Using an espresso machine means grinding fine, dosing 18–20 grams, tamping evenly, and brewing for 25–30 seconds.
The first time you face a portafilter, the process can feel fussy. But the routine is short, repeatable, and worth mastering — especially if you’ve got a machine gathering dust. The payoff is a crema-topped shot that beats anything from a pod, at a fraction of cafe prices. Here’s the full workflow, from cold machine to rinsed portafilter.
Set Up the Machine and Get It Hot
Start by filling the water reservoir with fresh tap water (unless plumbed directly into your home’s supply). KitchenAid’s guidance is simple: fill the tank, switch the machine on, and give it time to heat up. TechRadar warns against overfilling, which can cause leaks — so fill to the marked line, not the brim.
Once the machine signals it’s ready, run a blank shot — water with no coffee — through the group head. This heats the metal parts that touch your coffee. Run a little water through the portafilter basket itself, and warm your cup on the drip tray or by rinsing it with hot water. A cold portafilter steals heat from your shot, and a cold cup dulls the crema.
Grind, Dose, and Tamp Like the Recipe Says
Espresso needs a fine grind, closer to powdered sugar than table salt. KitchenAid specifies a fine espresso grind, and TechRadar notes finer grounds extract more flavor and produce a stronger cup. Pre-ground drip coffee is too coarse — have it ground for espresso instead.
Use the double basket — many machines include single and double baskets, so check which is loaded. KitchenAid adds that some models require a non-pressurized filter basket for a double cup; a pressurized basket uses a built-in baffle to fake crema, while a non-pressurized one lets the true shot develop.
Distribute the grounds evenly, then tamp with firm, level pressure. The key is consistency: the same pressure every time gives a repeatable shot. If unsure, press until the coffee feels solid and won’t shift when you tilt the portafilter.
Brew the Shot and Steam the Milk
Lock the portafilter into the group head and start the brew. If it runs faster, your grind is too coarse; if it drips slowly, it’s too fine. Adjust the grind, not the dose, to fix the timing.
For milk drinks, steam after the shot. Purge the steam wand briefly into the sink to clear condensed water, then submerge the tip just below the surface of cold milk. Keep the tip near the surface to stretch the milk, then sink it deeper to swirl and heat until glossy, not foamy.
Clean Up Before the Milk Dries
The cleanup is short but non-negotiable. Purge the steam wand again, then wipe it down immediately — milk residue hardens fast and breeds bacteria. KitchenAid and TechRadar both stress cleaning the wand right after steaming.
Knock the spent puck into the bin, rinse the portafilter and basket under hot water, and run a blank shot through the group head to flush lingering oils (which also backflushes debris off the shower screen on three-way valve machines). Then wipe the drip tray. Done.
A few mistakes sink most beginners. Not preheating fully produces sour, under-extracted shots. Skipping the wand purge leaves stale milk taste. And forgetting that pod machines work completely differently will confuse you — they skip grinding, dosing, and tamping entirely. If you’d rather have one machine for both espresso and drip coffee, our tested roundup of best combination coffee and espresso machines shows the models worth your money.
| Step | Target | Common Mistake |
|---|---|---|
| Dose | 18–20 g for a double | Using the single basket by accident |
| Grind | Fine, like powdered sugar | Using pre-ground drip coffee |
| Extraction | 25–30 seconds | Adjusting dose instead of grind to fix timing |
| Milk temp | 140–150°F | Letting the wand sit dirty after steaming |
FAQs
Why is my espresso shot coming out too fast?
A shot under 25 seconds is usually ground too coarse; water rushes through large gaps, extracting only sour, acidic compounds. Grind finer — one or two notches — then watch the timing. Change one variable at a time so you know which fix worked.
Do I need a special grinder for espresso?
Yes. Blade grinders chop unevenly, producing dust and chunks that extract badly. Burr grinders crush beans uniformly, enabling even extraction. Look for a grinder with fine adjustment steps, since one notch makes a visible difference in brew time.
How often should I descale my espresso machine?
Scale blocks water flow, raising pressure and slowing shots. Use the maker’s descaling solution and follow the manual’s exact cycle — skipping the rinse leaves acidic residue.
