The Benefits of Using a Coffee Grinder

Experts agree that adding a coffee maker to your daily routine is a fantastic way to upgrade. The higher-end models feature burr grinders which consist of a pair of grooved surfaces which can be adjusted to ensure a more consistent grind.

Unlike a blade grinder, these types of grinders ward off oxidation and ensure your grounds are even in size.

Conical Burrs

Burr grinders are a more powerful type of coffee grinder that makes use of angled opposing cutting surfaces to reduce whole beans into smaller particles. They create fewer fines (also known as dust) than blade grinders and they let you control exactly what size of particle is produced by adjusting the distance between the burrs.

There are electric coffee grinder of burrs that are conical and flat. The differences between conical and flat burrs aren't obvious, but significant. Each has its own unique strengths.

Burr grinders crush beans with a pair of disc-shaped burrs, while blade grinders make use of sharp, blade-shaped blades. The two burrs are moved closer or farther apart to create the size of the grind you want. If they are set correctly, they produce a very uniform grinding, with less fragments and no heating.

A good quality burr grinder should feature a lubricated mechanism in order to reduce friction and extend the life of the blades. They should be easy to clean, preventing the build-up of coffee residue. While there are some hand-powered burr grinders, commercial flat burr grinders are almost always powered by electricity since they require more power than can be provided by the human hand by itself.

There are variations within each category of burr shapes between different brands and models. These differences aren't due to the shape or the geometry of the burrs, but to how their pattern is related to the distribution of particle size. Certain conical burr grinders, such as the Niche Zero, have very low retention. Other flat burr grinding equipment, like the Iberital MC2, have high retention.

Some coffee lovers claim that certain burr styles produce specific flavors in the bean or roast. However, this is an area that is largely based on speculation and is not well-established scientifically.

Flat Burrs

Flat burrs are circular plates with sharp ridges which face each opposite and crush the coffee beans between them. They're among the most popular burrs used in grinders for home and commercial use and are typically the primary type used in manual grinders.

In comparison to conical burrs flat ones may be more difficult to maintain the same size of grind due to the angled shape of their cutting edges may leave behind some grit and fines. This can result in poor extraction and bitter flavors. However, this shouldn't be an issue for all people, particularly since recent advancements in burr geometry can provide the same clarity that is found in flat burrs, but with more uniform grind size distribution.

When it comes down to selecting the best conical or flat burr grinder, the choice will largely come down to your specific grinding requirements and particular preferences. A barista who grinds multiple cups of coffee throughout the day may choose the flat burr mill as it produces less fines and decreases the oxidation process, making it easier to store.

Another consideration is the quantity of heat a grinder generates during operation. This is a crucial aspect because it can impact the flavor and quality of your coffee. The more friction that a grinder produces, the more it will get hot, which could alter the flavor profile of the beans and result in over-extraction. Fortunately, flat burr grinders generate less heat than their conical counterparts, which means they will provide you with the best taste overall.

If you're looking for coffee grinders with flat burrs, there's a wide range of options from reputable brands such as Baratza and Eureka. For example, the Fellow Ode Gen 2 is an option that is popular because it's easy to calibrate and offers a high degree of precision. It also has a very low noise level and is ideal for espresso grinding. It doesn't produce the same quantity of fines as Baratza and other premium models, and it can be difficult to achieve a medium-coarse grind when grinding espresso.

Variable Grind Settings

The process of grinding regardless of the type of grinder you are using creates a variety of particle sizes and shapes. Measuring this in any meaningful way is difficult, except for equipment like laser particle Diffraction Analysis.

The majority of coffee grinders don't offer a precise measurement, but instead use a set adjustment dials which allow the user to select between a variety of grind sizes. Dials are marked by 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 finer or more coarse.

In addition to the numbering system, many grinders also have other visual representations to assist in deciding on the best setting, like dots in a series or an adjustable step mechanism. While these indicators can be helpful however, they are only a general guideline and will require you to experiment with the different settings.


If the dots or numbers are close and are close together, then they are finely set, and if they are farther apart then they are very coarsely set. When deciding on a grinder's setting be sure to keep in mind that even tiny adjustments can make a huge difference.

Dialing in a grinder is finding the ideal grind setting for the coffee and the method of brewing. The ideal grind setting allows the brew to be able to produce the fullest and balanced flavor that is possible, while remaining within an acceptable range for extraction limitations. This is a constant goal since even minor deviations from the'sweet spot' could result in over- or under-extracted coffee.

A very fine grind is perfect for espresso because it increases the amount of water that is in contact with the ground during the short time required to extract. A setting that is similar to powdered sugar works for all methods of brewing, such as pour-over, French press, Aeropress and Turkish coffee.

Easy Cleaning

As coffee grinds go through your grinder old grounds and oils accumulate in the nooks. The oils that accumulate eventually go rancid and start to affect the taste of your espresso. Regular cleaning can help prevent the build-up of coffee oils and keeps your grinder working at its best.

To clean your grinder, begin by unplugging and removing the hopper and grounds bin. Then, take the burrs off. Be careful not to scratch the sharp burrs that can easily scratch or grate the inner surfaces. If you have a grinder cleaner brush, use it on the burrs to remove any coffee that is stuck. Instead you can employ a toothpick or soft brush 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 regularly is essential, regardless of regardless of whether you use the blade or burr. Coffee beans lose their flavor and aroma when they're ground. The best cup of coffee is made from freshly ground beans. A grind that is too fine could cause bitterness and over-extraction, and a grind that is too coarse could result in the coffee being under-extracted and having a weak flavor.

Cleaning your grinder on a regular basis will ensure it remains in good working order and produces quality grounds to make your morning coffee. Oil residues and old coffee grounds can cause the blades to get clogged and create poor-quality coffee. The flavor of coffee can be affected by allowing stale coffee to build up on the burrs.

There are a variety of ways to clean your grinder, but the easiest is to make use of the coffee grinder cleaner tablet (such as Urnex Grindz). These tablets are made of edible grains that bond with and eliminate coffee oils. These tablets are an excellent alternative to soaking your burrs in a solution water, which could damage or dull them. You can also clean your burrs by using brushes or blowing them off with compressed air or an air blower for your keyboard.
