The Benefits of Using a Coffee Grinder

Experts agree that purchasing and using coffee grinders is one of the best enhancements you can add to your morning routine. The more expensive models have burr grinders that are made up of a pair of grooved surfaces that can be adjusted for an even grind.

These grinders are superior to blade grinders as they stop the oxidation process, and ensure that your ground is even in size.

Conical Burrs

Burr grinders are a powerful type of coffee grinder that uses angles to break beans down into smaller particles. They create fewer fines (also known as dust) than blade grinders and they allow you to decide exactly the size of particle is created by adjusting the gap between the burrs.

There are two burr types which are conical and flat. The differences between the two kinds of burrs are subtle but significant and each one has its own strengths.

Blade grinders have sharp blade-shaped teeth, which crush the coffee with each passing burr grinders utilize a pair of disc shaped burrs to grind the beans. The two burrs are moved closer or farther apart to create the size of the grind you want. When they are set properly they will produce a regular grinding process with fewer pieces and no heating.


A top quality burr grinder will feature a lubricated mechanism in order to reduce friction and extend the life of the blades. They are easy to clean to avoid the build-up of coffee residue. There are a few hand-powered burr grinders. However commercial flat burr grinders are typically powered by electricity since they require more energy than can be generated by human hand alone.

There are variations within the burr shapes of each category between different models and brands. These variations are not due to the shape of the burrs but rather the pattern of their geometry and how it relates to the distribution of particle sizes. Some conical burr grinding machines, such as the Niche Zero, have very low retention. Other flat burr grinding machines, such as the Iberital MC2, have high retention.

Certain coffee enthusiasts assert that different burr styles are better at bringing out certain flavors in the roast and bean. This is an area where the evidence is mostly based on anecdotes, and not well-proven scientifically.

Flat Burrs

Flat burrs are flat plates with sharp ridges which face each other and crush the coffee beans between them. They're the most commonly used burrs used in home and commercial grinders and are the most common kind used in manual grinders.

As compared to conical ones, flat burrs can be more difficult to maintain an even distribution of size because of the angled design of their cutting edges could leave behind grit and fines. This can lead to less extraction and bitter tastes. This shouldn't be a problem for everyone, because new developments in burr geometries can provide the same consistency in size distribution as flat burrs.

The choice between a conical or flat burr grinder will depend on your unique grinding needs and preferences. For example a barista who grinds large quantities for many cups throughout the day may be more likely to opt for a flat burr grinder due to the fact that it produces fewer fines and reduces oxidation time and make it easier to store and reuse.

best espresso coffee grinder of heat the burr mill produces operating is a different factor to be considered. This is important because it can affect the flavor and quality of your cup of coffee. The more friction that grinders create, the more heat it produces. This could alter the flavor of your beans or result in over-extraction. Fortunately, flat-burr grinders generate less heat than their conical counterparts, which means they'll give you a cleaner taste overall.

There are a variety of options for a coffee grinder that features flat burrs from reputable manufacturers such as Baratza and Eureka. For example, the Fellow Ode Gen 2 is an extremely popular choice due to its easy to calibrate and has a an extremely high level of precision. It also has a low noise level and is ideal for espresso grinding. However it doesn't create the same amount of fines as Baratza or other top models and can have difficulty producing a medium coarse grind for espresso.

Variable Grind Settings

The grinding process, no matter what type of grinder you are using results in a variety of shapes and sizes. It is difficult to measure this in a meaningful way is difficult, except for equipment like laser particle diffraction analysis.

The majority of coffee grinders don't provide a precise measurement, but instead come with adjustable dials that allow the user to select among a variety of grind sizes. Dials are marked with numbers or dots to indicate smaller and larger sizes. The numbers are often with arrows to indicate the direction in which the dial needs to be moved to make the grind smoother or more coarse.

A lot of grinders come with visual representations to assist you in choosing the correct setting. These can be a series or dots or a stepped adjustment system. While these indicators may be useful however, they are only a general guideline and will require you to test the various settings.

For instance, a dot or a number that appears close together could mean that the burrs are set extremely fine, while the dot or number that appears to be further apart indicates that they are extremely coarse. When deciding on a grinder's setting it is important to be aware that even small adjustments can make a huge difference.

The dialing in of grinding is the process of determining the most optimal grind setting for a particular coffee and brewing method. The optimal grind setting allows the most balanced and full-bodied flavor to be exhibited, while still remaining within acceptable limits of extraction. This is a constant pursuit because even minor variations can result in coffee that is over- or under-extracted.

A finer grind is perfect for espresso as it maximizes the amount of water in contact with the ground during the brief time needed to extract. A setting that is similar in consistency to powdered sugar works well for all methods of brewing, such as pour-over, French press, Aeropress and Turkish coffee.

Easy Cleaning

As coffee grinds pass through your grinder oils and old grounds are trapped in the nooks and crannies in the machine. Eventually, these accumulated oils go rancid and start to impact the taste of your coffee. Regular cleaning can prevent the build-up of coffee oil and can keep your grinder operating optimally.

To clean your grinder start by unplugging it, then remove the hopper. Then, take the burrs off. Be careful not to harm the burrs' sharp edges. They are able to scratch or scratch the interior of your grinder. Use a grinder cleaning brush to get rid of any coffee stuck on the burrs. Otherwise employ a soft brush or toothpick to gently lift the coffee grounds from the burrs. After you have removed the burrs, and any other coffee particles from the machine, clean it off with a clean dry cloth.

Cleaning your grinder on a regular basis is important, regardless of whether you're using a burr or blade grinder. Coffee beans lose their aroma and flavor as soon as they're ground, and the best cup of coffee is made from freshly ground batches. A grind that is too fine could result in bitterness and excessive extraction, while a grind that is too coarse could result in under-extraction and an unsavory flavor.

Cleaning your grinder frequently is the only way to ensure it is in good shape and produces quality grounds for your morning brew. Leaving oil residues and old ground coffee to accumulate in the nooks and crannies could result in obstructions to the blades and poorer quality coffee. The taste of coffee can be affected by allowing coffee that is stale to build up on the burrs.

There are many ways to clean a grinder, but one of the most effective is using a coffee grinder cleaning tablet (such as Urnex Grindz). These tablets are made of edible grains that bind with and take out coffee oil. They're an excellent alternative to washing your burrs in water, which could damage or dull them. You can also clean your burrs by using a brush or blowing them off with compressed air or an air blower for your keyboard.
