TIMEMORE Chestnut C3S Manual Coffee Grinder, Stainless Steel S2C Conical Burr Coffee Grinder, Hand Coffee Grinder, Adjustable Grind Setting for Travel/Camping/Home, Black

A dependable manual coffee grinder is an essential tool for coffee drinkers who want freshly ground beans at home or while traveling without relying on an electrical outlet. The TIMEMORE Chestnut C3S provides a durable all-metal aluminum alloy body designed to withstand frequent daily use. By building both the exterior and internal structure from aluminum alloy, it protects the internal components against physical impact and helps dissipate friction heat during longer grinding sessions so delicate bean flavors stay protected.

Grind quality centers on the patented S2C660 conical burr set, which is manufactured from 5-axis CNC-machined steel with a hardness rating of 55-58HRC. This hexagonal cutting profile cuts coffee beans evenly, minimizing unwanted fine dust and virtually eliminating excessively coarse particles. As a result, you get a uniform particle distribution that supports balanced flavor extraction across different brewing styles.

Using the grinder requires surprisingly little effort thanks to its mechanical layout. An internal bearing ensures smooth rotation, allowing the handle to continue spinning briefly on its own momentum after you release it. The main cylinder measures 52 mm across, making it easy to hold securely even for smaller hands. An adjustment nut lets you dial across roughly 36 coarseness settings: turn clockwise for a finer powder or counter-clockwise for a coarser grind.

Because this is a completely manual unit, you supply the physical effort for every cup, which can take time if you are preparing large batches. The compact 52 mm profile and integrated folding handle make it convenient to slip into luggage or camping gear, but routine maintenance requires disassembling the parts and sweeping away grounds using a brush rather than rinsing components under tap water.

Verdict: The TIMEMORE Chestnut C3S manual coffee grinder is an excellent option for single-cup brewers, travelers, and campers who prioritize uniform particle size and sturdy metal construction over electric speed. Shoppers who regularly brew full pots for groups will likely prefer an automatic electric machine instead.

• Body Material: Full metal aluminum alloy

A great fit if you:

• Want a durable metal hand grinder with a 52 mm diameter that is comfortable to hold and turn.
• Appreciate an adjustable nut with roughly 36 coarseness settings to shift smoothly from fine to coarse grounds.
• Need a portable coffee tool with a folding handle that packs easily into bags for camping trips or vacations.
• Rely on precise conical steel burrs with 55-58HRC hardness to produce consistent grounds with minimal fines.

Consider something else if you:

• Brew multiple large carafes of coffee daily and prefer the rapid, push-button operation of an electric grinder.
• Prefer kitchen gear that can be washed under running water instead of being cleaned strictly with a dry brush.

Confirm on the listing:

• Check whether a cleaning brush is included in the package or if you need to supply your own.
• Confirm the hopper and grounds container capacity in grams to see if it matches your usual batch size.
• Review the total weight and folded dimensions if you have strict packing limits for your travel gear.
• Check the included user guide to confirm the recommended click ranges for your preferred brewing methods.

How to compare your options: Focus on burr material, body build, and adjustability when weighing manual coffee grinders. This model features an all-metal aluminum alloy body, a 52 mm grip, and hardened S2C660 steel burrs with approximately 36 adjustment clicks. Look closely at how other manual options handle portability, burr stabilization, and cleaning requirements before settling on the right companion for your brew routine.

Read any included instruction manual before using the grinder for the first time to familiarize yourself with the internal parts and the adjustment nut mechanism. Always turn the adjustment nut clockwise to move toward finer settings and counter-clockwise for coarser grounds, counting your clicks carefully so you can reliably return to your favorite recipes.

Hold the 52 mm aluminum body firmly with one hand while cranking the folding handle with the other. The internal bearing will keep rotation smooth and steady, requiring minimal force to feed beans evenly through the conical burr.

For routine maintenance, disassemble the components carefully and clear leftover coffee grounds using a dry brush. Do not wash the metal burrs or internal components with water, as keeping them dry preserves the metal assembly and ensures consistent performance over time.

How do you adjust the grind size on this grinder?
You adjust coarseness by rotating the adjustment nut located on the burr assembly. Turning the nut clockwise produces finer grounds, while turning it counter-clockwise creates a coarser grind across approximately 36 settings.

What burrs are installed in the TIMEMORE C3S?
It features patented S2C660 hexagonal conical burrs. These burrs are crafted with 5-axis CNC machining and offer a hardness rating of 55-58HRC to ensure uniform cuts and minimize fine powder.

Can I wash the grinder with water?
No, the manufacturer indicates that it should be disassembled and cleaned using a brush. Washing it with water is not recommended for maintaining the internal metal parts.

How wide is the grinder body?
The body has a compact diameter of 52 mm, which is engineered to be easy to hold securely even for users with smaller hands.

How much coffee does the hopper hold at once?
The listing does not state the exact bean or grounds capacity in grams. Check the current product description or package specifications if you require a specific capacity per grinding cycle.
