Extraction Strategy

Clarity-focused extraction

Washed process and clean tasting notes call for maximum transparency. Every parameter is tuned so the cup tastes exactly like the bean — nothing added, nothing lost.

Bean Character

Dense bean — elevated growing altitude

High cell-wall resistance limits water penetration — grind -4 from roast baseline. Bloom and temperature offset upward to compensate. Reduces uneven saturation risk across the bed.

Engine Calibration

Clarity-focused extraction

Dense high-altitude beans

Direct extraction

Even saturation

Grind · 42

Medium grind — balanced flow and contact

Looks like kosher salt or coarse table salt. Derived from Stage 1 range 38–46. Density correction: -4 (finer) for dense bean. Keeps extraction within range.

Bloom · 31s

Short bloom — low CO₂, fast saturation

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

Temp · 96→93°C

Gentle temperature descent — 3°C

Starts at 96°C — upper bound of Stage 1 range. Descends 1°C per pour as solubles concentration drops.

Pour Structure · 6 Pours

Six-pour structure — maximum extraction control

Light roast targets F1 range 4–5. Bean density (dense) favours more pours. Wave filter geometry: +1 pour for even bed coverage.

Calibrated from your brewing history

No directional pattern detected. Parameters held at range midpoint. Minor adjustment applied. Effect is limited and does not override bean constraints.
