Brew Science
The reasoning behind your brew
yemen · Home Roast
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
Very soft bean — high extraction sensitivity
Low cell-wall resistance accelerates water flow through the bed — grind +14 from roast baseline. Temperature shifted downward to limit extraction rate. Reduces over-extraction risk.

The Intent
Body-forward extraction

Direct extraction
Active agitation
The Decisions
Grind · 69
Coarse grind — fast flow, controlled extraction
Looks like raw cane sugar crystals or cracked pepper. Derived from Stage 1 range 65–73. Natural offset: +6 (coarser), density +14. Limits over-extraction of process compounds.
Bloom · 40s
Short bloom — low CO₂, fast saturation
40s base — derived from bean density and process. Insufficient bloom causes channelling across all subsequent pours.
Temp · 92→88°C
Descending curve — 4°C drop across pours
Starts at 92°C — upper bound of Stage 1 range. Descends 2°C per pour as solubles concentration drops. Natural ceiling: 92°C. Hard constraint — range clipped at upper bound.
Pour Structure · 3 Pours
Three-pour structure — direct extraction
Light roast targets F1 range 4–5. Bean density (very-soft) favours fewer pours. Natural process: anchors structure at 4 pours.
Speed · 70 RPM
Higher RPM — body development
