Espresso & Milk: The Basics
Flat white vs latte vs cappuccino — settled, finally, at your machine.
Same drink, three depths. Switch anytime — beginner steps assume no scale, barista steps assume no fear.
Every espresso-and-milk drink is the same two ingredients at different ratios and textures. Learn to pull one decent shot and steam one pitcher of milk, and the entire cafe menu unlocks: a cappuccino is not a different recipe from a latte — it is a different pour.
The method · Beginner
Know the map first
Flat white: double shot + ~130 ml milk, thin silky foam. Latte: double shot + 200 ml+, a finger of foam. Cappuccino: double shot + equal parts steamed milk and deep foam. Same shot, three destinies.
Pull the shot
18 g of finely ground coffee in the basket, tamp level and firm, and pull. You want roughly 36 g of liquid out in 25–30 seconds — a slow honey-drip that turns tiger-striped.
⏱ 0:28 timer in guided modeSteam: stretch then spin
Wand tip just under the milk surface for 3–4 seconds of paper-tearing hiss (that adds air), then bury it slightly to spin the milk in a whirlpool until the pitcher is too hot to hold for more than a moment.
⏱ 0:35 timer in guided modeGroom the milk
Tap the pitcher to pop big bubbles, swirl until it looks like wet paint. If it looks like bubble bath, spin longer next time.
Pour by drink
Latte: pour steadily from a height, foam last. Cappuccino: shake the foam in early. Flat white: swirl hard and pour thin, fast and low. Congratulations — you now understand the entire menu.

Dial in the shot
18 g in, 36 g out, 25–30 s (a 1:2 ratio). Sour and fast: grind finer. Bitter and slow: coarser. Change grind only, one step at a time.
⏱ 0:28 timer in guided modeMilk temps and texture
Steam to 55–65 °C. Flat white milk: 20–30 % foam expansion. Latte: ~25 %. Cappuccino: 50 %+. All air goes in during the first 5 seconds.
⏱ 0:35 timer in guided modeThe swirl is not optional
Swirl the pitcher continuously until the pour. Milk and foam separate in seconds; integration is texture.
Pour heights
Start high and thin to sink milk under the crema; finish low and fast to lay foam on top. That transition is 90 % of latte art.
One drink, daily
Make the same drink every day for two weeks, changing one variable. This is exactly how we will train our own bar staff.

Espresso spec
18 g → 36 g @ 25–30 s, 93 °C, 9 bar. Taste-first adjustments: acidity to sweetness via grind, body via dose, finish via temperature.
⏱ 0:28 timer in guided modeMilk chemistry
Proteins stabilise foam (steam 55–65 °C; above 70 °C they denature and the milk goes flat-sweet to cooked). Fat carries flavour — full cream for texture, low-fat for stiffer foam.
⏱ 0:35 timer in guided modeDrink architecture
Flat white 1:3 coffee:milk, microfoam <0.5 cm. Latte 1:4–1:5, foam ~1 cm. Cappuccino 1:1:1 thirds by tradition, modern 1:2 with 1.5 cm foam. Cortado 1:1, no foam ambition.
Workflow under service
Grind → dose → level → tamp → flush → lock → pull, steaming in parallel. Shot and milk should finish within 10 seconds of each other; espresso dies waiting.
Calibration ritual
First shot of the day is a sacrifice to the grinder gods. Taste it anyway; log it always.
↑ Level it up
Enthusiasts chase the 1:2 shot ratio and 55–65 °C milk. Baristas run shot and steam in parallel and can name the exact foam depth that separates a flat white from a latte — under half a centimetre.
Questions we always get
What actually is the difference between a flat white and a latte?
Ratio and foam. A flat white is smaller (≈1:3 coffee to milk) with barely-there microfoam; a latte is bigger (1:4+) with a visible foam layer. Same espresso underneath.
My milk screams when I steam. Is that right?
A brief paper-tearing hiss at the start is the sound of air going in — correct. A continuous scream means the wand tip is too deep or too shallow. Adjust by millimetres.
