Understanding the Three Variables
Every espresso problem is caused by one of three things: dose (how much coffee), yield (how much liquid), or time (how long extraction took). Before pulling a shot, decide your target: we recommend 20 g in → 40 g out → 25–30 seconds.
Dialling In Your Grind
Pull a shot with your starting dose. If it runs in < 20 seconds, grind finer. If it runs > 35 seconds, grind coarser. Make one grind adjustment at a time and re-pull.
Distribution & Tamping
Use a distribution tool (or the Stockfleth move) to level the grounds before tamping. Tamp with firm, even pressure — around 15 kg. An uneven puck causes channelling, where water finds the path of least resistance and under-extracts most of the coffee.
The Shot
Place your cup (pre-warmed) on a scale, tare to zero, lock in the portafilter, and start your timer as you hit the brew button. Watch the first drops appear — they should be dark syrup, not a light stream.
Tasting & Adjusting
Taste the shot immediately at around 40 °C. Sour? Under-extracted — grind finer or increase dose. Bitter? Over-extracted — grind coarser or decrease dose. Perfect shots have sweetness, acidity, and bitterness in balance.
