How to Make Espresso at Home

Making espresso at home sounds intimidating, but the actual process is surprisingly simple once you understand what's happening. You're pushing hot water through finely ground coffee under pressure. That's it. The art is in dialing in the variables — grind size, dose, water temperature, and timing — until your shot tastes the way you want it to.

This guide walks you through pulling your first shot, then teaches you how to troubleshoot when something tastes off. No jargon without explanation, no gatekeeping.

What You Need

• —An espresso machine — any will do (see our recommendations)
• —A burr grinder — blade grinders can't produce a consistent espresso grind (see our recommendations)
• —Fresh whole bean coffee — roasted within the last 2–4 weeks
• —A scale — accuracy matters, even a cheap kitchen scale helps (our scale picks)
• —A tamper — your machine probably came with one, or (upgrade here)
• —A cup or shot glass

Step 1: Grind Your Coffee

Start with 18 grams of coffee ground fine — about the texture of table salt. If you're using a Breville machine, start around setting 5 and adjust from there. Every grinder is different, so treat any number as a starting point.

Grind size is the lever you'll pull most often. For a deep dive: Espresso Grind Size Explained.

Step 2: Distribute and Tamp

Pour the grounds into your portafilter. Give it a gentle shake or use a WDT tool to break up clumps and spread the grounds evenly. Then tamp with firm, level pressure — about 25–30 pounds. You're not trying to crush the coffee, just create a flat, even surface. If you have a calibrated tamper, just press until it stops.

Step 3: Pull Your Shot

Lock the portafilter into the group head and start your shot. You're aiming for roughly 36 grams of liquid espresso in about 25–30 seconds. Use a scale under your cup to measure the output.

What to watch for:

• —Runs too fast (under 20 seconds) → grind finer
• —Runs too slow (over 35 seconds) → grind coarser
• —Tastes sour → under-extracted — grind finer or extend the shot
• —Tastes bitter → over-extracted — grind coarser or shorten the shot

Step 4: Steam Your Milk (Optional)

If you're making a latte or cappuccino, steam your milk while the shot pulls. Submerge the steam wand tip just below the milk surface. You want to hear a gentle hissing — not screaming. Swirl to create a whirlpool. Stop when the pitcher is too hot to hold comfortably (around 150–160°F). Tap the pitcher on the counter to pop any large bubbles, then pour.

No steam wand? A NanoFoamer or milk pitcher can get you surprisingly close.

The Golden Ratio

Common Mistakes

• —Using pre-ground coffee — it goes stale fast and the grind is rarely right for your machine
• —Not weighing your dose — eyeballing is wildly inconsistent
• —Tamping too hard or too soft — a calibrated tamper removes this variable entirely
• —Neglecting to clean the machine — backflush weekly with Cafiza (see cleaning supplies)
• —Changing too many variables at once — adjust one thing at a time
