Timemore Chestnut C3S Pro – Manual Coffee Grinder

Timemore Chestnut C3S Pro: precision, robustness, and quality in every grind

The Timemore Chestnut C3S Pro is designed for those who want to get the most out of their coffee, thanks to uniform and consistent grinding. The new design with all-metal body and folding crank combines elegance, robustness, and practicality, making it the ideal companion for both daily use and travel.

38 mm CNC steel conical burrs

The conical burrs in stainless steel are machined with 5-axis CNC and boast a hardness of 55–58 HRC, ensuring high wear resistance and extremely uniform grinding. The system minimizes the production of unwanted fine particles ("fines"), improving extraction and cup clarity.

Precise grind adjustment

The manual adjustment system offers about 36 grind levels, allowing easy adjustment of grind size to any extraction method.

Ideal for:

• Espresso.
• Moka.
• Filter coffee (V60, Origami, Kalita).
• AeroPress.
• Chemex.
• French Press.
• Cold Brew.

Turning the selector:

• Clockwise results in a finer grind.
• Counterclockwise results in a coarser grind.

Smooth and effortless grinding

The system with double bearing keeps the grinding shaft perfectly centered, increasing stability and precision during use. The rotation is particularly smooth and requires little force, while the compact body of 52 mm diameter ensures a comfortable grip even for smaller hands.

Designed to accompany you everywhere

The new folding crank makes the C3S Pro even more practical to carry, taking up less space in your backpack or suitcase without sacrificing the typical sturdiness of Timemore products. It’s the ideal solution for home, office, camping, or travel.

Easy to clean

The grinder can be quickly disassembled for routine maintenance. Simply use a brush to remove coffee residues, no need to wash with water.
