How we test coffee grinders

Ground coffee

We purchase bestselling coffee grinders from leading UK retailers and put them through tough tests to find the best. We regularly revisit the coffee grinders on sale to see if there are any more popular models that need testing - and when we find them we do.

Find out more about how Which? is not influenced by product manufacturers or retailers and how your support helps us to stay editorially independent

Grind quality

Coffee bean grinders often have several grind settings to choose from, as different coffee makers require differently sized grounds. A cafetiere, for example, needs a coarser grind, whereas an espresso requires very finely ground coffee.

  • We buy fresh coffee beans, as well as pre-ground coffee in coarse and fine sizes from the same brand, for reference.
  • We use this specialist coffee sieve and guide to measure how much ‘perfect’ espresso and cafetiere coffee each coffee grinder produces, as shown in the image below.
  • We mark machines down that produce too much coarse coffee for espresso and too much fine coffee for a cafetiere.
  • We use a weighing method to give an objective assessment, which is unlike other coffee bean grinder reviews that take a more subjective approach.

Ease of use

It should never be complicated, uncomfortable or difficult to use your coffee grinder. It should be simple to load up your coffee beans and get the perfect grounds you're looking for.

When using each coffee grinder, we assess the following: 

  • The build quality, praising stable designs, clear labelling and the presence of lid locks and non-slip bases. 
  • The size and weight, and how easy or difficult it would be to store each coffee grinder.
  • How easy it is to load up the bean hopper with coffee beans (the hopper is the storage tub on top of the grinder). 
  • How easy the controls are to set the grinder and run.
  • How easy it is to empty out the grounds.
  • How easy it is to clean the grinder after use.

Noise

Grinding coffee beans is often a loud process, but some grinders are excessively noisy and irritating during use. 

We rate each grinder on how loud and annoying they are, with quieter machines earning higher ratings.

Versatility 

We reward the machines that have a higher number of settings and more options to customise your coffee grounds.

What is the best coffee grinder to use? 

A precise, even grind is essential for making tasty coffee at home. Choose a poor coffee grinder, and you may end up with uneven grounds and a badly extracted, watery brew.

  • To make espresso, either in a traditional coffee machine or using a stove-top pot or portable coffee makers such as an AeroPress, you'll need fine-ground coffee.
  • To fill up your filter coffee maker, you need medium grounds.
  • If you want to make black coffee in a filter machine or cafetiere, you'll need a coarser grind.

There are three main types of coffee grinder:

  • Electrical blade
  • Electrical burr
  • Hand grinder

Which one is best for you depends on what type of coffee you like to make, how much you make, and whether you want the flexibility of being able to achieve different grounds tailored to different coffee types.

Blade coffee grinders

Blade grinders (like the one in the picture below) have a spinning blade inside that cuts the beans into smaller pieces, similar to a blender. 

Pros of blade coffee grinders

  • Relatively simple and inexpensive

Cons of blade coffee grinders

  • Blade heats up coffee as it chops the bean, which can alter the flavour
  • Doesn’t produce a consistent fine grind, not ideal for espresso

See which model we named the best filter coffee machine.


Burr coffee grinders

Burr coffee grinders have a small gear-like mechanism inside that crushes coffee beans to produce ground coffee. Because they crush rather than chop the beans, they don’t exert the same kind of force and heat that a blade grinder might. 

The image below shows the difference between grounds from an electric blade grinder (left) and a burr coffee grinder (right).

Coarse vs fine coffee grounds

Pros of electric burr coffee grinders

  • Can produce a more consistent, fine grind for making espressos and also the rougher grounds needed for filter coffees and cafetieres, making them a more versatile option if you drink different types of coffee
  • Can grind larger amounts in one go
  • Often have multiple grind levels for different coffee types

Cons of electric burr coffee grinders

  • Tend to be more expensive than a basic blade or hand grinder

Hand coffee grinders

Hand grinders grind coffee thanks to your own arm muscles. Most hand grinders come with a burr in them, which is a cheap way to get a good-quality grind for your espresso coffee maker.

If you're only grinding small quantities at a time, they can be a good option, as you have total control over how much you want to grind. Most electric coffee grinders grind a minimum of two cups of coffee at a time.

Pros of hand coffee grinders

  • Basic models are very inexpensive
  • Burr models can grind fine espresso grounds for less
  • Not as noisy as electric grinders
  • Take up less space

Cons of hand coffee grinders

  • Can usually only grind small portions of coffee at a time
  • Take some physical effort

Flat vs conical burrs

You may see coffee aficionados extolling the virtues of either a flat burr (pictured below left) or a conical burr (pictured below right).

Flat vs conical burr coffee grinders
  • Conical burrs grind beans into two slightly different particle sizes, which works particularly well in espresso machines.
  • Flat burrs should grind the beans into a consistent fine grind, which may sound better in theory, but the fine grind produced by a flat burr is trickier to get good, consistent results with when making coffee.

Also, flat burr coffee grinders will usually be much pricier than their conical burr counterparts. For most people, a coffee grinder with a conical burr is going to be good enough for the job of grinding beans for your coffee machine.

Steel vs ceramic burrs

  • Steel burrs are usually found in widely available coffee grinders sold in big retailers such as John Lewis and Lakeland.
  • Ceramic burrs are less common, but can be found on some hand grinders.

Both of these materials will handle grinding the coffee beans equally well, the main difference being in the durability of the grinding burr.

A ceramic burr is likely to last longer than a steel burr, provided that it doesn’t encounter any rogue materials, such as a small fragment of stone, that could cause it to chip.

Stepped vs stepless grinders

A stepped coffee grinder will have pre-set grind options for you to choose from, from a fine to a coarser grind. Most electronic burr coffee grinders in retail shops such as John Lewis or Argos will be stepped.

If you really like to be adventurous with your coffee, you might consider a stepless grinder. To get your hands on one you'll have to venture off the high street and you’ll be spending quite a bit more money too. A stepless grinder has no pre-set grind levels. Instead, you can tinker with it to produce the exact grind you want. While a stepless grinder can offer you even more options for customisation, it does require an experienced hand to get good results.
