Comandante grinder review

The argument about which is better between manual or electric grinders has been going on for a while among coffee drinkers. While most casual coffee drinkers and some committed coffee drinkers stand by their electric grinders, coffee experts tend to go with the manual grinder.

The Comandante manual grinders, however, have an even higher standing among coffee connoisseurs than other manual grinders. This is as a result of the level of detail that goes into the manufacture of their grinders. They are designed to offer simple yet precise service.

Overall performance and functions

Overall, very few complaints about the functioning of this grinder can be observed when reading through customer reviews. The stepped grind adjustment system utilized by the Comandante is also very easy to use.

Despite the inconvenience expected of manual grinders, this coffee grinder still offers convenience areas. For starters, the grinder retains its adjustment settings even after it is disassembled for cleaning. It is also faster and smoother in its operation than its predecessor, the MKII.

It helps the reputation of this grinder that even with its widely acclaimed durability, there are still readily available spare parts for when a part of the grinder develops a problem.

Comandante Grinder ReviewType

The type of grinder to purchase is always a matter of personal preference. Generally speaking, manual grinders are less convenient than electrical grinders, but they have also been praised for helping to retain flavor better.

Furthermore, coffee drinkers have claimed to be more satisfied with a brew made from manually ground coffee. An extra advantage to using the Comandante manual grinders is that the complaints of imprecise grind settings that trail the functioning of the electrical grinders are moot here.

The manufacturers of the Comandante grinder pride themselves on the single-minded dedication to producing a quality grinder.

Grinding speed

Compared to electric grinders, manual grinders are slow. Among manual grinders, though, the Comandante C40 MKIII grinder is not particularly slower or faster. It grinds at an average speed of 1 coffee bean per turn, but it should be noted that the speed of grinding would vary with the type of coffee required. As such, finer coffee should take longer to grind.

The emphasis on the grinding speed should, however, not detract from the main selling points of this product, which are the homogeneity, consistency, and quality of the grind it produces.

Burr material

The material used in making the burr of this Comandante C40 MKIII grinder was settled upon following extensive research. The level of study that went into the choice is evidence of just how committed the manufacturer of this coffee grinder is to quality.

The burrs are made from high-nitrogen martensitic stainless steel. These are quite difficult to work with compared to other metals due to its hardness, but it is less prone to wear and retains its sharp edges better. As such, the burr is sharper and more durable.

The production of this burr is therefore not very easy, but its effectiveness and durability are worth it. The effort and craftsmanship that goes into its production are, however, one of the reasons for the relatively high cost of this manual grinder.

Comandante Grinder ReviewBurr’s hardness level

As stated earlier, the burrs are made from high-nitrogen martensitic stainless steel. These are quite hard and are very durable as well. This hardness is represented formally by a hardness of approximately 58 on the Rockwell scale.

The burrs are not just hard, though; they are also very sharp and corrosion-resistant. Their corrosion resistance lends more durability to them, and the fact that they are not as prone to wear as other materials means they retain their sharp edges for longer periods compared to burrs made from other metals.

Knob material

The knob of the Comandante C40 MKIII grinder is made from oak wood. The wood is popularly obtained from Germany’s black forest, and the finishing of the knob is stylish enough to be regarded as artistic by some. It is precisely designed and weighted to be comfortable and is shaped with the same ideas in mind.


The Comandante C40 MKIII grinder is very lightweight and compact. The grinder weighs about 8 ounces and is okay for its grinding capacity. Due to this, the grinder is widely considered to be portable enough and light enough to serve as a coffee grinder for trips and the likes.

The lightweight nature of the grinder could be attributed to the limited use of metallic parts in its design.

Durability and warranty

The materials used in making the Comandante grinder are very durable. From the martensitic stainless steel used for the burr to the oak wood knob and wooden finishing (or metal) of the body, the grinder is designed for long-term service. The most fragile part of this coffee grinder is the glass grinds catcher but provided the grinder isn’t dropped or handled carelessly, and this should be okay as well.

The durability of the Comandante is also enhanced by the relative ease with which it can be maintained. The simplicity of its design means that disassembling it is quite straightforward. Once disassembled, a soft brush could be used to wipe the burrs to remove coffee grounds that may have stuck to them.

Price tag

Purchasing this Comandante C40 MKIII coffee grinder is a sound step towards brewing quality coffee. However, quality coffee is costly to make, and the grinder is not very cheap compared to other available grinders.

The grinder, however, offers high-quality service and durability that is almost unmatched in the market. It is effective grinding for Turkish coffee as it is for French press, and the quality of the materials utilized in its production guarantee that it would still be in use for quite a well.

As such, though the purchase price might be discouraging, this coffee grinder is a must-have for coffee enthusiasts. And if you’re a newbie to grinding and brewing your coffee, you could still purchase this to spoil yourself with quality coffee.

Key features

The Comandante C40 MKIII coffee grinder utilizes a state-of-the-art burr design and complements that by using high-end materials in the manufacture of the burr. This contributes greatly to the effectiveness of its grinding process and the durability of the grinder. As such, if the goal is to buy a quality manual grinder that would maintain its effectiveness for a long time, the Comandante C40 MKIII should be a good choice.

That aside, it should be noted that the grinder still has its flaws. The pros and cons of the Comandante grinder are outlined below:

Pros Cons
The grinder is less noisy than electric grinders It is relatively expensive compared to manual grinders of similar capacity
It provides consistent grind quality It doesn’t have a large grinding capacity
It is portable and light enough to be carried along on trips
It is very durable


It is not easy to avoid waxing on and on about this coffee grinder. It has a lot to offer in terms of efficiency and effectiveness. And though it might be of a smaller grinding capacity than other popular manual coffee grinders, it holds its own in terms of quality.

I have tried to express the satisfaction you would enjoy from using the grinder in this comandante C40 MKIII coffee grinder review. Still, you would only really appreciate the round goodness of this Comandante after you have used it. So, purchase one too and significantly up your coffee brewing game.
