Foam or froth — is there a difference?

The two words are used interchangeably in most of the coffee world, and no standards body distinguishes them. Anyone insisting on a hard difference is describing house usage rather than a definition.

The distinction that is real

Large-bubble foam — visible bubbles, stiff, sits on top of a drink, can be spooned, separates within a minute or two. What automatic jug frothers make, and what a traditional cappuccino wants.

Microfoam — bubbles too small to see, glossy, behaves like a liquid, pours and integrates. What a steam wand makes with a proper stretch-and-spin, and what latte art requires.

That difference changes the drink. Foam versus froth does not.

Loose conventions

Some usage does exist. Speakers often use froth for the airy, dry stuff and foam for anything aerated, but it is inconsistent and it varies by country.

The Italian schiuma covers both.

What to ask for

In a cafe, describing the drink is more reliable than describing the texture. A flat white implies microfoam; a cappuccino implies a foam layer. Asking for “extra froth” will get you whatever that barista thinks it means.

At home

Ignore the words and watch the surface. If it looks like wet paint, you have microfoam. If you can see individual bubbles, you have foam.
