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 · 39

Fine grind — high extraction contact

Looks like standard table salt or fine sea salt. Derived from Stage 1 range 36–42. Washed Double Anaerobic Thermal Shock offset: +8 (coarser), density -4. Limits over-extraction of process compounds.

Bloom · 50s

Short bloom — low CO₂, fast saturation

39s base — derived from bean density and process. Roast date adjustment: extended 11s for elevated CO₂. Insufficient bloom causes channelling across all subsequent pours.

Temp · 91→91°C

Near-isothermal extraction

Starts at 91°C — upper bound of Stage 1 range. Descends 0°C per pour as solubles concentration drops. Washed Double Anaerobic Thermal Shock ceiling: 91°C. Hard constraint — range clipped at upper bound.

Pour Structure · 5 Pours

Five-pour structure — maximum extraction control

Light roast targets F1 range 4–5. Bean density (dense) favours more pours. Washed Double Anaerobic Thermal Shock process: constrains range to 3–4 pours. Wave filter geometry: +1 pour for even bed coverage.
