The Benefits of Using a Coffee Grinder

Experts agree that purchasing and using a coffee grinder is among the best enhancements you can add to your morning routine. The higher-end models feature burr grinders, which are comprised of grooved surfaces which can be adjusted to ensure an even and consistent grind.

These grinders are superior to blade grinders since they prevent oxidation, and ensure that your ground is even in size.

Conical Burrs

Burr grinders are a stronger type of coffee grinder that uses an angled cutting surface to break beans down into smaller pieces. They produce less fines (also known as dust) than blade industrial coffee grinder grinders and you can control the size of the particles by changing the distance between the burrs.

There are two types of burrs - flat and conical. The differences between these two kinds of burrs is subtle but important, and each has its own distinct strengths.

Burr grinders crush beans using a pair disc-shaped burrs. Blade grinders make use of sharp, blade-shaped blades. The two burrs can be moved closer or farther apart to achieve the desired grind size. When they are properly set they produce a consistent grind with fewer tiny fragments and no heat.

A good quality burr grinder will have a lubricated mechanism to reduce friction and prolong the life of the blades. They must be easy to clean to prevent the build-up of coffee residue. There are some hand-powered burr grinders. However commercial flat burr grinders are usually powered by electricity because they require more energy than can be supplied by the human hands alone.

Within each category of burr shape, there may be further variation between different brands and models of grinders. These differences are not due to the shape of the burrs but rather to the pattern of their geometry and how that is related to the distribution of particle sizes. Some conical burr grinding machines, such as the Niche Zero, have very low retention. Other flat burr grinding equipment, such as the Iberital MC2 have a high retention.

Some coffee lovers claim that certain burr styles bring out specific flavours in the roast or bean. This is an area in which the evidence is mostly based on anecdotes, and not scientifically proven.

Flat Burrs

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

Flat burrs have a difficult time maintaining an even distribution of sizes of grind than conical ones due to the fact that their cutting edges are angled and can leave behind grit or fines. This can lead to bitter taste and poor extraction. However, this shouldn't be an issue for everyone particular people, especially as new developments in burr geometry can provide the same clarity associated with flat burrs but with more uniform the distribution of grind size.

The decision between a conical or flat burr grinder will depend on your specific grinding requirements and tastes. For example the barista who grinds a lot for several 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 can reduce the time of oxidation which makes it easier to store and reuse.

The amount of heat that the burr mill produces operating is a different factor to consider. This is an important aspect because it can impact the taste and quality of your coffee. The more friction grinders create and the more heat it generates. This could alter the flavor of your beans or result in over-extraction. Flat burr grinders generate less heat than conical grinders, and can give you a cleaner overall taste.

If you're looking for a coffee coffeee grinder that has flat burrs, there's a wide range of options available from reputable brands like Baratza and Eureka. For example the Fellow Ode Gen 2 is an extremely popular choice due to its easy to calibrate and has a the highest level of precision. It also has a very low noise level and is suited for espresso grinding. It doesn't produce the same quantity of fines as Baratza and other premium models and it is difficult to get a medium-fine grind for espresso.

Variable Grind Settings

The process of grinding, no matter what type of grinder you use, produces a range of particle sizes and shapes. It is difficult to measure 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 offer a precise measurement, but instead come with dials for setting adjustment that allow users to choose among a variety of sizes of grind. The dials are usually marked with a sequence of numbers or dots that represent smaller and larger sizes. The numbers are often accompanied by arrows to indicate the direction in which the dial should be moved to make the grind finer or more coarse.

In addition to the numerical system, many grinders have other visual representations to help with choosing the right setting, for instance dots in a series or a stepped adjustment mechanism. These visual representations are helpful, but they are only general guidelines and you will need to test different settings.

For instance, a dot or number that looks close together will indicate that the burrs are set extremely fine, while an asterisk or number that appears farther apart indicates that they are extremely coarse. When choosing a grinder setting, you should be aware that even tiny adjustments can make a massive difference.

Dialing in a grinder involves finding the ideal grind setting for the coffee and brewing method. The best grind setting allows the brew to have the most full and balanced flavor that is possible while staying within an acceptable range for extraction limitations. This is a constant pursuit, since even slight variations could result in coffee that is over- or under-extracted.

A finer grind is ideal for espresso as it maximizes how much water will be in contact with the ground during the brief time needed to extract. Pour-over, French Press, Aeropress, and Turkish Coffee all benefit from a setting that is similar to powdered white sugar.

Easy Cleaning

When coffee grinds move through your grinder, old grounds and oils are accumulated in the crevices. Eventually, these accumulations of oils turn rancid and start to impact the taste of your coffee grinders types. Regular cleaning can help prevent the buildup of stale oil in your grinder and keep it running at its peak.

To clean your grinder, start by unplugging and removing the hopper and grounds bin. Then, remove the burrs. Be careful not to scratch the burrs' sharp edges, which could easily scratch or scratch the interior of your grinder. If you have a grinder cleaner brush, apply this on the burrs in order to remove any coffee that is stuck. If you don't own a grinder cleaner brush then use a toothpick, or a soft brush to gently remove ground coffee from the burrs. Once 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 use a burr or blade grinder. Coffee beans lose their flavor and aromatic properties when they are ground. The best cup of coffee is made from freshly ground batches. A grind that is too fine could cause bitterness and over-extraction while too coarse a grind can lead to under extraction and the flavor is weak.

Cleaning your grinder frequently is the only way to make sure that it stays in optimal shape and produces quality grounds for your morning coffee. The lingering of oil residues and old ground coffee to accumulate in the nooks and crannies can result in clogged blades and poorer-quality coffee. The stale coffee you leave to collect on the burrs can also impact the taste of your coffee.

There are many ways to clean a grinder, however, one of the easiest is by using a coffee grinder cleaning tablet (such as Urnex Grindz). These tablets are made of edible grains that bond with and eliminate coffee oils. They're an excellent alternative to washing your burrs with 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 a keyboard air blower.
