Extraction Strategy

Balanced extraction

Mixed signals from process and tasting notes call for equilibrium. No single parameter is pushed to its limit. The recipe finds the centre of each range and holds it steadily across all five pours.

Bean Character

Medium density — balanced extraction profile

Cell structure within standard extraction range. No density correction applied. Parameters follow roast and process constraints.

Engine Calibration

Balanced extraction

Balanced density bean

Layered extraction

Even saturation

Grind · 51

Medium grind — balanced flow and contact

Looks like coarse sea salt. Derived from Stage 1 range 48–58. History pattern: -2. Minor — does not override bean constraints.

Bloom · 41s

Short bloom — low CO₂, fast saturation

41s base — derived from bean density and process. Insufficient bloom causes channelling across all subsequent pours.

Temp · 92→88°C

Descending curve — 4°C drop across pours

Starts at 92°C — upper bound of Stage 1 range. Descends 1°C per pour as solubles concentration drops.

Pour Structure · 4 Pours

Four-pour structure — balanced precision

Medium roast targets F1 range 4. Bean density (medium) neutral.

Learning · From Your History

Calibrated from your brewing history

Grind shifted finer by 2. Pattern was weak but consistent across recent brews. Minor adjustment applied. Effect is limited and does not override bean constraints.
