The hand grinder that every other hand grinder is measured against.
The Comandante C40 is the reference standard for hand grinder quality. Made in Germany with proprietary high-nitrogen stainless steel burrs, the grind consistency at espresso settings is among the best of any grinder at any price. The MK4 version refines the adjustment mechanism and adds Red Clix (an optional accessory that doubles the number of adjustment steps for espresso). The build quality is impeccable — solid walnut, stainless steel, glass catch jar. It's also the hand grinder of choice for specialty coffee professionals worldwide, which tells you everything about the quality.
Any machine — the C40 won't be your bottleneck
You want the best hand grinder money can buy, full stop. The C40 is the grinder that specialty coffee professionals use for cuppings and competitions. It's expensive for a hand grinder, but the grind quality rivals electric grinders at 2-3x the price.
