Extraction Strategy

Body-focused extraction

Natural process and chocolate or nutty notes drive a body-first strategy. Higher agitation and spiral pours build texture and mouthfeel as the primary extraction target — clarity is secondary.

Bean Character

Soft bean — low-resistance extraction

Low cell-wall resistance accelerates water flow through the bed — grind +6 from roast baseline. Temperature shifted downward to limit extraction rate. Reduces over-extraction risk.

Engine Calibration

Body-forward extraction

Soft low-density bean

Layered extraction

Active agitation

Grind · 65

Coarse grind — fast flow, controlled extraction

Looks like raw cane sugar crystals or cracked pepper. Derived from Stage 1 range 61–69. Extended Fermentation Natural offset: +6 (coarser), density +6. Limits over-extraction of process compounds.

Bloom · 46s

Standard bloom — moderate CO₂ degassing

46s 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 2°C per pour as solubles concentration drops. Extended Fermentation Natural ceiling: 92°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 (soft) favours fewer pours. Extended Fermentation Natural process: anchors structure at 4 pours.
