The Benefits of Using a Coffee GrinderExperts believe that adding a coffee grinder to your morning routine is a great upgrade. The more expensive models have burr grinders that are made up of comprised of grooved surfaces that can be adjusted to provide a more consistent grind.As opposed to a blade-grinder, these types of grinders ward off oxidation and ensure your grounds are even in size.Conical BurrsBurr grinders are a more powerful type of coffee grinder which makes use of angles to break beans down into small particles. They produce less fines (also called dust) than blade coffee grinders. You can control the size of the particles by adjusting the distance between the burrs.There are two kinds of burrs, conical and flat. The differences between flat and conical burrs are not obvious but significant. Each has its own unique strengths.Burr grinders grind the beans using a pair disc-shaped burrs, while blade grinders employ sharp blades that are shaped like blades. The two burrs can be moved closer or further apart to determine the desired size of grind from coarse to fine. If they are set correctly, they produce a very regular grinding process with fewer fragments and without heating.A top-quality burr grinder must have a lubricated system to reduce friction and increase the life of the blades. They must be easy to clean, preventing the build-up of coffee residue. There are hand-powered burr grinders. However commercial flat burr grinding machines are typically powered by electricity as they require more energy than can be generated by human hand alone.There could be differences within the burr shapes of each category among different brands and models. These differences are not due to the shape of the burrs themselves but rather to the shape of their geometry and how it relates to the distribution of particle sizes. Certain conical burr grinders like the Niche Zero, have very low retention. Other flat burr grinding machines, like the Iberital MMC2 have high retention.Some coffee lovers believe that certain burr styles bring out specific flavours in the bean or roast. This is an area in which the evidence is mostly anecdotal and not well-established scientifically.Flat BurrsFlat burrs are plates with sharp ridges which face each to crush coffee beans between them. They’re the most commonly used burrs used in commercial and home grinders and are usually the primary kind used in manual grinders.As compared to conical ones, flat ones may have more trouble maintaining a uniform grind size distribution because of the angled design of their cutting edges can leave behind some fines and grit. This can result in poor extraction and bitter flavors. However, this isn’t necessarily an issue for everyone, especially since new innovations in burr geometry allow for the same clarity as flat burrs, albeit with a more consistent the distribution of grind size.The decision between a conical or flat burr grinder will be based on your unique grinding needs and tastes. For instance, a barista who grinds large quantities for multiple cups throughout the day may prefer to go for a flat-burr grinder since it produces less fines and reduces the time of oxidation which makes it easier to store and reuse.The amount of heat that a burr mill generates in operation is another factor to consider. This is a significant aspect because it can impact the flavor and quality of your cup of joe. The more friction grinders produce and the more heat it produces. This can change the taste of your beans or result in over-extraction. Fortunately, flat burr grinders generate less heat than their conical counterparts, which means they’ll give you a cleaner taste overall.There are many options for a coffee grinder that features flat burrs from reputable manufacturers such as Baratza and Eureka. For example, the Fellow Ode Gen 2 is a popular choice because it’s easy to calibrate and has a a high degree of precision. It also has a low noise level and is ideal for espresso grinding. It doesn’t produce the same amount of fines as Baratza and other premium models, and it can be difficult to achieve a medium-coarse grind when grinding espresso.Variable Grind SettingsNo matter what type grinding equipment you employ, the process produces different sizes of particles and shapes. It is hard to quantify this accurately without expensive equipment such as laser particle difffraction.Instead of offering an exact measurement of particle size, most coffee grinders have a set of adjustment dials that let the user choose between a range of sizes for grinding. Dials are marked by numbers or dots to indicate smaller and larger sizes. The numbers are sometimes followed by arrows which indicate the direction in which the dial is supposed to move to make the grind more coarse or finer.In addition to the numbering system, a lot of grinders have other visual representations that can help in selecting the correct setting, such as a series of dots or a stepped adjustment mechanism. These indications are helpful but they are not exact guidelines and you will need to experiment with different settings.For example for instance, a dot that looks close together will suggest that the grinders are set very fine, whereas a dot or number that appears farther apart means they are set very coarse. When selecting a grinder setting it is crucial to remember that even small adjustments can make an enormous difference and it’s important not to go too far out of the intended range when making your adjustments.The dialing-in process of grinding is the process of determining the best grind setting for a specific coffee and brewing method. The best grind setting allows the brew to express the most full and balanced flavor that is possible while staying within an acceptable range of extraction limits. This is a constant pursuit since even minor deviations from the sweet spot could result in over- or under-extracted coffee.A very fine grind is ideal for espresso because it increases the amount of water in contact with the ground in the brief time needed for extraction. A setting that is similar in consistency to powdered sugar is suitable for all brewing methods, including pour-over, French press, Aeropress and Turkish coffee.Easy CleaningAs coffee grinds pass through your grinder the grounds and oils are trapped in the crevices and corners of the machine. In time, these accumulations of oils turn rancid and can affect the taste of your coffee. Regular cleaning can prevent the buildup of stale oil in your coffee maker and keep it working at its best.To clean your grinder, begin by disconnecting the plug and then removing the grounds bin and hopper. Then, remove the burrs. Be careful not to damage the burrs’ sharp edges that could easily scratch or grate inner surfaces. Use a grinder cleaning brush to remove any coffee stuck on the burrs. If you don’t have a 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 and any other coffee particles, wipe the entire machine with a clean, dry cloth.If you’re using a burr grinder or a blade grinder, cleaning your grinder regularly is essential. The aroma and flavor of coffee beans disappear as soon as the beans are ground. The best espresso is made of freshly ground coffee. Too fine a grind can cause bitterness and over-extraction while too coarse a grind can result in under-extraction and a weak flavor.Cleaning coffee machine grinder on a regular basis will ensure that it is in good working order and continues to produce quality grounds for your morning cup of coffee. Leaving oil residues and old ground coffee to build up in the nooks and crannies can lead to obstructions to the blades and poorer quality coffee. Letting stale ground coffee collect on the burrs can also affect the taste of your coffee.There are many ways to clean your grinder, but the easiest is to make use of a coffee grinder cleaner tablet (such as Urnex Grindz). These tablets are made of edible grains that bond with and eliminate coffee oils. These tablets are an excellent alternative to soaking your burrs in a solution of water, which can damage or dull them. You can also use a brush to clean your burrs, or blow them off using compressed air or keyboard air blower.
