Brew Science
The reasoning behind your brew
Rosasting House - Tiramisu · Roasting House
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 Decisions
Grind · 65
Coarse grind — fast flow, controlled extraction
Looks like raw cane sugar crystals or cracked pepper. Derived from Stage 1 range 60–72. Density correction: -6 (finer) for very-dense bean. Keeps extraction within range. History pattern: -1. Minor — does not override bean constraints.
Bloom · 40s
Short bloom — low CO₂, fast saturation
35s base — derived from bean density and process. Insufficient bloom causes channelling across all subsequent pours.
Temp · 89→85°C
Descending curve — 4°C drop across pours
Starts at 89°C — upper bound of Stage 1 range. Descends 1°C per pour as solubles concentration drops. Dark ceiling: 94°C. Hard constraint — range clipped at upper bound.
Pour Structure · 5 Pours
Five-pour structure — maximum extraction control
Dark roast targets F1 range 3. Bean density (very-dense) favours more pours. Flat filter geometry: +1 pour for even bed coverage.
Speed · 72 RPM
Higher RPM — body development
Pattern · Spiral
Spiral — aggressive bed saturation
Flow Rate · 3.2 ml/s
Coupled to grind 65 — deterministic from grind range
Target Time · 3:25
Predicted extraction ±15s — runs long? grind coarser
Your History
Learning · From Your History
Calibrated from your brewing history
Grind shifted finer by 1. Pattern was weak but consistent across recent brews. Minor adjustment applied. Effect is limited and does not override bean constraints.
