Kona Nightingale

Designed for: dark chocolate · roasted hazelnut

Home Roast · Hawaii, Kona

Washed · Dark

Pour Sequence · 3 Pours

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

Direct extraction

Active agitation

Grind · 71

Coarse grind — fast flow, controlled extraction

Looks like raw cane sugar crystals or cracked pepper. Derived from Stage 1 range 65–78. Density correction: +6 (coarser) for soft bean. Keeps extraction within range.

Bloom · 37s

Short bloom — low CO₂, fast saturation

37s base — derived from bean density and process. Insufficient bloom causes channelling across all subsequent pours.

Temp · 89→85°C

Descending curve — 4°C drop across pours

Starts at 89°C — upper bound of Stage 1 range. Descends 2°C per pour as solubles concentration drops.

Pour Structure · 3 Pours

Three-pour structure — direct extraction

Dark roast targets F1 range 3. Bean density (soft) favours fewer pours.
