TIMEMORE Chestnut C3S Manual Coffee Grinder White

What the grinder is and who it serves

The TIMEMORE Chestnut C3S is a manual burr coffee grinder finished in white, built for home brewers who want a single device that handles espresso, pour-over, French press and V60. Its S2C conical burrs use harder SUS420 high-carbon stainless steel to keep particle size consistent across the range. The diamond-patterned body gives a secure grip during extended sessions, and the set ships with a storage bag and cleaning brush.

Behaviour during a long grinding session

Under sustained use the S2C burrs hold their alignment because the harder steel resists deformation, so the grind profile stays repeatable from the first dose to the last. The point-to-point adjustment lets you lock a setting and return to it without drift, while the ergonomic diamond texture reduces hand fatigue when you are working through 60 grams or more for a crowd. No motor means no heat buildup to alter flavour.

Installing and common pitfalls

There is no installation — you unpack, rinse the burrs with the included brush, and start grinding. The main issue users meet is forgetting to re-zero the adjustment after cleaning, which shifts the calibration by a few clicks. Another is under-dosing the hopper for espresso, causing the beans to dance and producing uneven fines. Keep the bag sealed between uses to stop the white finish picking up kitchen oils.
