Hot. A cappuccino is a hot drink by definition, and the reason is the foam: milk needs heat to hold a foam, so the thing that makes a cappuccino a cappuccino doesn’t survive being made cold. Iced versions do exist and they’re worth having, but they’re built a different way rather than being the same drink chilled.
Why is a cappuccino served hot?
Because heat is doing structural work, not just making it warm. Steaming forces air into the milk, but as Serious Eats puts it, “it’s not enough that air is introduced; the milk also needs to be heated for that foam to stick around.” The heat unfolds the milk proteins so they can wrap around each bubble and hold it there. No heat, no stable foam.
There’s a smaller reason too: warmth lifts the aromatics. A lot of what you think you’re tasting you’re actually smelling, and those compounds evaporate more readily when the drink is hot. Let a cappuccino go cold and it doesn’t just feel wrong, it genuinely smells of less.
It’s steamed to 55 to 65°C and served straight away, and going hotter is a mistake rather than a bonus: past about 70°C the milk starts to taste cooked.
Can a cappuccino be served cold?
Yes, but not by chilling a normal one, and this is where most advice goes wrong. You can’t pour hot steamed milk over ice and call it iced. Eater’s write-up on the technique explains why cafés resisted it for years: hot milk “raises the overall temperature of the beverage and may or may not increase the chances of growing bacteria in the drink. For this reason, many coffee bars will refuse to make customers an iced cappuccino.”
What changed is cold foam: milk aerated without heat or steam, usually skimmed because the higher protein and lower fat foams more readily. That’s the workaround the whole category rests on. As Eater puts it, cold foam is what makes the iced cappuccino possible in the first place.
That drink is its own thing rather than a footnote to this one, so it has its own page: what goes in it, how it differs from an iced latte, and what you will actually be handed if you order one is all in what is an iced cappuccino.
Which should you order?
If you want the drink the name refers to, order it hot and drink it fairly quickly. A cappuccino is small on purpose, and the foam starts breaking down from the moment it’s made, so it’s at its best early.
If it’s hot out, I’d order a freddo cappuccino over an iced one wherever you can find it, and an iced latte over a mediocre iced cappuccino everywhere else. A thin cold foam on top of an iced latte is an iced latte with extra steps.
