Overview
An electric conical burr coffee grinder from Ollygrin with 40 millimeter stainless steel burrs, 30 grind settings from espresso to French press, and a 10-ounce bean hopper, in silver and black.
The grinder uses a gear-reduction motor that turns the burrs slowly rather than at high speed, which the company positions as a way to limit heat from friction during grinding. A friction clutch is built in to protect the gears if a small stone gets into the beans, and the motor has overheat protection on top of that.
- 40mm stainless steel conical burrs
- 30 adjustable grind settings
- 2-12 cup range
- Auto-locking bean hopper
Who it's for
For someone brewing anywhere from a single cup to a full pot who wants one grinder to cover espresso-fine through French-press-coarse grounds. Less useful for someone who only ever grinds one setting.
Pros and cons
- 30 grind settings from espresso to French press
- Gear-reduction motor to limit heat during grinding
- Friction clutch and overheat protection built in
- 10-ounce hopper with auto-locking design
- Single rotary dial control, no digital display or presets
- Larger hopper takes up more counter space
Performance notes
The 40mm conical stainless burrs and 30-position dial set the grind size, while the auto-locking hopper is meant to keep beans from spilling during removal or storage. The upper burr lifts off for cleaning, with a brush included for that purpose.
