KEY TAKEAWAYS
- Use an identical kettle flow and pour height before blaming the burr gap for V60 timing.
- A late drawdown matters most when it arrives with muddled flavor or visible fines migration.
- Accept the setting when a repeated cup preserves sweetness without demanding corrective pouring.

Hand-grinder click counts do not transfer reliably between models—or always between two units of the same model. Record your grinder and zero point before using this relative test.
- Three-setting comparison
- Current V60 mark, one click open, one click closed
- Controlled constants
- 15 g coffee / 250 g water / 94°C / three equal pours
- Primary signal
- Pulse recovery, final drawdown and bed shape
- Stop rule
- Two brews finish in the same range with an even, sweet cup
Five-run sequence
- Write down the grinder model, burr condition and the zero point you can return to.
- Set the stated baseline and keep coffee, water, dose, temperature and technique fixed.
- Brew the reference cup once without correcting it midway.
- Move only to the neighboring coarser or finer setting named in this note.
- Complete at least three comparable runs, then keep the setting only if the full result range supports it.
Record for every run
- Coffee, roast date and roast level
- Water source, dose and temperature
- Grinder model, zero point and setting
- Total time and the page-specific measurement
- Taste result, correction and reason to stop

Separate grind from pouring
Select the hand grinder setting that previously produced a reasonable V60 and place one click on either side of it. The trial recipe is 15 g coffee to 250 g water at 94°C: a 45 g bloom for forty seconds, then three calm pours ending near 2:00. Mark pour heights on a practice vessel if your kettle technique varies.
Rinse the same filter type and keep the dripper, server and water unchanged. Record the water level immediately before each pulse. That recovery level reveals whether the bed is draining consistently even when the final clock time looks acceptable.
Map open, centre and closed
Brew at the centre mark, open the grinder by one click for the second sample, then close it by one click from centre for the third. Return the adjustment ring to zero only when the grinder's instructions permit it; repeated hard contact can damage the burr edges.
Use the same circular path and avoid rescuing a slow cup with a higher pour. Note bloom drainage, the time each pulse exposes part of the bed and the final drip. A target around 2:45 to 3:30 is a comparison window for this recipe, not a pass mark for every coffee.
Interpret the V60 bed
The coarse sample may finish quickly yet taste bright and empty; the finer sample may become sweeter before it begins to dry. Look for a bed without a deep central crater and for walls that are not coated with an unusual band of fines. Bed appearance supports the cup result but cannot overrule it.
When two settings taste close, prefer the one whose pulse recovery remains stable. A cup that needs a special final pour to finish on time is fragile. The goal is a burr gap that tolerates normal technique, not a theatrical bed photograph.
Respond to a flow error
If the coffee is sharp and the bed drains before each planned pulse, close one click. If drawdown stretches while the cup turns rough, open one click and reduce swirling on the confirmation brew. If the clock is late but the coffee is clear and sweet, keep the setting and record the coffee's flow character.
Stop when the same setting repeats within a fifteen-second drawdown band and the cooled cups agree on balance. Do not continue finer merely to reach a generic time; the next step may add dryness without adding useful extraction.
Keep a V60 flow record
Log grinder and click, filter lot, coffee age, water temperature, bloom mass, end time for each pour, final drawdown, bed note and flavor at hot and warm temperatures. A simple row per brew makes a change in pouring visible instead of hiding it inside a taste adjective.
Save the centre and winning settings together. On the next bag, begin at the winner but rerun the centre if drawdown moves by more than thirty seconds. That protects the map from becoming a permanent rule for coffees with different density or roast development.

PRACTICAL QUESTIONS
Is a flat V60 bed proof that the grind is correct?
No. It is one observation. Use drawdown consistency and the cooled cup as the deciding evidence, because pouring can produce a tidy bed with an unbalanced extraction.
What if the best V60 cup falls outside the time window?
Keep the better cup and document its time. The window is useful for comparing this fixed recipe, not for rejecting a coffee that flows differently.
