Almost every café drink starts with espresso, a small, strong coffee made by forcing hot water through finely ground coffee. Add hot water for an americano, or steamed milk and foam for a latte or cappuccino.

Why it matters

Guests ask how drinks differ and notice when a cappuccino looks like a latte. Knowing the basics helps you get orders right.

Key ideas

01

Roast

Lighter roasts taste brighter and fruitier; darker roasts taste more bitter and chocolatey.

02

Single and double shots

A double uses twice the coffee of a single. Many cafés use it as the base for most drinks.

03

Milk and foam

A cappuccino has a thick foam layer, a latte is milkier with a thin one, and a flat white is smaller and stronger.

Step by step

  1. 1

    Note each drink's cup size on the menu.

  2. 2

    Learn the house recipe for shots, milk and foam.

  3. 3

    Taste a plain espresso to learn the house flavour.

  4. 4

    Practise describing each drink in one sentence.

  5. 5

    Ask a senior barista to check your drinks.

Do

  • Learn your café's own recipes, as names and sizes vary.
  • Offer decaf or plant-based milk when your café stocks them.
  • Ask one quick question when an order is unclear.

Common mistakes

  • Don't assume a drink name means the same everywhere.
  • Don't guess ingredients when a guest asks about allergies.
  • Don't correct how a guest pronounces a drink name.
On shift

The situation

A guest asks how a latte differs from a flat white. They want something strong but not too milky.

What a professional does

You explain that a flat white is smaller, with less milk, so the coffee tastes stronger. You recommend it and confirm their milk choice.

Useful phrases

“A flat white is smaller and stronger; a latte is bigger and milkier.”

“Would you like regular milk or one of our alternatives?”

Pro tip

Keep a recipe card by the machine until you know every drink.
