TIMEMORE Chestnut C3S Manual Coffee Grinder — Black Aluminum, S2C Conical Burr, 36-Step Adjustable Grind

The TIMEMORE Chestnut C3S is a compact, all-metal manual coffee grinder featuring the S2C conical burr for consistent, low-fines grinding and 36-step adjustable coarseness—built for travel, home, and precise brewing.

Designed to bridge café-quality grinding with portability, the C3S upgrades the Chestnut line into a full aluminum-alloy body for improved durability and heat dissipation. Inside, the patented S2C660 hexagonal conical burr delivers even particle size and fewer ultrafine particles, while the bearing-assisted handle and folding design make long sessions and packing simple. Whether you brew espresso, pour-over, or French press, this grinder focuses on repeatable performance and easy maintenance.

How consistent is the grind across brewing methods?

The S2C660 conical burr and precision 5-axis CNC machining produce uniform grounds with a reduced amount of fines, making the C3S suitable for a wide range of recipes. You can dial in extraction more reliably than with basic blade or low-end burr grinders.

• Patented S2C hexagonal conical burr for even particle distribution
• 55–58 HRC hardness resists wear for stable performance
• 36-step adjustment enables fine-tuning from espresso to coarse press

Is it easy to use and comfortable for frequent grinding?

The handle uses a built-in bearing so it continues rotating smoothly after a push, reducing strain during longer sessions. The compact 52 mm body fits smaller hands and the upgraded folding handle stores neatly for travel.

• Ergonomic 52 mm body for secure grip and lightweight feel
• Low-effort milling thanks to precision burr geometry
• Folding handle locks for transport and saves space

How do I adjust grind size and maintain the grinder?

Adjustment is mechanical and intuitive: turn the nut clockwise for finer, anti-clockwise for coarser grounds across approximately 36 detents. Disassembly is straightforward—remove the top and brush out grounds; the aluminum exterior also tolerates travel wear well.

• 36-step coarse/fine adjustment for repeatable settings
• Simple brush cleaning—no special tools required
• Robust aluminum body resists dents and aids heat dissipation

Will this grinder hold up for travel and outdoor use?

The all-metal C3S was built with mobility in mind: a secure folding handle, light but sturdy aluminum shell, and a burr design that maintains performance despite rougher handling. It’s small enough for a backpack yet durable enough for frequent use.

• Full aluminum-alloy construction for ruggedness and lower weight
• Folding handle and compact size for packing into travel gear
• Easy to disassemble and clean while away from home

Who is this for: The TIMEMORE Chestnut C3S fits coffee lovers who want café-grade grind control without relying on electricity—travellers, campers, and home brewers seeking a compact grinder that balances precision, durability, and portability. If you value a long-lasting metal body, reliable conical burr performance, and granular control across brewing styles, the C3S is a practical, upgradeable choice.
