- In the cup
- 36g
- Time
- 25–30 sec
- Grind
- Fine
Method
- Switch the machine on early and lock the empty portafilter in to heat.A cold handle or group pulls heat from the shot and makes it sour.
- Dry the basket, grind the coffee in, and tap or level it so the bed is even.Water finds the easiest path; gaps or a lopsided bed mean uneven, thin espresso.
- Tamp firmly and straight. Run a second of water through the group, lock in and start straight away.Flushing clears old coffee; waiting lets the hot group start cooking the grounds.
- Stop at about 36g in the cup, roughly double the dry coffee, in 25–30 seconds.
If it's not right
- Fast, sour, thin: grind finer.
- Slow, bitter, harsh: grind coarser.
- Spurts or pale patches: level and tamp more evenly.
Bean-to-cup: start on one of the finer grind settings with strength set to high. Many machines only let you change the grind while the grinder is running, so check your manual.
