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

Dense bean — elevated growing altitude

High cell-wall resistance limits water penetration — grind -4 from roast baseline. Bloom and temperature offset upward to compensate. Reduces uneven saturation risk across the bed.

Engine Calibration

Clarity-focused extraction

Dense high-altitude beans

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. Natural offset: +6 (coarser), density -4. Limits over-extraction of process compounds.

Bloom · 41s

Short bloom — low CO₂, fast saturation

41s base — derived from bean density and process. Insufficient bloom causes channelling across all subsequent pours.

Temp · 92→91°C

Near-isothermal extraction

Starts at 92°C — upper bound of Stage 1 range. Descends 0°C per pour as solubles concentration drops. Natural ceiling: 92°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 (dense) favours more pours. Natural process: anchors structure at 4 pours. Wave filter geometry: +1 pour for even bed coverage.
