## Long description

The Manual coffee grinder COMANDANTE C40 MK4 Lab Series Hammerhead Stone Washed is a hand-operated burr grinder engineered for precise, repeatable grinding of roasted coffee beans. Its MK4 Lab Series Hammerhead burr set provides a controlled particle distribution suitable for a range of brewing methods, while the stone-washed finish offers a durable, low-glare surface. The grinder is compact and portable, designed to deliver consistent grind sizes from fine to coarse without electricity, making it suitable for home use, travel, and specialty brewing applications where manual control is preferred.
Advantages
The COMANDANTE C40 MK4 features high-quality hardened steel burrs that maintain sharpness and deliver uniform extraction. Its stepped adjustment system allows accurate and repeatable grind settings across a wide range of sizes. The hand crank and ergonomic handle provide stable, controlled rotation and reduced wrist strain during use. The robust body and stone-washed exterior resist wear and hide minor surface marks, supporting long-term reliability and consistent performance.
Suitable for
Pour-over coffee (e.g., V60, Kalita, Chemex)
Immersion brewing (e.g., French press, AeroPress with coarse settings)
Travel and camping where electrical grinders are unavailable
Home baristas who require precise manual grind control
Key specifications
Burr type: MK4 Lab Series Hammerhead hardened stainless steel burrs
Operation: Manual, hand-crank mechanism
Adjustment: Stepped grind adjustment for repeatable settings
Finish: Stone-washed exterior for reduced glare and improved scratch resistance
Capacity: Suitable for single to multiple cup grinding per session (compact hopper)
Portability: Compact and lightweight design for travel
How to use
Fill the hopper with roasted coffee beans and attach the handle. Set the stepped adjustment to the desired grind size then rotate the crank at a steady pace to grind. Periodically check the grind consistency and adjust the setting if necessary to match the chosen brewing method. Empty the ground coffee from the catch cup and proceed with your preferred brew technique. For consistent results, use the same grind setting and bean dose each time.
Usage recommendations
Clean the grinder periodically by removing loose grounds and wiping the burr area with a dry brush. Avoid prolonged exposure to moisture; if the exterior becomes wet, dry it thoroughly to maintain the stone-washed finish. For the best extraction, pair the COMANDANTE C40 MK4 with freshly roasted beans and adjust grind size according to brew time and extraction taste.
