The Timemore Chestnut S3 is Timemore's flagship hand grinder — genuinely capable across the full range from moka pot and espresso through to French press, built around a larger 42mm burr set for faster, more consistent grinding than the smaller grinders in the range.
The 42mm SUS420 stainless steel burr set uses Timemore's S2C660 'Spike-to-Cut' geometry, running on dual bearings with just 5 micrometres of clearance between shaft and bearings for minimal wobble. The camera-lens-style external dial gives 90 stepped clicks at 15 micrometres per click, so you can move cleanly between an espresso grind and a French press grind on the same grinder.
A patented foldable, spring-assisted handle and anti-slip silicone base make it as easy to use on a kitchen counter as it is to pack for travel.
The Chestnut S3 is built for coffee lovers who want one grinder to genuinely cover everything — from a fine espresso grind through to a coarse French press grind — without owning two grinders or fighting a burr set that's only really tuned for one end of the range. It suits anyone serious enough about their coffee to want dual-bearing stability and repeatable, click-based precision, whether that's at home or on the road.
