Precision Grinder
Our flagship grinder: 83mm flat burrs with a stepless, high-resolution adjustment collar for the finest espresso micro-adjustments. Single-dose workflow with near-zero retention. Built for someone who wants to chase the last few percent of clarity and dial in precisely.
- Burr type: flat, 83mm
- Adjustment: stepless, high-resolution
- Workflow: single dose
- Retention: negligible
Flat burrs are less forgiving than conical — they reward good puck prep and a machine with stable temperature. We recommend it for the Duo, Flux, or Lever. It's overkill for the entry Pico or a single-boiler-only Solo setup, where the Compact or Vortex is a better-value match. See grinder burrs and the buying guide.
