprinkle cocoa powder, cinnamon, or citrus zest on top of the foam for added aroma. At Starbucks, cappuccinos are often finished with a spoonful of foam placed on top rather than integrated throughout.

The Standard Formula: Coffee, Milk, Foam

A classic cappuccino uses:

• 1 shot of espresso (approx. 30ml)
• 1 part steamed milk (approx. 30ml)
• 1 part milk foam (approx. 30ml)

The milk should be freshly steamed to around 60–65°C (140–149°F), creating microfoam that’s smooth and velvety. The foam on top should be thick enough to hold texture and allow for optional toppings.

How to Make a Cappuccino at Home (FrontStreet Method)

FrontStreet Coffee recommends using a classic espresso blend for a balanced cappuccino. Here's how to build one following their home method:

1. Brew the Espresso: Use 20g of finely ground espresso beans. Extract 40ml of coffee in about 32 seconds using a 1:2 brew ratio. This yields a concentrated shot with rich crema.
2. Froth the Milk: Steam fresh milk, aiming for a thick, velvety microfoam. Since you won’t be pouring latte art, make the foam slightly thicker than usual.
3. Assemble the Drink: Pour the espresso into your cup first. Then use a spoon to place a dollop of foam in the center to build a base. Next, tilt the cup and pour the steamed milk through the center, allowing the foam to rise to the top naturally. Fill to about 11/10 capacity.

For best results, FrontStreet suggests using their Specialty Blends like Strawberry Candy Espresso for fruity complexity or Grana Geisha for a bright, clean profile. Alternatively, Black Cocoa Blend offers a rich, chocolatey base perfect for a classic cappuccino.

Cappuccino Caffeine Content

A standard small cappuccino (240cc or one shot of espresso) contains approximately 75mg of caffeine. A medium (360cc, still typically one shot) also has about 75mg, while a large cappuccino (480cc, often with two shots) may contain around 150mg. Caffeine levels are based on the espresso shot, not the milk. Low-caffeine versions can be made using decaf beans that remove 98% or more of the caffeine content.

Frequently Asked Questions

What’s the difference between a cappuccino and a latte?

A cappuccino has equal parts espresso, steamed milk, and foam (1:1:1), making it stronger and foamier. A latte is mostly steamed milk with a small amount of foam, usually around 1/6 espresso, 4/6 steamed milk, and 1/6 foam.

How much caffeine is in a cappuccino?

A small cappuccino (240cc) with one shot of espresso contains about 75mg of caffeine. Medium (360cc) and large (480cc) sizes often still use one shot, maintaining 75mg—though larger versions with two shots may reach 150mg.

Can I make a cappuccino without a coffee machine?

Technically yes, but you’ll need an espresso alternative (like a Moka pot or AeroPress) and a way to steam milk. Without a proper espresso machine and steam wand, replicating the exact texture is difficult, though similar drinks can be made.

What kind of milk is best for cappuccino?

Whole milk is ideal for cappuccinos because it froths well and creates a rich, creamy foam. However, skim or plant-based milks can be used—they just may require more effort to get stable foam.

Why is my cappuccino foam not thick enough?

Thick foam requires milk to be heated to around 60–65°C and steamed with steady motion to incorporate air without overheating. Using fresh cold milk and a good steam wand helps achieve microfoam suitable for cappuccinos.
