It's a helpful picture for my Comandante C40 MK4 review.

According to hundreds of baristas and fans, the Comandante C40 MK4 Grinder is the ultimate solution for coffee enthusiasts looking for top-quality grinding on the go. With its durable and reliable design, this hand grinder delivers a consistent and precise grind every time, ensuring you get the perfect cup of coffee no matter where you are.

Still, it isn’t perfect neither for everyone. Keep reading to find out if it’s the right fit for you.

Design & Construction: Elegant, Practical & Durable

While writing this Comandante C40 MK4 burr grinder review, I paid great attention to the design of this grinder. The Comandante C40’s simple and functional design is flawless. Each component fits and works smoothly. When I grind coffee manually with the Comandante C40 MK4, it takes less effort and doesn’t get stuck as most grinders do. It’s light, and all the details look and feel fantastic: the body, the crank, and the grounds container.

The MK4 differentiates from most grinders, even previous Comandante C40 models, because of its customization capabilities. It comes in more colors and textures, and there are beautiful add-ons on sale online from dozens of vendors.

I have tested and used the Comandante C40 MK4 in different colors and finishes, and I personally prefer the wooden textures such as the Liquid Amber and the Virginia Walnut. The texture is delicate but still provides a better grip, in my experience. On the other hand, the painted body makes it more personal and modern. Since previous versions have always come in a wooden finish, many prefer to choose a painted body closer to their preference, which helps build a more appealing setup.

When it comes to built quality, this grinder is great. Hundreds of customers claim it’s incredibly sturdy. And I can’t agree more. The C40 body feels solid, as each component.

Furthermore, I’ve seen its glass reservoir resisting falls from the counter! I can tell from experience. It has happened to me with the Comandante C40 MK3 and with the MK4, too. Each time, I dropped the glass reservoir accidentally, and both containers survived without a dent.

For extensive durability, it is made with a stainless steel body. Its body is wrapped in wood veneer to give it a nice and elegant appearance. Also, the ergonomic handle spins smoothly, and the wooden knob is elegant, making the grinding process much more comfortable and pleasant.

Compact Size & Lightweight

The manufacturer of this coffee grinder kept it compact and easy to handle. Being a hand-cranked coffee grinder, Comandante C40 is lightweight. Hence, it is a portable grinder that you can easily carry around.

Grind Settings – The Famous Clicker

The MK4 has a fairly simple grind-setting process. Its stepped adjustment system changes the grind size after every click (about 30 microns).

There are 40 clicks, which allow you to adjust the grind size. This click system allows you to make refined adjustments to get your preferred grind size settings.

Consistent Grind Size

This particular Comandante grinder offers a high degree of grind consistency. Espresso-style grind size is a measure to know how consistent the grind size is.

The MK4 can deliver coarser to finer grinds depending on your brewing method. Hence it can be a viable choice when you want to have the same great cup of coffee every day.

High-Quality Burrs

The Comandante C40 MK4 comes with high-quality steel burrs. The use of nitro steel helps to retain the sharpness of the edges. In other words, the conical burrs used are highly wear-resistant. In addition, the sharpness of the burrs is there to stay longer than expected.

As a result, you can expect a consistent grind size. The steel surface doesn’t retain the flavor of the coffee beans, as it is highly inert. The burrs are attached to a center axle, supported with micro ball bearings. This makes it an easy-to-use hand grinder.

Performance Evaluation

The Comandante C40 MK4 is capable of offering outstanding grind quality. You can choose between a wide array of grind settings. Whether you grind the coffee beans for Cold brew or Turkish coffee, the grinds are mostly uniform.

With a simple adjustment dial, changing the grind setting is a breeze. The dial is located under the lower side of this grinder. It offers accuracy and lets you grind your coffee for almost every brew method.

Usually, people are concerned about whether a particular grinder suits Espresso. This is the area where Comandante C40 MK4 outperforms the others. It allows you to grind coffee for Espresso and enjoy a perfect-tasting shot.


  • Even grind-size distribution: it offers a good grind-size distribution, as expected for the price. We can’t say is the best at this price point, but it doesn’t disappoint either.
  • Portability: Since Comandante C40 has a compact design, it tends to be highly portable. This feature makes it highly suitable for those who travel a lot. In addition, it weighs only 740g, which doesn’t add much weight to your backpack.
  • Capacity: Irrespective of itssize, the Comandante C40 MK4 grinder offers a generous capacity. It is capable of grinding 40g of coffee at a time. This amount is suitable for brewing up to 6 cups of coffee.
  • Maintenance: Its minimalistic and straightforward design makes maintaining the Comandante C40 MK4 grinder easy. You must brush the burrs and interior of the grinder after a couple of uses. Cleaning the grinder won’t disturb the grind settings.


  • Expensive: Compared with other hand grinders, the Comandante C40 MK4 is higher in price. However, the features like exceptional grind consistency and durability make it worth the price.
  • Slow: This hand grinder isn’t fast at grinding, especially for espresso.

Comandante Grinder Alternatives

The Comandante Coffee Grinder is popular among coffee enthusiasts for its quality and consistency. However, it has a hefty price tag and some limitations for dialing espresso.

Find below some Comandante C40 MK4 alternatives. We have you covered if you want a dedicated hand-grinder for espresso or are looking for a top-quality alternative for a better price.

1Zpresso J-Max: A better grinder for espresso without breaking the bank

Comandante grinder fans claim it offers the micro-adjustments necessary to dial an espresso. However, the 1Zpresso J-Max is better for espresso.

The 1Zpresso J-Max is also more affordable, even with titanium-coated steel burrs with a heptagonal design and external micro-adjustments.

It’s hard to beat the 1Zpresso J-Max with 8.8 microns per click at this price range if you’re after an espresso grinder.
