20 Myths About Coffee Grinders: Debunked
The Benefits of Using a Coffee Grinder

Experts agree that buying and using a coffee grinder is among the best improvements you can make to your daily routine. The more expensive models have burr grinders which consist of made up of two grooved surfaces which can be adjusted to ensure an even grind.

These grinders are better than blade grinders because they prevent the oxidation process, and ensure that your ground is uniform in size.

Conical Burrs

Burr grinders have a higher power and utilize opposing angled cutting surfaces that grind whole beans into tiny pieces. They produce less fines (also known as dust) than blade coffee grinders. Additionally, you can regulate the size of particles by altering the distance between the burrs.

There are two burr types: flat and conical. The differences between these two types of burrs are subtle but important and each one has its own unique strengths.

Blade grinders have sharp, blade-shaped teeth that bludgeon the coffee with each pass Burr grinders employ disc-shaped burrs to grind beans. The two burrs can be moved closer or further apart to establish the desired size of grind from coarse to fine. When they are set correctly they produce a consistent grind with fewer tiny pieces and no heat.

A high-quality burr grinder must have a lubricated mechanism to reduce friction and extend the life of the blades. coffee grinders sale must also be cleaned easily, reducing the accumulation of coffee residue. There are some hand-powered burr grinders. However commercial flat burr grinders are usually powered by electricity as they require more energy than can be generated by human hand by themselves.

Within each type of burr there could be additional variations between different models and brands of grinders. These variations aren't due to the shape or geometry of the burrs, but to how their pattern relates to the distribution of particle size. For instance, some conical burr grinders such as the Niche Zero have very low retention, while other flat burr grinders like the Iberital MC2 boast high retention.

Some coffee lovers claim that certain burr styles can bring out certain flavors in the bean or roast. This is an area where the evidence is mostly based on anecdotes, and not well-proven scientifically.

Flat Burrs

Flat burrs are plates with sharp ridges that face each opposite and crush the coffee beans between them. These are the most common burrs that are used in both commercial and home grinders. They are also the primary type of burrs used in manual grinders.

In comparison to conical burrs flat ones can have more trouble maintaining the same size of grind because of the angled design of their cutting edges can leave behind some grit and fines. This can lead to bitter flavors and poor extraction. This isn't a deal-breaker for everyone, as new innovations in burr geometries allow for the same grind size distribution as flat burrs.

When it comes to deciding between a flat or conical burr grinder, your choice will largely come down to your specific grinding needs and individual preferences. A barista who grinds several cups of coffee throughout the day may opt for a flat burr mill because it produces less fines and lowers the rate of oxidation, which makes it easier to store.

The amount of heat that a burr mill generates while in operation is another factor to be considered. This is important as it can affect the flavor and quality your cup of coffee. The more friction that grinders produce and the more heat it produces. This can alter the flavor of your beans and cause excessive extraction. Fortunately, flat-burr grinders produce less heat than their conical counterparts, so they'll give you the best taste overall.

If you're looking for a coffee grinder that has flat burrs, there's plenty of options available from reputable manufacturers like Baratza and Eureka. The Fellow Ode Gen 2 is popular because it's easy-to-calibrate and has a high level of precision. It is also very quiet and is suitable for espresso. It doesn't produce the same quantity of fines as Baratza and other top models and it is difficult to get a medium-fine grind for espresso.

Variable Grind Settings

No matter what type you use to grind the process, it produces a variety of particle sizes and shapes. The measurement of this in a meaningful manner is a challenge, unless you have expensive equipment like laser particle Diffraction Analysis.

Instead of providing an exact measurement of the size of the particle the majority of coffee grinders have an adjustment dial that let the user choose between a range of sizes for grinding. Dials are marked by numbers or dots to indicate larger and smaller sizes. The numbers are often followed by arrows that indicate the direction that the dial must be moved to make the grind smoother or more coarse.

In addition to the numerical system, many grinders have other visual representations to assist in selecting the correct setting, such as dots in a series or an adjustable step mechanism. While these indications are helpful, they are only a general guideline and will require you to test the different settings.


For example for instance, a dot that appears close together could indicate that the burrs are set very delicate, whereas the dot or number that appears farther apart indicates that they are extremely coarse. When choosing a grinder setting be sure to keep in mind that even small adjustments can make an enormous difference.

Dialing in a grinder requires finding the optimal grind setting for the coffee and the brewing method. The ideal grind setting permits the brew to have the fullest and balanced flavor possible, while remaining within an acceptable range for extraction limitations. This is a continuous pursuit because even minor variations could result in coffee that is over- or under-extracted.

For espresso, a very fine grind is optimal since it maximizes the amount of water that comes into contact with the ground during the time frame for extraction. A setting that is similar in consistency to powdered sugar works well for most brewing methods, including pour-over, French press, Aeropress and Turkish coffee.

Easy Cleaning

When coffee grinds move through your grinder the grounds and oils are trapped in the crevices and corners of the machine. Then, the oil build-up becomes rancid and can affect the taste of your coffee. Regular cleaning can to prevent the build-up of coffee oil and can keep your grinder working at its best.

To clean your grinder, start by unplugging it and taking out the hopper and the grounds bin. Next, take out the burrs. Be careful not to harm the sharp burrs, which are able to scratch or scratch the inside of your grinder. If you own a grinder cleaner brush, use this on the burrs to remove any coffee that is stuck. If you don't have a cleaner brush, use a toothpick or soft brush to gently remove the ground coffee from the burrs. After you have removed the burrs, and any other coffee particles from the machine, wipe it off with a clean dry cloth.

Whether you're using a blade grinder or a blade grinder, cleaning your grinder regularly is important. Coffee beans lose their flavor and aromatic properties when they're ground. The best cup of coffee comes from freshly ground beans. Grinds that are too fine lead to bitterness and over-extraction and bitterness, while those that are too coarse can result in under-extraction, and a sour or weak flavor.

Cleaning your grinder on a regular basis is the only way to ensure it remains in top shape and produces top-quality grounds for your morning coffee. Leaving oil residues and old ground coffee to accumulate in the nooks and crevices can result in obstructions to the blades and poorer quality coffee. The flavor of coffee can be affected by allowing coffee that is stale to build up on the burrs.

There are many ways to clean your grinder, but the easiest is to use a coffee grinder cleaner tablet (such as Urnex Grindz). These tablets are made up of edible grains that bind with and remove coffee oil. They're a great alternative to washing your burrs with water, which could damage or dull them. You can also clean your burrs using brushes or blowing them out using compressed air or a keyboard air blower.
