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

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

Clarity-focused extraction

Soft low-density bean

Layered extraction

Even saturation

Grind · 44

Medium grind — balanced flow and contact

Looks like kosher salt or coarse table salt. Derived from Stage 1 range 38–46. Density correction: +6 (coarser) for soft bean. Keeps extraction within range.

Bloom · 40s

Short bloom — low CO₂, fast saturation

35s base — derived from bean density and process. Insufficient bloom causes channelling across all subsequent pours.

Temp · 94→91°C

Gentle temperature descent — 3°C

Starts at 94°C — upper bound of Stage 1 range. Descends 1°C per pour as solubles concentration drops.

Pour Structure · 5 Pours

Five-pour structure — maximum extraction control

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