a pattern.
Train your pouring motion. Find your rhythm. Turn a quiet moment into your signature spiral.
01 / Practice
Start at the center. Follow the guide outward with a light, steady motion.

YOUR INTENTION
Slow hands.
Deliberate circles.
Screen motion practice. No real water, extraction or taste measurement.
NO ACCOUNT · JUST A MOMENT OF FOCUSPOINTER / TOUCH / KEYBOARD01 — 06 / POUR STUDIES
A small ritual. A steadier hand.
Follow the water
Press and move inside the coffee bed. Lift your finger or release to pause the stream.
Read your pour
Review your path and time-weighted placement map. Choose one thing to repeat.
One bed. Different intentions.

YOUR POUR ANALYSIS
Your motion, made visible.
The map accumulates time at each pointer position, including pauses while holding. Brighter areas mean longer dwell, not stronger extraction.
—Center dwell
—Outer-zone dwell
—Pouring time
—Radial span
—Angular balance
—Pace variation
Finish a session to receive a motion observation.
How these metrics work
Center: inside 25% of the radius. Outer zone: beyond 80%. Radial span: maximum minus minimum radius. Angular balance: time-weighted entropy across eight sectors, excluding the inner 12%. Pace variation: speed standard deviation divided by mean speed; it can exceed 100%. A dash means insufficient motion data. These describe screen input, not extraction quality.
Your first Pourprint starts with one movement.

DAILY POUR CHALLENGE
One minute. One intention.
Today: follow a spiral, then try Free Pour. Compare your central dwell and outer-zone dwell, without chasing a taste score.
03 / FIELD NOTESTechnique begins with observation.
THE SCIENCE OF POURINGThe science behind the gesture.
Position is a choice
HARIO’s V60 guide describes pouring outward in a spiral while avoiding direct pouring on the paper filter. This is one brewing approach, not a universal scoring rule.
A rhythm you can repeat
Compare sessions under the same duration and mode. Central dwell and edge exposure describe where your cursor spent time; revolutions describe cumulative signed angular motion away from the center.
The screen has limits
A mouse or finger does not reproduce the weight of a kettle. Water flow, height, grind, temperature and taste are not measured. Test techniques with real coffee under consistent conditions.
04 / THE DETAILSGOOD QUESTIONS
FAQ
A little clarity before your next cup.
Why practise a spiral pour?
It makes spatial motion easier to observe and repeat. Use the guide to learn a pattern, then remove it in Free Pour.
Is center pouring wrong?
No. Center pouring is a distinct strategy. Compare where you spend time instead of treating more rotations as a better cup.
Does the heatmap measure extraction?
No. It shows time-weighted pointer placement on a virtual bed. It does not measure water volume, extraction uniformity or coffee taste.
How should I practise with a kettle?
Start with an empty kettle and comfortable movements, then practise safely with suitable equipment. This screen tool is for exploring motion and cannot certify real pouring skill.
