Brew Science
The reasoning behind your brew

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 · 44
Medium grind — balanced flow and contact
Looks like kosher salt or coarse table salt. Derived from Stage 1 range 38–46.
Bloom · 45s
Standard bloom — moderate CO₂ degassing
45s 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 · 5 Pours
Five-pour structure — maximum extraction control
Dark roast targets F1 range 3. Bean density (medium) neutral. Flat filter geometry: +1 pour for even bed coverage.
Speed · 87 RPM
Moderate RPM — aromatic protection
Pattern · Circular
Circular — critical flat-bed evenness
Flow Rate · 3 ml/s
Coupled to grind 44 — deterministic from grind range
