Precision hand grinding with all-metal construction and maximum portability.
The Timemore Chestnut C3S PRO is a significant evolution in manual coffee grinding. Upgraded with an all-aluminum body, full-metal internal structure, and a spring-loaded foldable handle, it delivers solid stability and exceptional durability without relying on plastic internal components.
At its core, the C3S PRO features 38mm SUS420 stainless steel S2C660 (Spike-to-Cut) conical burs. This patented geometric design cuts the coffee beans before grinding them, yielding high particle uniformity, reduced fines, and enhanced sweetness in the cup. From pour-over to espresso, the C3S PRO provides fast, smooth, and tactile grinding performance anywhere.

The grinder is the perfect size and weighs just 530g, making it easy to hold and carry, but it still has a decent capacity of 25 grams, enough to brew a cup or two in everyday use.

Frequently asked questions
What is the capacity of the C3S PRO?
The catch cup holds between 20g and 25g of coffee beans depending on the roast level, making it ideal for brewing 1 to 2 cups of specialty coffee.
Can the C3S PRO grind for both espresso and filter coffee?
Yes. The internal stepped click dial allows dial-in capability across brewing methods: 7–8 clicks for espresso, 13–16 clicks for pour-over, and 16–20 clicks for French Press or cold brew.
What makes the "PRO" model different from standard models?
The PRO version features a patented foldable crank handle that snaps flat against the body. This drastically reduces storage volume, making it easy to pack for travel or camping without removing the handle.
