Why Nobody Cares About Coffee Grinders

The Benefits of Using a Coffee Grinder

Experts agree that purchasing and using a coffee grinder is one of the best improvements you can make to your daily routine. The more expensive models have burr grinders, which are a pair of grooved surfaces that can be adjusted for an even and consistent grind.

Unlike a blade grinder, these kinds of grinders stop the oxidation of your ground and ensure that they are even in size.

Conical Burrs

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

There are two kinds of burrs, conical and flat. The differences between conical and flat burrs are not obvious but significant. Each has distinct strengths.

While blade grinders have sharp, blade-shaped teeth that bludgeon the coffee with each passing Burr grinders employ a pair of disc shaped burrs to grind beans. The two burrs can be moved closer or further apart to establish the desired grind size from coarse to fine. When properly set they result in a regular grinding process with fewer pieces and no heating.

A good quality burr grinder should feature a lubricated mechanism in order to reduce friction and prolong the life of the blades. They should also be cleaned easily, reducing the accumulation of coffee residue. While there are some hand powered burr coffe grinders, commercial flat burr grinders are almost always powered by electricity as they require more power than can be generated by a human hand alone.

Within each type of burr, there may be further variation between different brands and models of grinders. These differences aren't due to the shape or geometry of the burrs but how their pattern is related to the distribution of particle size. For example, 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 enthusiasts believe that different burrs are more effective in bringing out certain flavor notes in the roast and bean. This is an area in which the evidence is mostly anecdotal, and not scientifically proven.

Flat Burrs

Flat burrs consist of circular plates with sharp ridges that face each one. They crush the coffee between them. They're the most commonly used burrs used in grinders for home and commercial use and are the most common type used in manual grinders.

Flat burrs may have a difficult time maintaining the same distribution of grind sizes than conical ones, as their cutting edges are angled and can leave behind fines or grit. This can lead to bitter tastes and poor extraction. This isn't a major issue for everyone, since new innovations in burr geometries can provide the same consistency in grind size distribution as flat burrs.

When it comes to deciding between the best grinder machine conical or flat burr grinder, the decision will be largely based on your specific grinding requirements and particular preferences. For instance, a barista who grinds a lot for several cups throughout the day may prefer to go for a flat-burr grinder due to the fact that it produces fewer fines and reduces oxidation time, making it easier to store and reuse.

Another thing to consider is the quantity of heat a grinder produces during its operation. This is important because it can affect the taste and quality of your cup of coffee. The more friction a grinder creates and the more it's likely to get hot, which could change the flavor profile of your beans and cause excessive extraction. Flat burr grinders produce less heat than conical grinders. This can give you a cleaner overall taste.

There are many options for a coffee grinder that features flat burrs from well-known manufacturers like Baratza and Eureka. For instance the Fellow Ode Gen 2 is an extremely popular choice due to its easy to calibrate and provides the highest level of precision. It is also very quiet and is suitable for espresso. It doesn't produce the same amount of fines as Baratza and other models of premium and it is difficult to achieve a medium-coarse grind for espresso.

Variable Grind Settings

No matter what type you grind the material, the process creates a variety of particle sizes and shapes. The measurement of this in a meaningful manner is a challenge, unless you use very expensive equipment like laser particle diffraction analysis.

The majority of coffee grinders don't provide a precise measurement, but instead have a set adjustment dials which permit users to choose among a variety of grind sizes. Dials are marked with numbers or dots to indicate larger and smaller sizes. The numbers are usually followed by arrows that indicate the direction in which the dial should be moved to make the grind smoother or coarser.

Many grinders also come with visual representations to aid in selecting the best setting. These include dots or a series or a stepped adjustment system. While these indications are helpful, they are only a general guide and require you to test the various settings.

If the dots or numbers are close the odds are that they are well set. If they are farther apart then they are very coarsely set. When choosing a grinder setting it is important to keep in mind that even tiny adjustments can make a huge difference.

Dialing in a grinder is finding the best grind setting for the coffee and the brewing method. The ideal grind setting permits the brew to express the most full and balanced flavor, while remaining within a reasonable range for extraction limitations. This is a constant goal since even minor deviations from the sweet spot can result in under- or over-extracted coffee.

A finer grind is perfect for espresso as it maximizes the amount of water in contact with the ground during the short time required for extraction. Pour-over, French Press, Aeropress, and Turkish Coffee all benefit from a setting that is similar to powdered white sugar.

Easy Cleaning

As coffee grinds pass through your grinder, oils and old grounds get stuck inside the nooks and crannies in the machine. In time, these oil build-up becomes rancid and begin to affect the taste of your coffee. Regular cleaning will prevent the accumulation of stale oil in your smart grinder pro and keep it working at its best.

To clean your grinder, begin by unplugging and removing the grounds bin and hopper. Then, you can remove the burrs. Be careful not to harm the burrs' sharp edges. They can easily scratch or scrape the inner surfaces of your grinder. Use a grinder cleaning brush to remove any coffee residue that is stuck to the burrs. If you don't own a grinder cleaner brush you can use a toothpick or soft brush to gently remove the ground coffee from the burrs. Once you've removed the burrs, as well as any other coffee particles, clean the entire machine clean using a dry, clean cloth.

Cleaning your grinder on a regular basis is crucial, regardless of whether you use a burr or blade grinder. The flavor and aroma of coffee beans disappear once the beans are ground. The most delicious cup of espresso is made of freshly ground coffee. Too fine a grind can cause bitterness and over-extraction, and a grind that is too coarse can result in the coffee being under-extracted and having a weak flavor.

Regularly cleaning your grinder will ensure that it is in top condition and produces quality grounds for your morning coffee. Oil residues and old coffee grounds can cause the blades to become blocked and create poor-quality coffee. The stale coffee you leave to build up on the burrs may also affect the flavor of your small coffee grinder.

There are many ways to clean a grinder however, one of the easiest is to use a coffee grinder cleaning tablet (such as Urnex Grindz). These tablets are made of edible grains that bond to and remove coffee oil. These tablets are a great alternative to soaking your burrs in a solution of water, which can damage or dull them. You can also clean your burrs with a brush or by blowing them out using compressed air or an air blower for your keyboard.
