Cappuccino Explained
A cappuccino is an espresso-and-milk drink traditionally known for a compact serving size, pronounced milk foam, and a stronger coffee-to-milk balance than a large latte. The exact recipe has changed across countries and decades, so the familiar “one-third espresso, one-third milk, one-third foam” rule is better understood as a teaching shorthand than a universal modern standard.
What makes a cappuccino a cappuccino?
In contemporary specialty coffee, a cappuccino commonly uses one or two espresso shots with smoothly textured milk in a cup around 5–6 oz, though cafés may serve larger or smaller versions. The milk should be integrated and glossy rather than separated into hot liquid milk topped by a stiff layer of dry bubbles.
Cappuccino vs. latte vs. flat white
| Drink | Typical size | Milk texture | Coffee intensity |
|---|---|---|---|
| Cappuccino | Often 5–6 oz | More aerated, still glossy | Strong |
| Latte | Often 8–12+ oz | Thin microfoam | Milder because of more milk |
| Flat white | Often 5–8 oz | Fine integrated microfoam | Coffee-forward |
| Cortado | Often 4–5 oz | Lightly textured milk | Very coffee-forward |

How much air should be added?
A cappuccino usually has more aeration than a flat white, but modern cappuccino foam is still microfoam: tiny bubbles distributed through the milk rather than a dry spoonable cap. Start aeration early, then submerge the steam tip slightly and create a rolling vortex to refine the bubbles.
The milk should look glossy, flow like wet paint, and pour as one integrated liquid. Our milk steaming guide covers the technique in more detail.
A simple home recipe
- Pull a balanced double espresso, such as 18 g in and 36 g out as a starting point.
- Steam enough milk for a 5–6 oz cup, adding slightly more air than you would for a flat white.
- Swirl the espresso and milk pitcher to keep both homogeneous.
- Pour steadily, allowing the textured milk to integrate with the espresso and finish with a visible white surface.
There is no need to chase a specific foam depth if the drink tastes balanced. Cup size, espresso dose, and roast style all change how much milk works best.
Which coffee works well?
Espresso blends and medium-to-medium-dark roasts with chocolate, caramel, nut, or ripe-fruit notes are classic choices because they remain clear through milk. Lighter roasts can make excellent cappuccinos too, but they may require a higher extraction and slightly less milk to preserve their character.
