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

Direct extraction

Active agitation

Grind · 42

Medium grind — balanced flow and contact

Looks like kosher salt or coarse table salt. Derived from Stage 1 range 38–46. Anaerobic offset: +8 (coarser). Limits over-extraction of process compounds.

Bloom · 45s

Short bloom — low CO₂, fast saturation

30s base — derived from bean density and process. Insufficient bloom causes channelling across all subsequent pours.

Temp · 90→85°C

Descending curve — 5°C drop across pours

Starts at 90°C — upper bound of Stage 1 range. Descends 2°C per pour as solubles concentration drops. Anaerobic ceiling: 91°C. Hard constraint — range clipped at upper bound.

Pour Structure · 4 Pours

Four-pour structure — balanced precision

Light roast targets F1 range 4–5. Bean density (medium) neutral. Anaerobic process: constrains range to 3–4 pours.

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.
