Timemore Chestnut S3 Manual Coffee Grinder
About the Brand
Timemore was founded in 2012 in China with a clear goal: bring café-level grinding precision into the hands of everyday coffee drinkers. By 2018 it had become the best-selling manual coffee grinder brand in China, and by 2020 its grinders, scales and brewing tools were reaching more than 42 countries worldwide. Backed by international design recognition and a philosophy built on professionalism, aesthetics, ease of use and honesty, Timemore has grown into one of the most recognised names in home coffee equipment.
The Product
The Timemore Chestnut S3 Manual Coffee Grinder is Timemore's flagship hand grinder — a full-metal unibody built around the patented S2C890 steel burr set and, for the first time in the Chestnut line, an external point-to-point precision adjustment ring. It's built for home brewers who want espresso-capable precision from a hand grinder, not just filter-grade consistency. This is Timemore's manual grinding technology taken as far as it currently goes.
Key Features
Patented S2C890 Steel Burrs (Uniform Grinding)
An upgrade from Timemore's S2C burr set, the S2C890 burrs are engineered for greater grind uniformity, ensuring beans are ground quickly and consistently. The result is cleaner, better-defined flavour from the same beans.
External Micro Adjustment Ring (Espresso-Grade Precision)
The S3 is Timemore's first hand grinder with an external point-to-point adjustment ring, capable of the high-precision settings espresso demands. One grinder now covers espresso, pour-over, French press and moka pot.
Multiple-Bearing Central Shaft (Fixed Grinding Core)
A fixed grinding core supported by multiple bearings keeps the burr set aligned under load, reducing wobble and improving grind consistency from the first crank to the last.
Customised High-Precision Bearings (20% More Precise)
Custom bearings increase grinding precision by 20% over the S3's predecessors, translating directly into tighter, more repeatable particle distribution.
Full Metal Unibody (Premium, Durable Build)
Constructed from aluminium and stainless steel with a silicone grip pad, the S3 is built to handle daily use without the wear points that plague plastic-bodied grinders.
Who It's Built For
The S3 is built for you if you want a single hand grinder capable of genuine espresso precision alongside filter and French press — without stepping up to an electric machine. It suits home baristas who've outgrown entry-level hand grinders and want Timemore's most refined manual technology.
One grinder, every method, no compromise on precision — that's the S3.
