15 Up-And-Coming Trends About Coffee Grinders

The Benefits of Using a Coffee Grinder

Experts believe that adding a coffee grinder to your daily routine is a great way to improve. The more expensive models come with burr grinders--a pair of grooved surfaces that can be adjusted to create an even and consistent grind.

In contrast to a blade grinder these kinds of grinders coffee beans stop oxidation and ensure your grounds are uniform in size.

Conical Burrs

Burr grinders have greater capacity and use opposing angles cutting surfaces that grind whole beans into small pieces. They produce fewer fines (also called dust) than blade coffee grinders and you can regulate the size of particles by adjusting the distance between the burrs.

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

Blade grinders feature sharp blade-shaped teeth, which crush the coffee beans grinder machine with each passing, burr grinders use disc-shaped burrs to grind the beans. The two burrs can be moved closer or further apart to determine the desired size of grind between coarse and fine. If they are set properly, they create a very consistent grind with fewer tiny fragments and without heat.

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

Within each type of burr there could be additional variations between different brands and models of grinders. These variations aren't due to the shape or the geometry of the burrs, but to the way their patterns relate to the distribution of particle size. Some conical burr grinding machines like the Niche Zero, have very low retention. Other flat burr grinding machines, like the Iberital MC2, have high retention.

Certain coffee enthusiasts claim that certain burr styles bring out specific flavours in the roast or bean. This is an area in which the evidence is mostly anecdotal and not well-established scientifically.

Flat Burrs

Flat burrs are plates with sharp ridges that face one opposite and crush the coffee beans between them. They're among the most popular burrs that are found in grinders for home and commercial use and are typically the primary kind used in manual coffe grinders.

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

When it comes to choosing a conical or flat burr grinder, the decision will be largely based on your specific grinding requirements and individual preferences. A barista who grinds several cups of coffee every day might choose a flat burr mill because it produces less fines and decreases the oxidation process, making it easier to store.

Another factor to consider is the amount of heat a burr grinder produces during its operation. This is an important factor because it can affect the taste and quality of your coffee. The more friction that a grinder produces and the more it's likely to heat up, which can change the flavor profile of your beans and lead to excessive extraction. Luckily, flat burr grinders generate less heat than their conical counterparts, which means they'll give you a cleaner taste overall.

If you're in the market for a coffee grinder with flat burrs, there's a wide range of options available from reputable 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 a high degree 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 can be difficult to achieve a medium-coarse grind for espresso.

Variable Grind Settings

The process of grinding, no matter what type of grinder you are using, produces a range of shapes and sizes. Measuring this in any meaningful way is difficult, unless you use very expensive equipment such as laser particle diffraction analysis.

Most coffee grinders do not provide a precise measurement, but instead use adjustable dials that permit users to choose between various grind sizes. Dials are marked with numbers or dots to indicate larger and smaller 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 numbering system, many grinders also have other visual representations that can help with choosing the right setting, like dots in a series or an adjustable step mechanism. These indications are helpful but they are not exact guidelines, and you'll have to play around with different settings.

For example for instance, a dot that appears close together could suggest that the grinders are set extremely fine, whereas a dot or number that appears farther apart indicates that they are very coarse. When choosing a grinder setting it is important to be aware that even tiny adjustments can make a huge difference.

Dialing in a grinder is finding the best grind setting for the coffee and the method of brewing. The best grind setting will allow for the most balanced and full-bodied flavor to be expressed while remaining within acceptable limits of extraction. This is a constant pursuit because even minor variations could result in coffee that has been over- or underextracted.

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

Easy Cleaning

When coffee grinds move through your grinder, old grounds and oils are accumulated in the nooks. Eventually, these accumulations of oils turn rancid and start to impact the taste of your coffee. Regular cleaning will prevent the accumulation of stale oil in your grinder and keep it functioning at its peak.

To clean your grinder, start by unplugging it, then removing the hopper. Then, you can remove the burrs. Be careful not to damage the sharp burrs that can easily scratch or grate inner surfaces. If you own a smart grinder pro cleaner brush, you can use this on the burrs to get rid of any electric coffee grinder residue. Instead you can employ a toothpick or soft brush to gently remove ground beans from burrs. Once you've removed the burrs as well as any other coffee particles, wipe the entire machine with a dry cloth.

Whether you're using a burr grinder or a blade, cleaning your grinder regularly is important. The aroma and taste of coffee beans is lost once the beans are ground. The best espresso is made from freshly ground coffee. Grinds that are too fine can cause bitterness and excessive extraction, while grinds that are too coarse could result in under-extraction, and a weak or thin flavor.

Cleaning your grinder frequently is the only way to ensure it stays in optimal condition and continues to produce quality grounds for your morning brew. The lingering of oil residues and old ground coffee to build up in the nooks and crevices can result in obstructions to the blades and poorer quality coffee. The stale coffee you leave to collect on the burrs can also alter the flavor 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 from edible grains that bond with and eliminate coffee oils. These tablets are an excellent alternative to soak your burrs in a solution water, which could harm or dull them. You can also clean your burrs by using brushes or blowing them off with compressed air or a keyboard air blower.
