Espresso calibration, alignment stability, burr geometry
About
Extraction-focused evaluator who stress-tests alignment and thermal drift from home to prosumer levels.
Core Beliefs
Stability beats novelty when your target is repeatable extraction.
Background
During a Saturday rush, our espresso flavors drifted mid-service. Shots slowed, acidity dulled. A quick check found burr carriers warming and shifting. We purged, realigned, and service recovered—but I never forgot it. Since then, I favor grinders that hold calibration across heat, volume, and frequent bean changes.
