How to Prepare Your CoffeeItalian Espresso
Ratio breakdown
Ingredients run from the top of the cup to the bottom; the last item is the bottom layer. Values are normalized to a true 100% stack.
The whole of Italian coffee culture stands on this one 25-millilitre shot. Un caffè — the everyday order at the bar — is a single dose of seven grams pulled to twenty-five millilitres in about twenty-five seconds, the exact parameters the Istituto Nazionale Espresso Italiano certifies for 'Espresso Italiano.' It is not a strong coffee — it is a precise one, brewed at pressure into a crema that should hold for the length of a standing drink. The machine does the pressure; the barista does everything that makes the difference between a bitter splash and a balanced, syrupy shot. Order two shots pulled together — un doppio — and the dose simply doubles; it's this everyday single that the country's day is actually built around.

Steps
Heat the machine and warm the cup
A cold group and a cold cup steal heat from the shot exactly when the coffee is most fragile. Letting the machine reach full temperature and stacking the cup on the cup warmer means the brew runs at extraction temperature from the first drop.
Dose and distribute
Seven grams weighed into a single-dose basket, then distributed so the bed is level before any pressure is applied. A lopsided bed lets water find the path of least resistance, and under-extracted channels taste sour next to over-extracted edges.
Tamp level and firm
One level, firm tamp compresses the bed uniformly so the water meets even resistance across the whole puck. Crooked pressure tilts the extraction and leaves weak, blond patches in the crema.
Pull about 25 seconds to 25 ml
The certified ratio — seven grams in, twenty-five millilitres out, in about twenty-five seconds — is the balance point the Institute measured for sweetness against bitterness. The shot starts honey-thick and slowly thins; stopping at twenty-five millilitres keeps the dense body and syrupy mouthfeel the standard was built around.
Stop at blonding
The pale, foamy end of the shot — blonding — is where the puck runs out of solubles and starts releasing harsh, dry compounds. Cutting the shot as the stream lightens keeps that bitterness out of the cup.
Tips
- Ride the temperature — the machine's best espresso sits a degree or two under its hottest setting; if the shot runs bitter, let the group cool a few minutes and taste the difference.
- Warm the cup — a cold cup kills the crema and thins the body within seconds; the cup warmer on top of the machine exists for exactly this.
- Keep the puck tidy — knock the spent puck out and wipe the group basket between shots; stale grounds are the first thing that tastes when the next shot runs.
Common mistakes
- Tamping crooked — an uneven tamp tilts the whole extraction; one side of the puck chokes while the other runs blond before its time.
- Pulling too long — letting the shot run to 35 or 40 ml stretches the coffee past its balance point and drags the bitter tail of the puck into the cup.
- Grinding too fine or too coarse — a grind that stalls the machine at 40 seconds tastes ashy, while one that rushes through in 15 tastes sour and thin; the shot time is the feedback, not a suggestion.
FAQ
What's the difference between un caffè, un doppio, and ristretto/normale/lungo?
Un caffè is the everyday single — the certified seven grams in, twenty-five millilitres out. Order un doppio and the machine pulls two shots at once through a double basket, roughly fourteen grams in. Ristretto, normale, and lungo describe a different, newer methodology that modern specialty cafés worldwide — including many in Italy — use instead: sizing a shot by weight ratio off a larger dose, a dense 1:1.5 ristretto, a 1:2 normale, a thinner 1:3 lungo. It sits alongside the traditional single rather than replacing it.
Why 25 ml out of 7 g in?
The Istituto Nazionale Espresso Italiano's certification standard sets exactly this — seven grams (±0.5 g) of ground coffee, extracted at 9 bar and 88°C (±2°C) into twenty-five millilitres (±2.5 ml) in twenty-five seconds (±2.5 s). It's the balance point where the sweet, acid, and bitter fractions of the coffee all read in the cup; the machine's pressure and temperature are fixed, so dose and yield are what a barista actually controls to hit it.
