Grind Size
Very fine
Espresso is the foundation of cafe culture — a concentrated shot brewed under 9 bars of pressure. Mastering espresso requires precision in grind size, dose, tamp, and extraction time, but the reward is an intense, complex cup crowned with golden crema.
Equipment Needed
- Espresso machine (9-bar pressure)
- Burr grinder (espresso-capable)
- Tamper
- Scale with timer
- Portafilter and basket
- Shot glass or espresso cup
Step-by-Step Instructions
Warm up the machine
Turn on the espresso machine at least 15–20 minutes before brewing. Run a blank shot through the group head to stabilize temperature.
Dose and grind
Grind 18 g of coffee very fine — it should feel like powdered sugar. Dose directly into the portafilter basket.
Distribute and tamp
Use a distribution tool or finger to level the grounds evenly. Tamp firmly with 15 kg of pressure — the surface should be flat and polished.
Lock in and brew
Insert the portafilter into the group head and start the shot immediately. Aim for 36 g of liquid espresso in 25–30 seconds.
Evaluate the shot
A good shot starts dark, transitions to a golden-brown stream, and finishes with a thin, tiger-striped crema. It should taste balanced — sweet, slightly acidic, with a smooth finish.
Adjust if needed
If the shot runs too fast (sour, thin), grind finer. If too slow (bitter, ashy), grind coarser. Small adjustments make a big difference.
Pro Tips
- Freshness matters enormously for espresso — use beans 7–21 days from roast.
- Even tiny grind adjustments (a few microns) change the shot dramatically.
- Always purge the group head before locking in the portafilter.
- Weigh your output, not just your input — a 1:2 ratio (18 g in, 36 g out) is a good starting point.
