Brew Science
The reasoning behind your brew
Duber Mejia · SEY
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 Intent

Layered extraction
Even saturation
The Decisions
Grind · 40
Fine grind — high extraction contact
Looks like standard table salt or fine sea salt. Derived from Stage 1 range 36–44.
Bloom · 35s
Short bloom — low CO₂, fast saturation
35s base — derived from bean density and process. Insufficient bloom causes channelling across all subsequent pours.
Temp · 93→93°C
Near-isothermal extraction
Starts at 93°C — upper bound of Stage 1 range. Descends 0°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. Flat filter geometry: +1 pour for even bed coverage.
Speed · 82 RPM
Moderate RPM — aromatic protection
Pattern · Circular
Circular — critical flat-bed evenness
Flow Rate · 3 ml/s
Coupled to grind 40 — deterministic from grind range
Target Time · 2:51
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.
