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

Aromatic preservation

Dense high-altitude beans

Layered extraction

Even saturation

Grind · 41

Medium grind — balanced flow and contact

Looks like kosher salt or coarse table salt. Derived from Stage 1 range 38–44. LACTIC NATURAL PROCESS offset: +6 (coarser), density -4. Limits over-extraction of process compounds.

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 · 91→88°C

Gentle temperature descent — 3°C

Starts at 91°C — upper bound of Stage 1 range. Descends 1°C per pour as solubles concentration drops. LACTIC NATURAL PROCESS ceiling: 92°C. Hard constraint — range clipped at upper bound.

Pour Structure · 6 Pours

Six-pour structure — maximum extraction control

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