Timemore Chestnut C5 ESP PRO: Manual Coffee Grinder, 42mm Conical Burrs, Micron-Level Adjustment

Manual control taken to the extreme

The Timemore Chestnut C5 ESP PRO is a manual coffee grinder built for espresso, where every micron of adjustment matters. Its 42mm stainless steel conical burrs deliver uniform grounds, shot after shot.

What sets it apart

The internal adjustment dial offers 50 clicks per rotation, each one moving the burr by just 0.015mm. This precision allows grind size to be dialed in to the micron, for espresso as well as coarser methods. Dual-axis bearings, with a 7-micron tolerance, keep the central shaft stable during grinding.

Day to day

The XL funnel makes dosing beans easy without spills, and the crank turns smoothly with one hand thanks to the stability of the central shaft. A cleaning brush is included to clear coffee residue after each grind.

Who it's for
