Precision Grinding for Coffee Enthusiasts

The TIMEMORE Chestnut S3 is a manual burr grinder designed for users who demand exact particle control across brewing methods. Its 30g capacity suits single-serve preparation at home, in the office or while travelling. The 0.015mm per grid adjustment provides point-to-point precision for dialling in espresso or filter recipes without counting clicks. A foldable handle and full metal unibody construction make it a durable, portable companion for daily rituals.

Consistent Operation with Minimal Effort

The S2C890 grinding core delivers high uniformity for balanced flavour extraction and enhanced acidity. Customised high-precision bearings increase accuracy by 20%, reducing tolerance to 5 microns and doubling dimensional stability during grinding. The all-metal unibody resists flex, keeping burr alignment steady throughout the dose. Manual operation produces no electrical noise or heat, preserving volatile aromatics in every cup.

Patented Portability and Ready-to-Use Design

The unique spring-assisted foldable handle collapses flush against the body, reducing packed volume for travel or camping kits. No additional tools are required for grind adjustment; the external dial moves in precise 0.015mm steps directly on the grinder. The 30g hopper and grounds catch are integrated into the unibody, eliminating loose parts. The black CNC stainless steel finish resists wear and cleans easily between brews.

Questions about this item

How do I assemble the foldable spring-assisted handle so it locks in place?

Extend the handle until the spring clicks into the detent; the patented mechanism holds it rigid during grinding and folds flat for storage without tools.

What part will wear first and need replacement on the S2C890 burr set?

The 890 steel burrs themselves are the primary wear item; high-precision bearings are rated for extended life and are not user-serviceable.

At what grind setting does the 0.015 mm per step adjustment reach its practical limit for espresso?

The ultra-fine steps continue until the burrs nearly touch; the limit is the point where resistance spikes and fines clog the S2C890 core, typically just past the finest usable espresso notch.
