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

High-altitude bean — very dense cell structure

High cell-wall resistance limits water penetration — grind -6 from roast baseline. Bloom and temperature offset upward to compensate. Reduces uneven saturation risk across the bed.

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.

Body-forward extraction

Dense high-altitude beans

Layered extraction

Active agitation

Grind · 53

Medium grind — balanced flow and contact

Looks like coarse sea salt. Derived from Stage 1 range 53–61. Natural offset: +6 (coarser), density -6. Limits over-extraction of process compounds. History pattern: -2. Minor — does not override bean constraints.

Bloom · 47s

Standard bloom — moderate CO₂ degassing

47s base — derived from bean density and process. Insufficient bloom causes channelling across all subsequent pours.

Temp · 88→88°C

Near-isothermal extraction

Starts at 88°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

Medium roast targets F1 range 4. Bean density (very-dense) favours more pours. 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.
