Comandante C40 MK4 review (2026)
Comandante C40 MK4 is a hand grinder that suits Moka pot, AeroPress, Pour-over, French press and Cold brew. From €231.50 delivered to Germany, prices vary by country.
Reviewers call it the benchmark for filter: very consistent, near-zero retention and built to last. It is costly, and stock espresso is limited without the Red Clix part.

Pros and cons
Pros
- Reviewers describe very even grounds across the whole range, from Turkish to cold brew.
- Build is tough, with a steel body, two bearings and Nitro Blade burrs.
- Retention is near zero: one two-year owner gets almost exactly the dose out.
- Grinding takes little effort, and after two years of near-daily use one owner saw no wobble.
- The MK4 frame removes the MK3 axle hole where beans got stuck.
Cons
- It is expensive, and reviewers say cheaper 1Zpresso grinders now compete on filter quality.
- The 30 micron steps are too coarse for espresso, and reviewers call the optional Red Clix axle close to essential.
- There is no numbered dial, so you count clicks from zero.
- The body is thick, which is hard for small hands, and no cleaning brush is included.
What owners report
- Durability. RoastAroma's owner summary scores durability highest and calls failures rare. A two-year reviewer saw no decline.
- Espresso is a learning curve. Owners say espresso takes learning. Heavy espresso users often move to an electric single-dose grinder.
- Filter owners keep it. Filter-only owners often keep it indefinitely, per RoastAroma.
What experts measured
- Coffeeness timed 19 g in 45 seconds at a mid-range setting, with almost no stalling.
- Coffeeness lists about 30 microns per click, or 15 with Red Clix, a 39 mm burr and a 40 g capacity.
- Coffeeness found only 11 clicks gave a passable espresso on the stock axle, with its other settings too slow or fast.

Is the Comandante C40 MK4 a hand or electric grinder?
It is a hand grinder with conical, stainless steel (Nitro Blade) burrs and stepped adjustment. It is quiet.
Is it worth upgrading from the C40 MK3?
Home Coffee Expert says the burrs are unchanged, so upgrading is not worth it. Coffeeness says the main change is a redesigned inner frame.
Can the C40 MK4 make espresso?
Only with limits. Coffeeness and Home Coffee Expert say the stock axle lacks fine steps, and the Red Clix axle halves the step size.
