How to Make Espresso at Home
Making espresso at home is simple in principle and rewarding to refine: fresh coffee, the right grind, an even tamp, and a well-timed shot. This guide walks through the steps and how to dial in a great espresso, whatever machine you own.
What You Need
To make espresso you need a machine that delivers proper pressure and temperature, fresh coffee beans, and a way to grind them finely and consistently, ideally a burr grinder. You will also want a tamper (often supplied), a scale if possible, and fresh, filtered water. Fresh coffee ground just before brewing is the single biggest factor in a good shot.
Grind and Dose
Espresso needs a fine, consistent grind, finer than for filter or cafetiere. Grind fresh and dose the right amount for your basket, commonly 14 to 18 grams for a double, levelling the grounds in the portafilter. Grind size is your main lever for adjusting the shot, so be ready to tweak it. A scale helps you keep the dose consistent from shot to shot.
Tamp
Tamp the grounds with firm, even pressure to create a level, compact puck, which makes the water flow through evenly. Consistency matters more than brute force: aim for the same level, even tamp each time. An uneven tamp lets water channel through the path of least resistance, giving a weak, uneven shot.
Pull the Shot
Lock the portafilter into the group head and start the brew. A standard double shot is roughly 36 grams of liquid espresso in about 25 to 30 seconds, though recipes vary. Watch the flow: it should start after a few seconds and pour like warm honey. Use your scale and a timer to judge it rather than guessing by eye.
Dial It In by Taste
Adjust to taste using grind as your main control. If the shot runs too fast and tastes sour or thin, grind finer. If it runs too slow and tastes bitter or harsh, grind coarser. Change one thing at a time. A few shots of practice gets you to a balanced espresso, and from there you can refine to your beans and preference.
Add Milk if You Like
For a flat white, latte or cappuccino, steam or froth milk and combine it with your shot. Straight espresso, an americano (espresso plus hot water), or milk drinks all start from the same well-pulled shot, so nail the espresso first and the rest follows.
Frequently Asked Questions
How do you make espresso at home?
Grind fresh coffee finely, dose the right amount into the portafilter, tamp it level and firm, then pull the shot, aiming for roughly a double of espresso in about 25 to 30 seconds. Adjust the grind to taste, and add steamed milk for milk-based drinks.
What grind do you need for espresso?
A fine, consistent grind, finer than for filter or cafetiere, produced by a good burr grinder. Grind is your main lever for adjusting the shot: finer slows it down and coarser speeds it up, so be ready to dial it in to taste.
Why does my espresso taste sour or bitter?
Sour, thin shots usually mean under-extraction, so grind finer or slow the shot down. Bitter, harsh shots usually mean over-extraction, so grind coarser. Change one variable at a time and use fresh coffee, since stale beans also cause off flavours.
