For maximum flavor coffee should always be bought in bean form and ground.  The coarseness of the required grind depends on the type of brewer used.  For instance, a French press uses coarse grounds, whereas an espresso device uses fine.

As a passionate drinker and consumer of coffee for over thirty years, I can say for certain that grinding your own coffee, rather than buying ready ground, is one of the essential ways to achieve high quality coffee drinks.

For those people who have little or no experience of the different types of grinder however, the variety of products on sale can be confusing, with expressions such as blade or burr meaning nothing to the average person.

Below is a summary of the main different types of grinder for coffee and a blade grinder vs burr grinder comparison. Hopefully, you will find that the technicalities are nowhere near as difficult as you thought.

I will explain the three main types of grinder (the wheel burr grinder, conical burr grinder and blade grinder), including which type are considered the most accurate, which are considered the messiest, which are considered the quietest, and last but not least, which types of grinder are generally the cheapest and most expensive.

I will also give examples of specific models on the market that I can personally recommend.

To me, the smell of fresh-made coffee is one of the greatest inventions.

Blade Grinders

Blade grinders are generally the most inexpensive type of coffee grinder.

As their name suggests, they use a blade to cut up the coffee beans. The blade spins very quickly and looks a like a propeller. It slices the beans into smaller and smaller pieces.

The fineness of the ground coffee is controlled by the length of time that you grind the coffee beans for. This makes them less precise than burr machines, as uneven sized coffee grounds can result, giving a slightly less consistent drink quality.

The heat generated by the rapidly revolving blades can also affect the taste.

These machines are also relatively noisy, when compared with burr and manual grinders.

If you just want something straightforward for a low cost that does the job and doesn't take up much space, this type of grinder will satisfy the majority of coffee lovers. They are excellent for small kitchens and office spaces.

My Favorite Blade Grinder: The Krups F203

I use a Krups F23 in my home office. They are ideal for a small kitchen, or work area. I would also recommend a Krups for coffee lovers on a tight budget.

Advantages

  • Inexpensive
  • Don't take up much space.
  • The 200-watt motor is fast and gives you a quick grind.
  • You can use the Krups for spices, herbs, nuts, as well as coffee.
  • Easy to clean.
  • Reliable, tough and long-lasting in my experience.

Disadvantages

  • Noisy. If someone is sleeping nearby, it will awaken them.
  • Relatively messy when compared to my burr grinder.
  • The fineness of the grind depends on how long you press down. It takes some experience to learn the required optimum for your coffee maker. For example espresso makers require very fine grounds and French presses need much coarser.

I like cappuccino, actually. But even a bad cup of coffee is better than no coffee at all.

Grinding is an essential part of the coffee-making process for those searching for the perfect beverage.  The coarseness of the grounds varies according to the type of maker that is used for brewing.

I don't know how people live without coffee, I really don't.

Burr Grinders

This type of grinder works by crushing the coffee beans against a static surface with a grinder wheel. The coarseness/fineness of the coffee grounds is set by the position of the burr.

This effectively means that you can dictate the size of the coffee grounds much more accurately and consistently than with a blade grinder.

Burr grinders typically have multiple settings, allowing you to choose the appropriate coarseness required for your coffee maker.

There are two main types of burr grinder: those with flat grinder wheels and those with conical grinder wheels.

Wheel burr grinders generally cost the least out of the two.

They have two main downsides when compared to conical burr machines, however. The first one being that they can be loud, due to the wheel, which rotates extremely quickly; and the second problem is that they are relatively messy.

They are still generally superior to blade grinders in most respects, however.

Conical burr grinders are generally accepted to be the best type of grinder available, but they are also the most expensive.

Because they can work at a slower speed, you don't get the heat problems that you can get with a blade machine.

They don’t create as much noise as wheel burr grinders and make less mess, as the grinder doesn’t need to work as fast.

You can also grind oilier coffee beans without worrying so much about clogging up your machine, which can be an issue with other types of grinder.

My own Capresso Infinity.  After going through numerous grinders, I settled on this one.  Quiet and accurate, its conical burrs do their job accurately and efficiently.  After over six years, I've had virtually zero issues with this machine.

My Favorite Burr Grinder: The Capresso 560.01 Infinity

This is the main grinder that I use on a day to day basis. Unlike some of the other grinders I've owned or used, this machine has shown itself to be a reliable and efficient performer over time.

Advantages

  • 16 grind settings, so if you drink different styles of coffee like me, it's easy to use.
  • The built-in timer is very straightforward.
  • Advanced and long-lasting conical burrs.
  • Quiet compared to most other motorized machines.
  • The bean hopper is big enough to handle up to 8-1/2 ounces of beans, more than enough for any situation I've encountered.
  • Reasonably priced.

Disadvantages

  • Fiddly to clean inside and out. I have the black version, but would buy the stainless steel version if I had another choice, both for the sake of appearance and for cleaning the outside.
  • The black dot used to set the coarseness was never easy to see at a glance, but now has faded over time making it harder to tell the setting.
  • Some grounds tend to get retained then spill out onto the counter.

Once you wake up and smell the coffee, it's hard to go back to sleep.

For the freshest and tastiest beverages, it is best to buy your coffee in bean form and grind it straight before you brew.  Your beans need to be stored correctly too, if you want your beverages to have maximum flavor.

Manual Grinders

Most modern types of burr grinder are electrically powered, but there are also some manual grinders available on the market.

These types of grinder generally work by the operator turning a crank. The size of the grounds is dictated by how long you grind for.

There are a number of advantages with owning a manual grinder. Firstly you don't need a power source, so you can use them outdoors, or when traveling. They are also very quiet to operate and often relatively inexpensive to buy.

Manual grinders can also look more attractive than their electrical counterparts, especially those with a vintage or exotic design, and can make a good talking point at social events.

My Favorite Manual Grinder: The JavaPresse

The sleek and sexy JavaPresse is my chosen grinder for travelling, hiking, or outdoors. It is head and shoulders above the average manual grinder and it doesn't cost the earth to buy.

Advantages

  • Looks beautiful.
  • No power source or batteries needed, so you can use it anywhere you go.
  • Unlike many more basic manuals, there are click settings so that it's easy to get the right coarseness of grounds for your coffee maker.
  • No motor so it's quiet.
  • The burrs last longer than blades.

Disadvantages

  • More expensive than many other manual grinders on the market.
  • Grinding is time-consuming compared to an electric.
  • Not the easiest grinder to clean.

If it wasn't for the coffee, I'd have no identifiable personality whatsover.

      You will never get good coffee using a blade grinder since the grind size is too inconsistent and it generates too much heat so dries out the coffee. It's burrs or nothing for me.
