Material Purity
Ensure the grinder is made of stainless steel or aluminum with no plastic components touching the beans. This prevents chemical leaching and preserves flavor integrity.
Look for all-aluminum or all-steel claims in the description to confirm no hidden plastic parts.
Burr Type
Stainless steel conical burrs are durable and produce uniform grounds. They last longer than ceramic or blade alternatives.
Check that the burr material is listed explicitly as steel for best performance.
Capacity

A clear click system helps you reproduce your preferred settings easily.

Ease of Cleaning
