The Benefits of Using a Coffee Grinder

Experts agree that purchasing and using coffee grinders is among the most beneficial enhancements you can add to your morning routine. The pricier models feature burr grinders--a pair of grooved surfaces that can be adjusted to create a more consistent grind.

These grinders are better than blade grinders since they prevent burning, and also ensure that your ground is uniform in size.

Conical Burrs

Burr grinders are a more powerful type of coffee grinder which makes use of an angled cutting surface to reduce whole beans into small particles. They create fewer fines (also known as dust) than blade grinders and they allow you to control exactly what size of particle is created by adjusting the gap between the burrs.

There are two kinds of burrs, conical and flat. The differences between the two kinds of burrs is subtle but important, and each has its own unique strengths.

Blade grinders feature sharp, blade-shaped teeth that crush the coffee with each pass Burr grinders employ disc-shaped burrs to grind the beans. The two burrs can be moved closer together or further apart to determine the desired size of grind between coarse and fine. If they are set properly they will produce a homogeneous grind that has fewer tiny pieces and no heat.

A top-quality burr grinder must be lubricated to reduce friction and extend the lifespan of the blades. They are easy to clean, preventing the accumulation of coffee residue. There are some hand-powered burr grinders. However commercial flat burr grinders are typically powered by electricity because they require more energy than could be generated by human hand by themselves.

Within each type of burr, there may be further variations between different brands and models of grinders. These differences are not due to the shape of the burrs themselves but rather to the pattern of their geometry and how it relates to the distribution of particle sizes. 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.

Certain coffee enthusiasts claim that certain burr types can bring out certain flavors in the bean or roast. This is an area where the evidence is mostly anecdotal, and not well-established scientifically.

Flat Burrs

Flat burrs comprise of circular plates that have sharp ridges facing each other. They crush the coffee between them. They're the most commonly used burrs found in grinders for home and commercial use and are the most common type used in manual grinders.

As compared to conical ones, flat ones may have more trouble maintaining the same size of grind because the angled design of their cutting edges can leave behind some grit and fines. This can result in bitter tastes and poor extraction. However, this shouldn't be an issue for all, especially since new innovations in burr design allow for the same clarity that is found in flat burrs, but with a more consistent the distribution of grind size.

When it comes down to selecting the best conical or flat burr grinder, the decision will largely come down to your specific grinding needs and particular preferences. For instance the barista who grinds a lot for many cups throughout the day may be more likely to opt for a conical burr grinder since it produces less fines and may reduce the time to oxidize which makes it easier to store and reuse.

The amount of heat a burr mill generates in operation is another factor to consider. This is important as it can affect the flavor and quality your cup of coffee. The more friction that a grinder produces the more it will increase its temperature, which can alter the flavor of the beans and result in excessive extraction. Luckily, flat burr grinders produce less heat than their conical counterparts. As a result, they'll give you the best grinder machine taste overall.

There are many options for a grinder that has flat burrs from well-known manufacturers like Baratza and Eureka. For example, the Fellow Ode Gen 2 is an extremely popular choice due to its easy to calibrate and provides an extremely high level of precision. It also has a very low noise level and is ideal for espresso grinding. However, it doesn't produce as fine a grind as Baratza or other top models and may struggle to produce a medium coarse grind for espresso.

Variable Grind Settings

The grinding process regardless of the type of grinder you are using, produces a range of particle sizes and shapes. It is difficult to quantify this accurately, unless you have expensive equipment such as laser particle diffraction.

Rather than providing an exact measurement of particle size Most coffee grinders come with an adjustment dial that allow the user to choose from a range of grind sizes. Dials are marked by numbers or dots to indicate smaller and larger sizes. The numbers are often accompanied by arrows to indicate the direction that the dial must be moved to make the grind more fine or coarser.

In addition to the numbering system, a lot of grinders have other visual representations that can help with choosing the right setting, such as dots or an adjustable step mechanism. While these indicators are helpful but they are not a complete guide and will require you to play around with the different settings.

If the dots or numbers are close together, then they are very precisely set. If they are farther apart, then they are coarsely set. When deciding on a grinder's setting it is important to be aware that even minor adjustments can make an enormous difference.

The dialing-in process of a grinder is the process of finding the most optimal grind setting for the particular coffee machine with grinder and the method of brewing. The optimal grind setting allows the most balanced and full-bodied taste to be exhibited, while still remaining within the acceptable limits of extraction. This is a constant goal because even small deviations from the "sweet spot" can result in under- or over-extracted coffee.

For espresso, a fine grind is the best, as it maximizes the amount water that will come into contact with the grounds in the limited time it takes to extract. A setting that is similar in consistency to powdered sugar works well for all brewing methods, including pour-over, French press, Aeropress and Turkish coffee.

Easy Cleaning

When coffee grinds move through your grinder oils and old grounds get stuck inside the nooks and crannies in the machine. Eventually, these oil build-up becomes rancid and begin to affect the taste of your coffee. Regular cleaning can help prevent the accumulation of stale oil in your grinder and keep it functioning at its peak.

To clean your grinder, begin by unplugging it and taking out the grounds bin and hopper. Then, remove the burrs. Be careful not to damage the sharp burrs that can easily scratch or grate inner surfaces. If you own a grinder cleaner brush, use it on the burrs to get rid of any coffee residue. If you don't have a grinder cleaner brush, use a toothpick or soft brush to gently remove ground coffee from the burrs. After you've removed all burrs as well as any other coffee particles, wash the entire machine with a dry cloth.

Cleaning your grinder regularly is crucial, whether you use the blade or burr. Coffee beans lose their aroma and flavor as soon as they're ground, and the best burr grinder cup of coffee is made from a freshly ground batch. A grind that is too fine can cause bitterness and over-extraction while too coarse a grind can lead to under extraction and a weak flavor.

Cleaning your grinder regularly will ensure it remains in good working order and continues to produce quality grounds for your morning coffee. Remains of oil and old coffee maker with grinder grounds can cause the blades to get clogged and create poor-quality coffee. Letting stale ground coffee accumulate on the burrs could also affect the flavor of your coffee.

There are many ways to clean your grinder but the most effective is to use a coffee grinder cleaner tablet (such as Urnex Grindz). These tablets are made from edible grains that bind with and remove 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 employ a brush to scrub your burrs or blow them off using compressed air or keyboard air blower.
