Frequently Asked Questions

What's the difference between the C3S Pro and the C3S Pro Max?
The Pro Max features larger 35g capacity and slightly bigger burrs. The C3S Pro has 25g capacity and is more compact—perfect if portability is your priority. Both have the same S2C burr design and build quality.

Can I grind fine enough for espresso?
Yes. The C3S Pro handles espresso grinding exceptionally well, with 36 adjustment levels allowing precise dialling in for various roast levels and machines.

How do I clean the burrs?
Disassemble the grinder by removing the adjustment nut and handle. Remove the outer burr, brush away coffee residue with the included brush. For deep cleaning every few months use products from our Cafetto collection.

Is the foldable handle durable?
Absolutely. Timemore's patented folding mechanism is engineered for thousands of fold cycles. The all-metal construction ensures the handle remains secure during grinding and folds smoothly for storage.

How long does it take to grind 20g of beans?
At approximately 1g per second, you can grind 20g in around 20-25 seconds with consistent cranking speed.

Does it work well for light roast coffees?
Yes. The S2C burr design with its spike-to-cut geometry handles dense light roasts efficiently, requiring less effort than traditional conical burrs whilst maintaining excellent particle consistency.

Can I adjust grind size with beans in the hopper?
It's recommended to adjust when the burrs are empty to avoid jamming. Grind through remaining beans, then adjust to your new setting.

What do the numbers on the adjustment dial mean?
Each number represents a grind setting, with lower numbers being finer and higher numbers being coarser. Each click between numbers provides a micro-adjustment. Settings are approximate—you may need different numbers for different beans.

Is this grinder suitable for beginners?
Yes. The numbered adjustment system is intuitive, and the smooth grinding action makes it easy to use. The 36 settings provide room to grow as you refine your brewing technique.
