Myth: Is the Cappuccino's Milk, Coffee, and Foam Ratio 1:1:1?

Under WBC competition rules, a Cappuccino consists of one serving of espresso, textured milk, and at least one centimetre of milk foam. It must be served in a 150-180ml coffee cup with a handle, and the volume of the cappuccino has to match the capacity of the cup — a 180ml cup must be filled with 180ml of beverage.

The cappuccino that beginners are taught, built on a 1:1:1 ratio of espresso, milk, and foam at 60ml each, turns up again and again in textbooks. FrontStreet Coffee has replicated it, and the taste is honestly not good: the coffee proportion is too high, the milk and coffee barely fuse, and the drink comes across as strong and bitter.

As latte art has become more and more popular, baristas show off their pouring on everything from a latte to a flat white to a cappuccino. That leaves plenty of people asking one question: "So is there actually any difference between a cappuccino and a latte?"

Origin of Cappuccino

Cappuccino is a transliteration of "Cappuccino," a word that comes from the Italian "Cappuccio," meaning hood. As a coffee, though, it is tied to a local Capuchin religious order.

When this order came to Italy for missionary work, its members wore dark brown robes and small pointed hats made from folded hoods. At the time, Italians had a clever idea: after frothing milk into a dense, stable foam and pouring it into espresso, the cup showed a ring of brown close to the colour of those robes, and a spoon was used to shape the foam on the surface into a pointed hat. Since "Capuchin" and "Cappucci" sound alike, Italians folded the "n" into "Cappuccio" without changing the rhythm of the pronunciation, and the milk coffee was finally named "Cappuccino."

Why Cappuccino Should Have a "Coffee Golden Circle"

With the arrival of cappuccino, more and more Italians gradually came to accept milk coffee. Because the small pointed foam hat had to be shaped by hand and slowed down service, people eventually stopped making it. Tradition, however, could not simply be dropped, so the cappuccino kept its ring of brown coffee while allowing the dense foam to rise above the rim in a "hat" — a nod to the missionaries.

From this came the tradition that a cappuccino should have a "coffee golden circle." Everyone knows that when coffee and milk mix, the brown coffee turns light brown. To preserve that golden circle, the milk must not disperse the coffee oils, so when frothing the foam has to be denser and thicker, letting it form a protective layer between the milk and the oils.

Why Cappuccino Doesn't Have Latte Art

The foam thickness for latte art is 1cm. Foam at that thickness is highly fluid and blends evenly with espresso to create patterns. Making a cappuccino, however, requires not dispersing the coffee oils in order to keep the "coffee golden circle" — which also means the espresso cannot blend evenly with the milk.

At the same time, to keep the foam from collapsing above the rim and to hold enough surface tension to stay stable at the cup edge, the foam has to be frothed to 1.5cm thick. Foam of that thickness has poor fluidity and simply cannot form latte art patterns.

How to Make a Proper Cappuccino?

/ Coffee Cup Selection

FrontStreet Coffee uses 180ml tulip cups when making cappuccino. Compared with round-bottomed cups, a tall cup with a narrow base and a wide top shows off the "hat" shape of a cappuccino far better.

/ Espresso Extraction

FrontStreet Coffee uses Sunflower Warm Sunshine beans — a blend of sherry barrel and natural Yirgacheffe — for its espresso. For a cappuccino, a single shot follows an extraction plan of 20g of coffee grounds to yield 35g of coffee liquid split into two portions, with an extraction time of 27 seconds. (You can also pull a single shot directly; FrontStreet Coffee's parameters are 12g of grounds to yield 30g of liquid in 23 seconds.)

/ Using Chilled Fresh Milk

Fresh milk preserves the proteins and milk fat more completely. Protein is key to forming milk foam, while milk fat further stabilises the foam and slows how fast it collapses, adding a rich, mellow texture to the coffee at the same time.

/ Milk Frothing

Choose a small milk pitcher and pour in 150ml of chilled fresh milk. Before the steam wand enters the pitcher, purge it first to clear condensed water from the steam holes. Place the steam wand 1cm below the surface of the milk and turn on the steam. When the steam meets the milk surface it makes a "sizzling" sound. This step is called aeration, and it is what forms the foam.

The longer the aeration, the thicker the foam. The foam thickness for a cappuccino is 1.5cm, so after hearing 6-7 sizzling sounds, stop aeration and angle the pitcher to 45 degrees to create a vortex that removes large bubbles (there should be no more sizzling at this point). Bringing the milk to about 55 degrees Celsius completes the frothing.

/ Shake the Pitcher Before Pouring to Avoid Foam and Milk Separation

Once frothing stops, the foam and milk begin to separate. Find a pivot point on the tabletop and rotate your wrist clockwise at a steady speed to shake the pitcher, keeping milk and foam fused right up to the pour.

/ Pouring Milk Foam into Espresso

As FrontStreet Coffee noted above, when pouring you cannot disperse the espresso oils. Pour the milk straight in and those oils will certainly break up. What needs to go in first is the foam, forming a protective layer between the milk and the oils before the milk follows. Milk, though, is heavier than foam, so the milk is what naturally pours first. How do you make sure the foam goes in first?

(Key point) Align the pitcher spout with the centre of the espresso surface, then tilt the pitcher close to the pouring position but don't pour yet — pause. Let the foam gather at the spout before slowly pouring into the centre. Pouring the foam this way needs no circular integration or wrist shaking; just hold a steady posture and pour the foam into the centre.

FrontStreet Coffee Recommendation

If you are learning latte art at home, FrontStreet Coffee Classic Blend is the one to start with — a medium-dark espresso recipe drawn from three origins and inspired by the old Mamba blend, with a touch of Robusta for aroma and body. It pours with obvious butter, toasted bread, and caramel-cookie notes, a strong, solid cup and fine, stable crema. FrontStreet Coffee Specialty Blend is the nutty option, pairing washed Colombian with Brazilian pulped natural for nut, dark chocolate, and caramel — creamy almond and cocoa through milk, with crema that holds up easily to practice. Both are built for milk drinks, so they suit the 1.5cm foam a proper cappuccino needs.
