The Benefits of Using a Coffee Grinder Experts agree that adding a coffee maker to your morning routine is a great upgrade The more expensive models have burr grinders which consist of comprised of grooved surfaces that can be adjusted for an even and consistent grind These grinders are better than blade grinders as they stop burning and also ensure that your ground is even in size Conical Burrs Burr grinders are a stronger type of coffee grinder that makes use of angled opposing cutting surfaces to reduce whole beans into smaller pieces They produce fewer fines also known as dust than blade coffee grinders Additionally you can alter the size of the particles by adjusting the distance between the burrs There are two types of burrs conical and flat The differences between these two types of burrs are subtle but important and each one has its own distinct strengths Blade grinders have sharp bladeshaped teeth that bludgeon the coffee with each passing Burr grinders employ a pair of disc shaped burrs to grind the beans The two burrs can be moved further or closer to create the desired grind size When properly set they result in a consistent grinding with fewer small pieces and no heating A highquality burr grinder will have a lubricated mechanism to reduce friction and extend the life of the blades They should also be able to be cleaned easily reducing the buildup of coffee residue Although there are hand powered burr grinders commercial flat burr grinders are almost always electrically powered as they require more power than can be generated by a human hand alone There may be variations within every category of burr shapes between different brands and models These variations arent due solely to the shape or the geometry of the burrs but to how their pattern relates to the distribution of particle size Certain conical burr grinders such as the Niche Zero have very low retention Other flat burr grinding equipment like the Iberital MC2 have high retention Certain coffee enthusiasts claim that certain burr styles bring out specific flavours in the bean or roast However this is a subject that is largely anecdotal and not scientifically proven Flat Burrs Flat burrs comprise of circular plates with sharp ridges facing each one They crush the coffee between them These are the most commonly used burrs found in home and commercial grinders They are also the most common type of burrs used in manual grinders Flat burrs can be more difficult to maintain a uniform distribution of sizes of the grind than conical ones due to the fact that their cutting edges are angled and can leave behind fines or grit This can result in bitter taste and poor extraction However this isnt necessarily an issue for everyone people particularly since recent advancements in burr geometry can provide the same clarity associated with flat burrs albeit with more uniform grind size distribution When it comes down to selecting a conical or flat burr grinder your choice will be largely based on your specific grinding requirements and unique tastes A barista who grinds multiple cups of coffee throughout the day might choose a flat burr mill because it produces less fines and reduces oxidation making it easier to store Another factor to consider is the amount of heat that a grinder generates during operation This is crucial because it can affect the taste and quality of your cup of coffee The more friction that a grinder produces and the more its likely to increase its temperature which can alter the flavor profile of your beans and lead to overextraction Flat burr grinders generate less heat than conical grinders This can give you a cleaner overall taste If youre looking for a coffee grinder that has flat burrs theres a wide range of options available from reputable brands such as Baratza and Eureka For instance the Fellow Ode Gen 2 is a popular choice because its easy to calibrate and offers a high degree of precision It is also very quiet and suitable for espresso It doesnt produce the same amount of fines as Baratza and other top models and it is difficult to achieve a mediumcoarse grind when grinding espresso Variable Grind Settings No matter what type grinding equipment you employ the process produces various sizes and shapes Measuring this in any sensible way is difficult except for equipment like laser particle diffraction analysis The majority of coffee grinders dont provide a precise measurement but instead have a set adjustment dials which allow the user to select among a variety of grind sizes commercial grinder Coffeee are usually marked with a series of dots or numbers that represent smaller and larger sizes The numbers are sometimes followed by arrows which indicate which direction the dial is supposed to move to make the grind more coarse or more fine Many grinders also come with visual representations to assist you in choosing the correct setting They include dots or series or a stepped adjustment system These visual representations are helpful but they are not exact guidelines and youll need to test different settings If the dots or numbers are close and are close together then they are well set If they are further apart then they are very coarsely set When deciding on a grinders setting it is important to be aware that even tiny adjustments can make a massive difference Dialing in a grinder is finding the ideal grind setting for the coffee and brewing method The optimal grind setting allows the most balanced and fullbodied taste to be exhibited while remaining within the acceptable limits of extraction This is a constant pursuit because even minor variations could result in coffee that has been over or underextracted For espresso a fine grind is the best because it maximizes the amount of water that comes into contact with the grounds in the short time for extraction Pourover French Press Aeropress and Turkish Coffee all benefit from a setting similar to powdered white sugar Easy Cleaning As coffee grinds pass through your grinder old grounds and oils are accumulated in the crevices The accumulated oils eventually turn rancid and begin to affect the flavor of your espresso Regular cleaning can help prevent the accumulation of stale oil in your grinder and help keep it running at its peak To clean your grinder start by disconnecting it from the power source and then removing the hopper Then remove the burrs Be careful not to damage the sharp burrs which are able to scratch or scratch the inside of your grinder If you have a grinder cleaner brush apply this on the burrs to remove any stuck on coffee If you dont have a grinder cleaner brush use a toothpick or soft brush to gently remove the ground coffee from the burrs Once youve removed the burrs as well as any other coffee particles wash the entire machine down with a dry cloth Whether youre using a burr grinder or a blade grinder cleaning your grinder on a regular basis is important The aroma and flavor of coffee beans are lost as soon as the beans are ground The best espresso is made with freshly ground coffee A grind that is too fine can cause bitterness and overextraction and a grind that is too coarse can result in under extraction and a weak flavor Cleaning your grinder regularly will ensure that it is in good condition and produces highquality grounds to make your morning coffee Remaining oily residues and allowing old ground coffee to build up in the nooks and crevices could result in clogged blades and poorerquality coffee The flavor of coffee can be affected by allowing coffee that is stale to accumulate on the burrs There are many ways to clean a grinder however one of the easiest is to use a coffee grinder cleaning tablet such as Urnex Grindz These tablets are made up of edible grains that bind with and remove coffee oil These tablets are an excellent alternative to soaking your burrs in a solution 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 a keyboard blower
