Cup quality across 17 attempts
Each point is a roast scored from tasting notes (1 = miss, 5 = dialed in). The series stops at the teal halo — once dialed in, later repeats aren’t scored the same way.
Where the good cups live
Roast level vs batch size. Color = profile family; larger dots = better cups. Notice how quality clusters once batch size moves to 100–120g.
Roast mechanics that stuck
DTR, roast loss, and rate-of-rise across attempts with klog data. Each series is scaled on its own axis so shapes are comparable.
What the data taught us
- 1Batch size was the hidden variable — 60g loads underperformed 100–120g on the same profiles.
- 2F-WSH 1500-2200 at level 2.0 / 120g became the repeatable winner (sweet + fruity, closest to Rocket Coffee Gatugi).
- 3Name-matched Rocket Gatugi at 60g ran to ~30% DTR and muted fruit — profile name ≠ automatic win.
- 4Once dialed in, later batches are confirmations — no need to re-score every cup.
