Dialing in is the process of adjusting grind until your shot hits its target yield in a reasonable time. Enter what you're aiming for and what actually happened, and this tool tells you which direction to adjust.
Diagnose Your Shot
Target yield
36.0 g
Typical time window
25–32s
On target
Yield and time both land in range — if the taste is right, keep this setting.
Time is a symptom, not the goal — always dial in by weighing the shot to your target yield first, then use time as a rough sanity check on the grind.
Machines That Make Dialing In Easier
Temperature stability and pre-infusion reduce shot-to-shot variation, so changes you make while dialing in actually show up consistently. These are our top-rated espresso machines.

The dialing-in process, step by step
Start with a known dose and target ratio (18g in, 36g out is a common 1:2 starting point), pull a shot, and weigh the actual yield while timing it. Compare both against your targets: if the yield is right but the time is far outside 25-32 seconds, or the time is right but the taste is off, grind size is almost always the first thing to adjust.
Change one setting, pull another shot, and re-taste. Resist the urge to change grind, dose, and tamping pressure all at once — you won't know which change actually mattered, and you'll have a harder time repeating a good result later.
Troubleshooting common dial-in issues
- Shot runs too fast. Grind finer, or check for channeling from uneven distribution or a poor tamp.
- Shot runs too slow, or stalls. Grind coarser — too-fine grounds can pack too densely for water to pass through evenly.
- Inconsistent results shot to shot. Check dose consistency first (weigh every dose), then look at distribution and tamping technique before blaming the grinder.
Frequently Asked Questions
Dialing in means adjusting grind size (and sometimes dose) until a shot hits your target yield within a reasonable time window and tastes balanced.
It's a process of small, one-variable-at-a-time adjustments, not a single setting you find once and never touch again — grind needs re-dialing as beans age or change.
