Brew Science
The reasoning behind your brew
Karumandi Factory · Scenery
The Analysis
Extraction Strategy
Clarity-focused extraction
Washed process and clean tasting notes call for maximum transparency. Every parameter is tuned so the cup tastes exactly like the bean — nothing added, nothing lost.
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 · 41s
Short bloom — low CO₂, fast saturation
41s base — derived from bean density and process. Insufficient bloom causes channelling across all subsequent pours.
Temp · 90→90°C
Near-isothermal extraction
Starts at 90°C — upper bound of Stage 1 range. Descends 0°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 (medium) neutral.
Speed · 90 RPM
Moderate RPM — aromatic protection
Pattern · Circular
Circular — even flat-bed saturation
Flow Rate · 3 ml/s
Coupled to grind 42 — deterministic from grind range
Target Time · 3:00
Predicted extraction ±15s — runs long? grind coarser
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.
