The Benefits of Using a Coffee Grinder
Experts agree that purchasing and using coffee grinders is one of the best coffeee grinder upgrades you can make to your morning routine. The more expensive models come with burr coffe grinders, which are a pair of grooved surfaces that can be adjusted to provide a more consistent grind.
These grinders are better than blade grinders as they stop oxidation, and ensure that your ground is even in size.
Conical Burrs
Burr grinders are a stronger type of coffee grinder which makes use of angled opposing cutting surfaces to reduce whole beans into smaller particles. They produce less fines (also called dust) than blade coffee grinders and you can alter the size of the particles by adjusting the distance between the burrs.
There are two kinds of burrs, flat and conical. The differences between flat and conical burrs are subtle, but significant. Each has distinct strengths.
Blade grinders have sharp blade-shaped teeth that crush the coffee with each passing 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. If they are set correctly, they produce a very uniform grinding, with less pieces and no heating.
A high-quality burr grinder will have a lubricated mechanism to reduce friction and extend the life of the blades. They should also be easily cleaned to reduce the accumulation of coffee residue. There are hand-powered burr grinders. However, commercial flat burr grinding machines are almost always powered by electricity because they require more energy than can be supplied by the human hands by themselves.
Within each category of burr shape there is a variations between different models and brands of grinders. These differences aren't due to the shape or geometry of the burrs but the way their patterns relate to particle size distribution. For example, some conical burr grinders, such as the Niche Zero have very low retention, whereas other flat burr grinders such as the Iberital MC2 have a high retention.
Some coffee lovers believe that certain burr styles produce specific flavor profiles in the bean or roast. But this is a subject that is largely anecdotal and not well established scientifically.
Flat Burrs
Flat burrs are circular plates with sharp ridges facing each one. They crush coffee between them. These are the most commonly used burrs that are used in both home and commercial grinders. They are also the most common burrs that are employed in manual grinders.
Flat burrs have a harder time maintaining a uniform distribution of grind sizes than conical ones because their cutting edges are angled and can leave behind grit or fines. This can result in poor extraction and bitter flavors. However, this shouldn't be a deal breaker for some, especially since new innovations in burr design allow for the same clarity associated with flat burrs but with a more consistent grind size distribution.
When it comes to choosing the best conical or flat burr mill grinder grinder, the choice will largely come down to your specific grinding needs and unique tastes. For example a barista who grinds large quantities for several cups throughout the day could be more likely to opt for a flat burr grinder since it produces less fines and reduces the time to oxidize, making it easier to store and use again.
Another consideration is the quantity of heat a grinder produces during its operation. This is a significant aspect because it can impact the flavor and quality of your cup of joe. The more friction that a grinder produces and the more heat it creates. This can alter the flavor of your beans and result in over-extraction. Fortunately, flat-burr grinders produce less heat than their conical counterparts, which means they can provide you with the best taste overall.
If you're in the market for coffee grinders with flat burrs, there's a wide range of options from reputable brands like Baratza and Eureka. For instance the Fellow Ode Gen 2 is an option that is popular because it's easy to calibrate and provides a high degree of precision. It also has a low noise level and is suitable for espresso grinding. It does not 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
The process of grinding, no matter what kind of grinder you choose to use, produces a range of shapes and sizes. It is hard to quantify this in a meaningful way, unless you have expensive equipment like laser particle diffraction.
Instead of providing an exact measurement of the size of the particle the majority of coffee grinders have adjustable dials that let the user choose between a range of grind sizes. The dials are typically marked by a series of dots or numbers that indicate smaller and larger sizes. The numbers are usually followed by arrows that indicate the direction in which the dial should be moved to make the grind more fine or more coarse.
Many grinders also come with visual representations to assist you in choosing the correct setting. They include dots or a series, or a stepped adjustment system. While these visual representations can be helpful, they are only a general guide and will require you to experiment with the different settings.
For instance, a dot or number that appears close together indicate that the burrs are set very delicate, whereas a dot or number that appears further away indicates they're set extremely coarse. When deciding on a grinder's setting be sure to be aware that even minor adjustments can make a massive difference.
Dialing in a grinder is finding the best grind setting for the coffee and the brewing method. The best grind setting will allow for the most full-bodied and balanced flavor to be expressed while remaining within acceptable limits of extraction. This is a constant goal since even minor deviations from the "sweet spot" can result in over- or under-extracted coffee.
For espresso, a fine grind is optimal because it maximizes the amount water that comes in contact with the grounds during the limited time it takes for extraction. A setting that is similar in consistency to powdered sugar works for all brewing methods, including pour-over, French press, Aeropress and Turkish coffee.
Easy Cleaning
As coffee grinds go through your grinder, oils and old grounds get stuck inside the nooks and crannies of the machine. The oils that accumulate eventually go rancid, and begin to alter the taste of your espresso. Regular cleaning helps prevent the build-up of coffee oil and can keep your grinder running at its peak.
To clean your grinder, begin by disconnecting the plug and then removing the hopper and grounds bin. Then, you can remove the burrs. Be careful not to damage the burrs' sharp edges. They are able to scratch or scratch the interior of your grinder. Use a grinder cleaning brush to clean any coffee machine and grinder that has accumulated on the burrs. Instead you can make use of a soft brush or toothpick to gently remove ground beans from burrs. Once you have removed the burrs, and any other coffee particles from the machine, wipe it down with a clean dry cloth.
Whether you're using a burr grinder or a blade grinder cleaning your grinder on a regular basis is crucial. The flavor and aroma of coffee beans disappear once the beans are ground. The best espresso is made with freshly ground coffee. A grind that is too fine can result in bitterness and excessive extraction, while a grind that is too coarse could result in under-extraction and a weak flavor.
Cleaning your grinder on a regular basis will ensure that it is in good working order and produces quality grounds for your morning cup of coffee. Remaining oily residues and allowing old ground coffee to build up in the nooks and crevices could result in clogged blades and poorer-quality Ethically Sourced coffee grinders. The stale coffee you leave to accumulate on the burrs could also alter the taste of your coffee maker with grinder.
There are many ways to clean a grinder but one of the easiest is by using a coffee grinder cleaning tablet (such as Urnex Grindz). These tablets are made of edible grains that bind to and take away coffee oils. They're a great alternative to washing your burrs in 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 on your keyboard.
