How Does A Burr Coffee Grinder Work? [Types, Pros, Cons]

Do you love the taste of a fresh cup of coffee in the morning? If so, you need to invest in a burr coffee grinder to get the precise grind for the cup of joe, and grinding your own coffee bean is really worth it.

If you want to preserve the coffee aroma, you should definitely grind your beans just before brewing, and you couldn’t ask for more than a burr coffee grinder.

Here, I will discuss how a burr coffee grinder works, its types, and how to maintain them. I’ll also take a look at some of the best burr grinders on the market right now and see what makes them so unique. So let’s get started!

What Is A Burr Coffee Grinder?

A burr grinder is a coffee bean grinder that uses two abrasive surfaces called burrs to grind the beans. The distance between the burrs determines how finely or coarsely the coffee is ground.

There are two types of burr grinders:

  • Flat Burr Grinder
  • Conical Burr Grinder

How Does A Burr Coffee Grinder Work?

The coffee beans are placed in the hoppers at the top of the grinder. Between two burrs for both flat & conical grinders, one burr remains fixed while the other rotates by a motor. The beans are sucked between the two burrs, where they are crushed and ground into a consistent size throughout the batch.

In other words, burr grinders accomplish their task of reducing the size of whole coffee beans by pulverizing between two different sets of burrs. This results in coffee having a particle size that is reasonably uniform throughout.

Burrs are made of different materials, such as steel or ceramic.

Ceramic burrs are usually found in manual grinders and stay sharper longer than steel burrs. This implies that you won’t have to replace your grinder very often. They also tend to produce less mess than other types of grinders, however, might be far more challenging to clean and more expensive.

Steel Burrs are found in both manual and electric grinders. They wear down faster than ceramic burrs but are also less expensive to replace.

The type of material used for the burrs will affect how long the grinder will last, how well it grinds the coffee, and how much noise it makes.

The majority of burr grinders provide many grind settings. Grind adjustments are generally two types: Stepped and Stepless adjustments

Stepped includes pre-determined parameters for you to pick from, while Stepless enables nearly endless alterations depending on your preference.

The finer the grind, the more surface area of the bean is exposed to hot water, which will result in a more intense cup of coffee. The coarser the grind, the less surface area of the bean is exposed to hot water, which will result in a less intense cup of coffee.

The grind setting you choose will depend on the brewing method. For example, if you use a French press, you will want to use a coarser grind. If you are using an espresso machine, you will want to use a finer grind.

Flat Burr Grinders Vs. Conical Burr Grinders Comparison

Both flat and conical burr grinders are available, as I said before. But how do they differ in operation, which one to choose, and how do they affect the consistency & precision of the grind, let’s know a bit more in detail.

Flat Burr Grinders: Flat Burr Coffee Grinders have two parallel rings and are the same size. The ring facing the opposite ring has angled teeth. Between these two burrs, the beans are ground.

Conical Burr Grinders: A cone-shaped burr lies within another cone-shaped burr in a conical burr grinder. Between the two cone-shaped burrs, the beans are ground. While both kinds of grinders are effective, flat burr grinders are often more costly.

Flat burrs are more costly and more consistent overall. They may also be loud, and if there isn’t enough ventilation, they can quickly become hot, depending on the model.

On the contrary, Conical burr grinders are less expensive, emit less heat, and produce a less uniform grind than flat burr grinders.

So, which one to choose? In order to buy a grinder, figure out what are the most essential features you need.

Do you own a specialty coffee business where attention to detail and accuracy are essential? What if you’re an early riser who requires a quiet coffee grinder for your home?

It’s essential to remember that burrs are only one factor among several when evaluating a grinder’s quality. Is the machine made of high-quality materials? Are they appropriate for the types of coffee you wish to make? Is there a dependable support system in place in case the product has to be repaired or replaced?

When you buy a coffee grinder, having the answers to these questions at your disposal will help you choose the most suitable one.

Burr grinder Vs Blade grinder

Blade grinders reduce whole coffee beans to fine powder by cutting them with a revolving blade. The problem with this is that the grind will be uneven and result in a bitter cup of coffee.

Burr grinders, on the other hand, work by crushing the beans between two burrs. This results in a more uniform grind, which is essential for making a great cup of coffee.

Another advantage of burr grinders is that they can be adjusted to grind the beans to a specific size. This is not possible with blade grinders.

Let’s see the pros and cons of a burr grinder over a blade grinder.

Pros of Burr Grinder: 

  • Coffee beans are ground more uniformly by burr grinders than by blade grinders. This means your coffee will taste better because all the coffee beans are extracted evenly.
  • Burr grinders also allow you to choose how fine or coarse you want your coffee to be ground with adjustable grind settings.
  • Burr grinders typically last longer than blade grinders because they are well-built, made of high-quality material, and don’t produce as much friction.
  • Using a burr grinder will ensure you won’t lose any flavor. The coffee grounds lose some of their taste due to the high temperature produced by blade grinders. 

Cons of Burr Grinder: 

  • The cost of a burr grinder may exceed that of a blade grinder.
  • It may be more difficult to clean a burr grinder than a blade grinder.
  • Burr grinders can be noisy, so if you are looking for a quiet grinder, you may want to consider a different type of grinder.

Blade grinders are suitable for beginners. Your coffee will taste marginally better if you use a blade grinder because at least you are not using pre-ground coffee. But using a burr grinder will completely revolutionize the experience in terms of flavor and potential.

Burrs are unrivaled when it comes to return on investment. If you can’t afford an expensive electric burr grinder, choose a manual coffee grinder on the more affordable side of the price spectrum.

Cleaning & Maintaining The Burr Grinder

To keep your burr grinder in good working condition, it is important to clean it on a regular basis. If you notice that your grinder is not grinding the beans as evenly as it used to, or if it is making more noise than usual, it is time to clean the burrs.

In short, you have to disassemble the burrs to clean them. However, in some grinder models, you can only remove the upper burr; check the manufacturer’s guidelines on how to dismantle the burr.

After that, you may use a brush or a toothpick to clean the teeth, the screws, and any other locations that are accessible. This will ensure that all of the grinds are removed. Cotton swabs can also access tight channels and crevices that are difficult to access with a stiff instrument.

Once the burrs are clean, wash other components, wipe down, and reassemble the unit. I have a detailed article on how to clean a burr coffee grinder. If you think you need more help, read that article.

Why Are Burr Grinders So Expensive?

The answer is simple: because they are worth it. A good burr grinder will last years and help you make better coffee. If you are serious about making great coffee at home, a burr grinder is an investment that will pay off in the long run.

In addition, it gives you the flexibility to swap between different brewing techniques. Suppose you used to have french press coffee; with a burr grinder having an adjustable setting, you can easily try Aeropress or Espresso coffee.

Read in detail here why burr grinders are so expensive, and why it is worth the money.
