Extraction Strategy

Aromatic preservation

Fruity, floral, or tropical notes contain volatile aromatic compounds that evaporate under excess heat or agitation. Lower RPM, controlled temperature descent, and circular pours were chosen specifically to protect these characteristics through the full extraction.

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

Brew Method · Drip on Ice

Concentrated brew — ice restores balance as it melts

Brewing 165ml of hot water directly onto 60g of ice. The pour targets 27% 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.

Aromatic preservation

Dense high-altitude beans

Layered extraction

Even saturation

Grind · 38

Fine grind — high extraction contact

Looks like standard table salt or fine sea salt. Derived from Stage 1 range 38–46. Density correction: -4 (finer) for dense bean. Keeps extraction within range. History pattern: -2. Minor — does not override bean constraints.

Bloom · 44s

Short bloom — low CO₂, fast saturation

44s base — derived from bean density and process. Insufficient bloom causes channelling across all subsequent pours.

Temp · 96→93°C

Gentle temperature descent — 3°C

Starts at 96°C — upper bound of Stage 1 range. Descends 1°C per pour as solubles concentration drops.

Pour Structure · 4 Pours

Four-pour structure — balanced precision

Light roast targets F1 range 4–5. Bean density (dense) favours more pours. Wave filter geometry: +1 pour for even bed coverage.

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.
