Extraction Strategy

Fermentation character control

Anaerobic fermentation produces complex winey compounds that over-extract faster than standard beans. Every parameter is constrained — RPM ceiling enforced, agitation controlled, temperature conservative — to manage fermentation character without losing it.

Bean Character

Very soft bean — high extraction sensitivity

Low cell-wall resistance accelerates water flow through the bed — grind +14 from roast baseline. Temperature shifted downward to limit extraction rate. Reduces over-extraction risk.

Engine Calibration

Fermentation control

Soft low-density bean

Layered extraction

Active agitation

Grind · 69

Coarse grind — fast flow, controlled extraction

Looks like raw cane sugar crystals or cracked pepper. Derived from Stage 1 range 66–72. Anaerobic offset: +8 (coarser), density +14. Limits over-extraction of process compounds.

Bloom · 50s

Standard bloom — moderate CO₂ degassing

47s base — derived from bean density and process. Insufficient bloom causes channelling across all subsequent pours.

Temp · 91→88°C

Gentle temperature descent — 3°C

Starts at 91°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 · 3 Pours

Three-pour structure — direct extraction

Light roast targets F1 range 4–5. Bean density (very-soft) favours fewer pours. 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.
