The reasoning behind your brew

The Analysis
Extraction Strategy
Body-focused extraction
Natural process and chocolate or nutty notes drive a body-first strategy. Higher agitation and spiral pours build texture and mouthfeel as the primary extraction target — clarity is secondary.
Bean Character
High-altitude bean — very dense cell structure
High cell-wall resistance limits water penetration — grind -6 from roast baseline. Bloom and temperature offset upward to compensate. Reduces uneven saturation risk across the bed.

The Intent
Body-forward extraction
Dense high-altitude beans
Layered extraction
Active agitation
The Decisions
Grind · 64
Coarse grind — fast flow, controlled extraction
Looks like raw cane sugar crystals or cracked pepper. Derived from Stage 1 range 60–68. Natural offset: +6 (coarser), density -6. Limits over-extraction of process compounds.
Bloom · 41s
Short bloom — low CO₂, fast saturation
41s base — derived from bean density and process. Insufficient bloom causes channelling across all subsequent pours.
Temp · 91→87°C
Descending curve — 4°C drop across pours
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 (very-dense) favours more pours. Natural process: anchors structure at 4 pours.
Speed · 70 RPM
Higher RPM — body development
Pattern · Spiral
Spiral — full bed agitation
Flow Rate · 3.2 ml/s
Coupled to grind 64 — deterministic from grind range
Target Time · 3:25
Predicted extraction ±15s — runs long? grind coarser
