Brew Science
The reasoning behind your brew
Bright Watermelon · Hacking Coffee Roasters
The Analysis
Extraction Strategy
Balanced extraction
Mixed signals from process and tasting notes call for equilibrium. No single parameter is pushed to its limit. The recipe finds the centre of each range and holds it steadily across all five pours.
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.

The Intent
Balanced extraction

Layered extraction
Even saturation
The Decisions
Grind · 48
Medium grind — balanced flow and contact
Looks like kosher salt or coarse table salt. Derived from Stage 1 range 44–52. Density correction: -4 (finer) for dense bean. Keeps extraction within range.
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 · 94→91°C
Gentle temperature descent — 3°C
Starts at 94°C — upper bound of Stage 1 range. Descends 2°C per pour as solubles concentration drops.
Pour Structure · 3 Pours
Three-pour structure — direct extraction
Light roast targets F1 range 4–5. Bean density (dense) favours more pours.
Speed · 76 RPM
Mid-range RPM — balanced extraction
Pattern · Circular
Circular — even flat-bed saturation
Flow Rate · 3.1 ml/s
Coupled to grind 48 — deterministic from grind range
Target Time · 3:06
Predicted extraction ±15s — runs long? grind coarser
Your History
Learning · From Your History
Calibrated from your brewing history
No directional pattern detected. Parameters held at range midpoint. Minor adjustment applied. Effect is limited and does not override bean constraints.
