Extraction Strategy

Balanced extraction

Mixed signals from process and tasting notes call for equilibrium. No single parameter is pushed to its limit. The recipe finds the centre of each range and holds it steadily across all five pours.

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

Brew Method · Drip on Ice

Concentrated brew — ice restores balance as it melts

Brewing 150ml of hot water directly onto 75g of ice. The pour targets 33% above equivalent hot-serve concentration — ice melts into the cup and dilutes the brew to its correct strength. Grind is tuned finer than a hot extraction at this ratio: ice melt reduces extraction efficiency, so the recipe pre-compensates with increased surface area.

Balanced extraction

Balanced density bean

Direct extraction

Active agitation

Grind · 61

Coarse grind — fast flow, controlled extraction

Looks like raw cane sugar crystals or cracked pepper. Derived from Stage 1 range 60–72. Natural offset: +6 (coarser). Limits over-extraction of process compounds. History pattern: -2. Minor — does not override bean constraints.

Bloom · 32s

Short bloom — low CO₂, fast saturation

32s base — derived from bean density and process. Insufficient bloom causes channelling across all subsequent pours.

Temp · 90→86°C

Descending curve — 4°C drop across pours

Starts at 90°C — upper bound of Stage 1 range. Descends 1°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

Medium roast targets F1 range 4. Bean density (medium) neutral. Natural process: anchors structure at 4 pours.

Learning · From Your History

Calibrated from your brewing history

Grind shifted finer by 2. Pattern was weak but consistent across recent brews. Minor adjustment applied. Effect is limited and does not override bean constraints.
