MiiCoffee D40+

Equipment notes

The D40+ is a single-dosing electric grinder from the coffee-gear brand MiiCoffee, using 40mm conical steel burrs. It is motor-driven with stepless adjustment for fine control of coarseness, and its forward-tilted aluminum body and blow-out design are built to reduce retention. It offers a single-dosing experience at an entry-level price. Conical burrs carry a body-preserving particle character, and stepless adjustment helps with brews that need fine coarseness changes, such as espresso dial-in. The low-retention design suits grinding small amounts while switching between beans, and its range centers on espresso while extending to filter and French press. It suits espresso beginners who want to start single-dosing, grinding one fresh dose at a time, on a modest budget.
