Dialling in is finding the grind setting that gives balanced flavour for today’s coffee and conditions. It doesn’t need to be complicated, and the right setup makes it faster.
Start with a recipe. A common starting point is 18g in, 36g out (a 1:2 ratio) in around 25–30 seconds. Your coffee may prefer something different, but you need a baseline to measure against.
Write that recipe down and keep it by the grinder. If you don’t know where you started, you can’t tell whether a change has helped.
Change one thing at a time
It is tempting to adjust dose, grind and time at once when a shot goes wrong. Resist that. Change one variable and the result tells you something; change three and you learn nothing. Grind is the best variable to adjust because it has the biggest, most predictable effect on flow rate.
The routine
- Weigh the dose and level the grounds with an Ikape distributor.
- Tamp with a calibrated tamper so pressure stays constant.
- Pull the shot on espresso scales with a timer.
- Taste it. Sour means grind finer, bitter means grind coarser.
- Change only the grind, then repeat.
- Once it tastes good, note the settings.
Fixing pressure and distribution means the grind is the only thing that changes between shots. That is what makes dialling in quick, rather than a guessing game.
For example, say your first shot runs 18g in and 36g out in 18 seconds and tastes sharp. That is fast and sour, so grind finer. If the next shot takes 34 seconds and tastes dry and bitter, you have gone too far, so come back a step. Two or three shots is usually enough.
Once the shot tastes good, log it. That record means the next barista starts from a proven setting rather than from scratch.
Re-check when
- You open a new bag of coffee
- The weather or humidity shifts noticeably
- Shots start running noticeably faster or slower
- You’ve been on the same setting for several hours
Useful kit
Keep tasting spoons and cups and a dial-in log next to the grinder. An Ikape espresso organiser keeps your tamper, distributor and brushes together, and some models include a knock box and tamping surface, so the whole workflow sits in one place and stays fast when the queue builds.
