The reasoning behind your brew
The Jewel · Captain + Stoker Coffee Roasters
The Analysis
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.

The Decisions
Grind · 42
Medium grind — balanced flow and contact
Looks like kosher salt or coarse table salt. Derived from Stage 1 range 38–46.
Bloom · 40s
Short bloom — low CO₂, fast saturation
40s 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 (medium) neutral.
Speed · 112 RPM
Moderate RPM — aromatic protection
Pattern · Circular
Circular — controlled cone extraction
Flow Rate · 3 ml/s
Coupled to grind 42 — deterministic from grind range
Target Time · 2:59
Predicted extraction ±15s — runs long? grind coarser
