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

Medium density — balanced extraction profile

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

Engine Calibration

Fermentation control

Balanced density bean

Layered extraction

Active agitation

Grind · 49

Medium grind — balanced flow and contact

Looks like kosher salt or coarse table salt. Derived from Stage 1 range 44–54. Anaerobic offset: +8 (coarser). Limits over-extraction of process compounds.

Bloom · 50s

Standard bloom — moderate CO₂ degassing

46s base — derived from bean density and process. Insufficient bloom causes channelling across all subsequent pours.

Temp · 91→90°C

Near-isothermal extraction

Starts at 91°C — upper bound of Stage 1 range. Descends 0°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.
