Order a “cappuccino” in one café and a “flat white” in the one next door, and you’ll get two drinks that look almost identical: espresso, steamed milk, a bit of foam. Ask the barista what actually separates them and you’ll usually get a shrug. There is a real answer, and it comes down to one thing: the ratio of milk to foam, not the size of the cup.

Cappuccino: equal thirds, thick foam

A proper cappuccino is roughly a third espresso, a third steamed milk, a third foam. That foam should be thick enough to hold its shape when you tilt the cup. Traditionally it’s served in a 150-180ml cup, which is why the cappuccino you get in Riyadh at a big chain in a 350ml paper cup tastes watered down: more milk, same shot, less foam ratio. That is not a cappuccino. It is a latte wearing a cappuccino’s name tag.

The dry, airy foam matters because it changes how the coffee hits your tongue. You taste the espresso first, then the foam cuts through it. Skip the foam and you lose that structure entirely.

Flat white: less foam, more velvety milk

A flat white swaps thick foam for “microfoam”: milk steamed to a wet, velvety texture with almost no visible bubbles. It’s usually built on a double shot in a 150-165ml cup, so the coffee-to-milk ratio is actually stronger than a cappuccino, even though the drink looks softer on top. This is why people who find cappuccino too “foamy” and lattes too “milky” land on flat white as the answer. It sits in the gap between the two.

Australian and New Zealand cafés get credit for standardizing it in the 1980s, and it has become the default “serious coffee drinker” order in specialty cafés across Riyadh and Jeddah over the last five years. If a barista asks “would you like that as a flat white?” when you order a small latte, that’s usually a good sign about the café.

Cortado: half and half, no foam theatrics

The cortado is the simplest of the three: equal parts espresso and steamed milk, no foam layer at all. Spanish in origin (the name means “cut,” as in the espresso is “cut” with milk), it’s served in a small glass, usually 90-120ml. There’s no microfoam art here because there isn’t enough milk texture to make one. It exists purely to soften the acidity and bitterness of the shot without diluting the coffee flavor the way a bigger milk drink does.

If you like your espresso but find it too sharp on an empty stomach, order a cortado before you order a cappuccino. It’s the closest thing to drinking straight espresso while still being kind to your palate.

So which one should you actually order?

Here’s the honest version, not the textbook one. If you want a familiar, foam-forward drink you can sip slowly: cappuccino. If you want the coffee flavor to lead and the milk to just round the edges: flat white. If you basically want espresso with training wheels: cortado. None of them is “better” in the abstract. They’re solving different problems, and a café that makes all three correctly, with three different textures, is a café that actually trains its baristas rather than just running everything through the same steam wand setting.

Next time you’re at a specialty spot, order a cortado instead of your usual. If it tastes like a small, weak latte, now you know why.
