Coffee Grinder Burr & Spec Data
Burr type and size, espresso capability, adjustment, retention and street price for every grinder we researched — sortable.
The hard specs behind our coffee and espresso grinder picks. Every grinder's burr geometry (flat vs conical, diameter in mm), drive (electric vs hand), adjustment mechanism, espresso capability, retention behavior, and estimated street price. Sort any column. Prices are roundup-sourced street estimates, not live quotes.
| Electric or hand-cranked | Flat vs conical — geometry shapes particle distribution | Bigger burrs generally grind faster and more evenly | Stepless vs stepped — finer steps ease espresso dialing | Grinds fine enough to dial in espresso shots | Retention Grounds left behind between doses, per reviews | Roundup-sourced estimate — unverified, not a live quote | ||
