The Best Coffee Grinders in 2021

Author: Joanna Davis

Home & Kitchen Expert

The coffee grinders of yesteryear not only looked wonderful and had plenty of style – they also conjured up a scent in our noses that we simply couldn’t resist. If you think about it for a while, you automatically have your grandmother in mind; she’s sitting on the kitchen chair, the coffee grinder on her lap and turning the crank in a good mood.

The wonderful coffee aroma quickly spreads throughout the entire apartment. In the context of a coffee grinder test, however, you quickly realize that the designs now differ significantly among themselves. There are still coffee grinders in nostalgic form for cranking – but there are also fully automatic variants.

Frequently Asked Questions: Coffee Grinders

What is a coffee grinder?

A coffee grinder is used to freshly grind the roasted coffee beans. The resulting ground coffee can then be processed further. According to the comparison test, many coffee grinders now allow you to determine the grind strength yourself.

Functions such as “hand filter” or “coffee machine” determine the fineness of the powder, and this can be very important for the end product in the end; very fine powder is required for espresso machines, as they work with great pressure.

Filter coffee, on the other hand, is better left coarser according to the comparison test. This allows the roasted aromas to develop best.

How does a coffee grinder work?

As the test comparison has shown, the function of a coffee grinder is quite banal. First, the appropriate amount of coffee beans is filled into the appropriate device. Care should always be taken not to overdo it with the filling quantity, otherwise the grinder can quickly become clogged.

Now a crank is turned clockwise or, in the case of the electric variants, the start button is pressed. During the comparison test, according to the team of experts, you could clearly hear how the roasted beans were gently crushed and turned into flour.

Even during this process, the test team enjoyed the emerging coffee scent. Once you feel that all the beans have been sufficiently crushed, you can carefully open the small drawer and check whether the powder is fine enough.

Otherwise, you simply close this drawer again and crank a bit more. According to the test team, you have full control over this.
The system is always the same in principle, but there are different versions of coffee grinders with different grinders.

What are the advantages & use cases of a coffee grinder?

As the test clearly confirmed, a certain thesis can be stated at this point with a clear conscience: “The more exclusive the existing coffee machine is, the higher the quality of the coffee grinder should be in the end”.

The following areas of application are possible:

As a grinder for high-quality coffee machines (portafilter…).
This phenomenal coffee machine deserves to get the desired coffee grounds from the grinder of a high-quality espresso grinder. According to Comparison Test, this is around a UK price of around 200 euros. The cheaper alternative is the Graef CM 800 coffee grinder, which is almost perfect for beginners.

According to the comparison test, this coffee grinder does not offer a stepless grind adjustment, but the grid is fine. Furthermore, the coffee grinder is very quiet. Next to the portafilter, it does quite well and it doesn’t steal the show from it – on the contrary; it ensures delicious coffee enjoyment through its functions.

Grind coffee grounds in advance
According to testing, there are some people who don’t necessarily have a tremendously high-quality coffee maker, but rather use inexpensive versions, and yet are reluctant to buy their coffee directly in powder form. They want to grind the whole beans themselves at home so as not to miss out on the fresh flavors.

In this case, the ground coffee is produced in advance with the help of a small grinder and then stored in a large coffee can. If necessary, some is always taken out.

Similarly to the coffee maker itself, according to the comparison test, an inexpensive coffee grinder is completely sufficient here. Often, however, according to the customer reviews of external product and comparison tests, these people also use combined automatic coffee machines with a percussion grinder. These variants are quite cheap to buy. In this way, the coffee beans are still freshly ground and then brewed directly into coffee. The respective amount is portioned as desired and according to the test, everything is available from one source.

For quiet connoisseurs
There will probably always be them, and that’s a good thing – the espresso lovers who prefer to enjoy their coffee with Italian flair. They have acquired a small, mostly silver hand filter espresso machine that they can operate manually. For this, they need a coffee grinder that can grind a little finer. Nostalgia is also the name of the game in this regard, as the small coffee grinders with a retro look are very popular there, according to Comparison Test.

The tiny drawer compartment is perfectly adequate, because only a modest amount of coffee beans is ever freshly ground – just for that little cup of espresso. The Brésil coffee grinder from Peugeot would be a good choice according to the comparison test. It also even has a grind setting function.

Fully automatic coffee machine with coffee grinder
Everything from one source is the motto here; first you fill in the coffee beans at the top and at the end you get the finished hot beverage in the strength of your choice at the bottom.

According to the comparison test, the Philips 5000 EP5335/10 is an excellent choice, because it not only looks good in its stainless steel design – it also delivers versatile coffee variants with latte macchiato, cappuccino and espresso at the touch of a button.

What types of coffee grinders are available?

Grandma's old coffee grinder

According to the coffee grinder comparison test, the FRENCH-PRESS, CHEMEX and several other models are equally suitable; they can be operated manually by hand, allowing you to perform all the preparation steps yourself.

It’s like driving a car; there are those who celebrate every technical advance and those who prefer an old VW bus without automatic and power steering. Old often has much more charm – there are still so-called “vintage coffee grinders” that are more than 100 years old and there are even companies that have made it their business to refurbish them. So there are two types of grandmother’s coffee grinders:

  1. coffee grinders that are actually that old.
  2. retro coffee grinders, intentionally designed as if they were from that time.

The advantages of the first variety:

  • captivatingly beautiful appearance in wooden design
  • rarity value
  • equipped with excellent cone grinding mechanism
  • high-quality wood instead of plastic
  • old craft; you can feel the grinding.

The disadvantages:

  • grinding degree adjustment impossible
  • coarser grind
  • coffee powder must first be fetched from wooden drawer
  • difficult to clean
  • rather for collectors or rare coffee drinkers.

Coffee grinder with integrated impact grinder

As the comparison test has shown, the type of coffee grinder depends on its grinder, because this is the heart on which all responsibility hangs. For example, if too much frictional heat is generated during grinding, the aroma is lost and the coffee ends up with a bitter note. A good grinder should work homogeneously.

The advantages:

  • Standard grinder of most inexpensive coffee machines.
  • you save money.

The disadvantages:

  • works very inaccurately
  • irregular grind
  • heats up quite quickly
  • coffee sometimes tastes bitter
  • not good quality of the coffee powder.

Coffee grinders with disc mill

According to the comparison table of a product or comparison test, these coffee grinders consist of a grinder with two discs and a kind of elevation. Strictly speaking, these discs are concave in shape, i.e. curved inwards. They are arranged one above the other and run closer and closer to each other towards the outside. While the lower disc is fixed and does not move, the upper one rotates.

Finally, according to the comparison test, the whole principle of this coffee grinder is based on this; the coffee beans get between these two discs during the grinding process and are driven from the inside to the outside by means of centrifugal force.

This gradually refines the grind. According to the test, the desire for coarser coffee powder can be quickly fulfilled with such a coffee grinder; the distance between the two discs simply has to be changed via a regulator! A product test is therefore not only a suitability test or examination or analysis, but also always a small experiment.

The advantages:

  • adjustable grinding degree
  • robust stainless steel is used or minimally vulnerable ceramics
  • long service life
  • continuous grinding process
  • homogeneous degree of grinding.

The disadvantages:

  • higher number of revolutions during the grinding process
  • quite high frictional heat
  • possibly bitter coffee product.

Coffee grinder with cone grinder

Even if, according to the test, all coffee grinders are ultimately in some congruence with each other, such a coffee grinder is already a gift compared to the others. Most product tests come to a similar conclusion.

The test result, or rather the test grade, is correspondingly good. It is therefore not enough to compare coffee grinders only visually – in this respect, the similarity is often great.

A close inspection of the grinder itself is clearly the focus of the comparison test to determine a comparison winner. Thus, quite a lot is tested so that at the end of the test run, a comparison of the products succeeds in the form of a table that consumers can easily orient themselves by.

The advantages:

  • gentle grinding process
  • low rotational speed
  • no overheating
  • low friction energy
  • coffee varieties do not become bitter
  • adjustable grinding degree
  • homogeneous grind.

The disadvantages:

  • great differences in quality between models
  • cheaper variants are usually equipped with weak motor
  • in this case low torque
  • strong frictional heat.

Handmade coffee grinders

Of course, they are not made by hand, but they are manually operated. In the comparison test, supporters of this variant also appeared from time to time among the customer reviews, who consider brewing coffee a fixed ritual. Of course, grinding coffee is an essential part of this – in this case, doing it by hand is like paying homage to this popular hot beverage and you don’t give up control. Even for most campers, a hand-operated coffee grinder has long been part of the fixed repertoire, according to Comparison Test.

The advantages:

  • no electricity is needed
  • it is pleasantly small
  • it needs hardly any space
  • very affordable
  • High-quality variants are partly equipped with a cone grinder and the grinder grinding degree is adjustable.

The disadvantages:

  • can be exhausting under certain circumstances
  • grinding takes a little longer
  • rather suitable for small quantities, since quite elaborate.

How are coffee grinders tested?

In order to test products like this intensively, a practical test is basically part of the process. After all, a comparison test is not just a theoretical study. A good evaluation is also based on a test, at the end of which, in the best case, there is a sample of the coffee beverage itself. A completed product and comparison test is based on a juxtaposition of the tested coffee grinder models from different manufacturers.

Thanks to the clarity and clear structures, consumers can thus look for matches in a relaxed manner and, if necessary, provide themselves with the available information.

A consideration of which of the listed products is ultimately the right one for the personal purpose can thus be made quickly. Of course, certain criteria and attributes are defined in advance, according to which the test is carried out in the first place:

The type of the respective coffee grinder

  • electric
  • manually operated

The grinder used

  • Impact grinder
  • disc grinder
  • cone grinder

The functions

  • adjustable grind yes or no
  • manual or electric

The weight and dimensions of the coffee grinder

  • light
  • heavy
  • small & compact
  • large & bulky

The material of the coffee grinder

  • wood
  • stainless steel
  • plastic

The price-performance ratio

  • Are the functions, the material and the operability in a balanced relation to the price or rather not?

Coffee grinders are explicitly about filling whole beans at the top and actually creating coffee powder at the bottom. The way to get there is the interesting part, because it’s all about the quality of the product; after all, not all powders are the same!

What else should I look for when buying a coffee grinder?

Manual coffee grinders

According to the comparison test, they cost a bit more power, but also much less money – moreover, they are highly recommended overall. The coffee powder is of high quality, especially in the models with adjustable grind. For this reason, you should prefer those grinders that are equipped with it.

Electric coffee grinders

They are more expensive than hand-operated variants, but you get the finished coffee powder at the touch of a button – so without any muscle power!
According to the comparison test, however, you should definitely pay attention to the grinder used when buying:

  • Impact grinders; are indeed cheap, but not at all recommended. They grind much too inaccurately and generate a lot of heat during the grinding process. The result is quite coarse and irregular powder and bitter coffee.
  • Disc grinders work much more esignificantly more precise and are very popular with espresso lovers, according to the comparison test. The strength of the ground coffee or the degree of grinding can be regulated by changing the respective distance between the discs.
  • Cone grinders are the crème de la crème among grinders. They work precisely and almost no heat is generated during the grinding process. But beware: This is only true if the motor is of high quality and not too weak!
  • Homogeneous grinding is a guarantee for high-quality coffee.
    According to comparison test, it is basically advisable to find out exactly before buying a coffee grinder and to take this fact into account when making a purchase decision. You will be rewarded with delicious coffee in the end.

Coffee Grinder Accessories

  • Small cleaning brush; according to the comparison test, it can also be used to get into the gaps and remove powder residues without any problems, especially on the antique coffee grinders.
  • Coffee grinder brush; with it, powder residues can also be removed well, without damaging sensitive materials.
  • Coffee grinder cleaner; this product cleans free-standing coffee grinders gently and reliably. According to test comparison, this purchase is very worthwhile.
  • Attachable bean hopper; there are compatible attachments for various coffee grinders. In some cases, the filling quantity can be increased.
  • Cleaning granules; according to the product test, this cleaning agent is perfectly suitable for the inner part of the coffee grinder.
