Pour Sequence · 5 Pours

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

Medium density — balanced extraction profile

Cell structure within standard extraction range. No density correction applied. Parameters follow roast and process constraints.

Engine Calibration

Aromatic preservation

Balanced density bean

Layered extraction

Even saturation

Grind · 47

Medium grind — balanced flow and contact

Looks like kosher salt or coarse table salt. Derived from Stage 1 range 43–51. Natural offset: +6 (coarser). Limits over-extraction of process compounds.

Bloom · 45s

Standard bloom — moderate CO₂ degassing

45s 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. Natural ceiling: 92°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 (medium) neutral. Natural process: anchors structure at 4 pours.
