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.

• Pour-over coffee (e.g., V60, Kalita, Chemex)

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.

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.
