How to Prepare Your CoffeeItalian Espresso
The whole of Italian coffee culture stands on this one 36-gram shot. In Italy an espresso is not a strong coffee — it is a precise one, brewed at pressure for twenty-five or thirty seconds into a crema that should hold for the length of a standing drink at the bar. The machine does the pressure; the barista does everything that makes the difference between a bitter splash and a balanced, syrupy shot. This is the recipe the country's day is 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
Eighteen grams weighed into the 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 25–30 seconds to 36 g
Two-to-one extraction in half a minute balances sweetness against bitterness. The shot starts honey-thick and slowly thins; stopping at 36 g keeps the dense body and syrupy mouthfeel the ratio was designed 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 45 or 50 grams 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 ristretto, normale, and lungo?
The three are the same dose run to different ends. A ristretto stops around 1:1.5 — less water, denser and sweeter, the way an Italian afternoon shot is often drunk. A normale is the standard 1:2 recipe here. A lungo pushes toward 1:3, and the extra water thins the body and pulls more bitterness out of the tail.
Why 36 g out of 18 g in?
Two-to-one is the balance point where the sweet, acid, and bitter fractions of the coffee all read in the cup. Under it the shot tastes thin and sour; over it the bitter tail takes over. The machine's pressure and temperature are fixed, so yield is the one variable the barista controls to hit that balance.
