TIMEMORE Chestnut C2S Manual Coffee Grinder — Black Full-Metal, 38mm CNC Burr, Adjustable Grind

The TIMEMORE Chestnut C2S is a precision manual coffee grinder with a full-metal body and a 38mm CNC stainless-steel conical burr designed for consistent, adjustable grinds whether at home or on the go.

Engineered as an upgrade to the original Chestnut C2, the C2S replaces fragile components with a robust full-metal shell and a durable CNC-machined burr assembly. It balances stability and portability—about 700 g of weight gives the grinder a premium feel while remaining easy to carry for travel or outdoor brewing. The C2S is aimed at brewters who want repeatable particle distribution across pour-over, French press, drip, and more, using a compact hand-crank design with an adjustable internal mechanism.

How precise is the grind adjustment for different brew methods?

The Chestnut C2S includes an internally adjustable grind setting that lets you fine-tune particle size from coarse to fine. The adjustment is secure and repeatable, reducing the need to re-calibrate between sessions. It works reliably across multiple brewing styles without generating excessive fines.

• 38 mm CNC stainless-steel conical burr for uniform particles
• Internal adjustment ring for precise, repeatable settings
• Low fines generation for cleaner cups
• Suitable for pour-over, French press, drip, and espresso-range tweaks

What makes the burr and grinding mechanism reliable?

The C2S burr is machined on 5-axis CNC equipment and heat-treated to a high hardness, which preserves edge life and maintains consistent cut quality. A double-bearing central axis stabilizes rotation, reducing wobble and uneven wear so particle distribution stays uniform over time. The design minimizes oversized shards and excessive powder.

• 55–58 HRC hardness rating on the milling blade
• Double-bearing center for stable rotation
• Precision-conical geometry for even extraction
• Reduced production of overly fine particles

How easy is it to use, clean, and carry?

The Chestnut C2S is built with user convenience in mind. Its ergonomically designed stainless-steel crank provides smooth, low-effort grinding so you can produce enough ground coffee for a large cup within about a minute. It disassembles for quick brushing and maintenance and its 700 g full-metal body feels substantial but remains portable.

• Lengthened stainless-steel handle for effortless operation
• Simple disassembly for brushing and cleaning
• 700 g body balances heft and portability
• Compact footprint fits travel kits or kitchen counters

Will this grinder hold up to regular use and transport?

The full-metal shell replaces brittle parts from earlier models, improving impact resistance and long-term durability. CNC-machined components and the hardened burr increase lifespan under frequent use. It's intended for daily home grinding as well as being robust enough to bring on trips or outdoor brews.

• Full-metal construction reduces breakage risk
• CNC-machined burrs resist wear and keep sharpness
• Secure internal fittings minimize loosening over time
• Portable form factor for travel-friendly brewing

Who is this for? The TIMEMORE Chestnut C2S suits coffee lovers who want a durable, travel-capable hand grinder with pro-level burr quality and precise grind control. It's ideal for people who switch brew methods, value consistent particle size, and want an ergonomic, low-effort grinder they can rely on at home, at work, or on the road.
