Premium Construction, Exceptional Performance

Producing consistently ground coffee over and over again is a tall task for a coffee grinder, but the Comandante C40 MkIII isn’t your average hand mill. It starts with its stainless steel body, axle, crank, and ball bearings for durable construction, and all leads to Comandante’s very own high-nitrogen martensitic steel burrs. The results are pristine coffee grounds that you can rely on, and the care put into the body and burrs of the grinder means that you can trust the C40 MkIII to hold up for years to come.

Beautifully Designed

Don’t let the practical mechanics fool you, this hand grinder doesn’t need you to sacrifice fashion for function. The oak handle is sourced from the Black Forest, and the stainless steel body comes wrapped in a wood veneer available in six striking styles—Wenge, Bamboo, Red Sonja, American Cherry, Black, and Zebra. Add your choice of clear or brown glass grinds catch to the mix and you’ve got a grinder worth displaying proudly in any environment.

A Hand Grinder For Any Need

With a wide range of grind settings available you can trust the C40 MkIII to perform for Turkish coffee, cold brew, and everything in between. Thanks to its stepped grind adjustment you can also be certain that once you find a setting you love you’ll be able to go back to it whenever you’d like.

"Grinds so consistent! The coffee I make every morning with my Chemex tastes even better! Worth the investment."

—Regina A, Verified Buyer

"The body of the grinder fits comfortably in the hand, I wear a size large glove for reference, and the ball bearing in the grindshaft allows very smooth turning of the handle. The stepped adjustment mechanism works well and I haven't had any issues thus far with it going out of its setting."

-Michael B., Verified Buyer

"This grinder seems to be very solidly built (heavier than I expected) and produces very evenly ground coffee. I usually make pour-over coffee, and it only takes 30 seconds or so to grind the beans I need for a cup."
