The Benefits of Using a Coffee Grinder Experts believe that adding a coffee grinder to your morning routine is a great way to improve The higherend models feature burr grinders which are made up of two grooved surfaces that can be adjusted for a more consistent grind In contrast to a blade grinder these kinds of grinders stop the oxidation of your ground and ensure that they are even in size wwwcoffeeeuk are a powerful type of coffee grinder which makes use of angled opposing cutting surfaces to break down whole beans into small particles They produce fewer fines also called dust than blade coffee grinders You can regulate the size of particles by adjusting the distance between the burrs There are two primary types of burrs which are conical and flat The differences between flat and conical burrs arent obvious but significant Each type has their own strengths Blade grinders feature sharp bladeshaped teeth which bludgeon the coffee with each passing Burr grinders employ a pair of disc shaped burrs to grind beans The two burrs can be moved closer together or further apart to set the desired size of grind between coarse and fine When properly set they produce a very regular grinding process with fewer pieces and no heating A topquality burr grinder must be lubricated to reduce friction and prolong the lifespan of the blades They should also be able to be cleaned easily reducing the buildup of coffee residue While there are some handpowered burr grinders commercial flat burr grinders are nearly always electrically powered as they require more power than can be generated by a human hand alone Within each category of burr shape there could be additional variation between different brands and models of grinders These differences arent due to the shape or the geometry of the burrs but rather how their pattern is related to the distribution of particle size For instance certain conical burr grinders like the Niche Zero have very low retention whereas other flat burr grinders like the Iberital MC2 have a high retention Some coffee lovers claim that certain burr types can bring out certain flavors in the roast or bean But this is a subject that is largely based on speculation and not scientifically proven Flat Burrs Flat burrs are flat plates with sharp ridges which face each other and crush the coffee beans between them Theyre the most commonly used burrs found in grinders for home and commercial use and are typically the primary type used in manual grinders Flat burrs may be more difficult to maintain the same distribution of grind sizes than conical ones due to the fact that their cutting edges are angled and they can leave behind fines or grit This can result in poor extraction and bitter flavors This isnt a major issue for everyone since the latest developments in burr geometries allow for the same consistency in size distribution as flat burrs When it comes to deciding between the best conical or flat burr grinder the choice will be largely based on your specific grinding requirements and individual preferences A barista who grinds many cups of coffee throughout the day might choose a flat burr mill because it produces less fines and reduces the rate of oxidation which makes it easier to store Another factor to consider is the quantity of heat a grinder produces during operation This is important as it can affect the flavor and quality of your cup coffee The more friction that grinders create and the more heat it generates This can alter the taste of your beans or result in excessive extraction Fortunately flatburr grinders produce less heat than their conical counterparts so they can provide you with a cleaner taste overall There are many options for a coffee maker with flat burrs made by reliable manufacturers like Baratza and Eureka The Fellow Ode Gen 2 is popular because its easytocalibrate and offers a high level of precision It also has a low noise level and is ideal for espresso grinding However it doesnt create as fine a grind as Baratza or other top models and isnt able to produce moderately coarse grinds 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 It is difficult to quantify this accurately unless you have expensive equipment like laser particle difffraction Instead of providing an exact measurement of particle size the majority of coffee grinders have adjustable dials that allow the user to choose between a range of grind sizes Dials are marked by numbers or dots to indicate smaller and larger sizes The numbers are sometimes followed by arrows which indicate which direction the dial should move to make the grind more coarse or finer Many grinders also come with visual representations to assist you in choosing the correct setting These can be a series or dots or an adjustable stepped system These visual representations are helpful but they are only general guidelines and you will need to test different settings If the dots or numbers are close together then they are very precisely set If they are farther apart then they are very coarsely set When choosing a grinders setting its important to keep in mind that minor adjustments can make a huge differences and its important not to go too far out of the intended range when making adjustments The dialingin process of grinding is the process of determining the most optimal grind setting for a specific coffee and brewing method The best grind setting allows the brew to be able to produce the fullest and balanced flavor possible while remaining within a reasonable range for extraction limitations This is a constant goal as even slight variations from the sweet spot could result in under or overextracted coffee For espresso a fine grind is optimal as it increases the amount of water that will come into contact with the ground during the short time to extract A setting that is similar to powdered sugar works well for a variety of methods of brewing such as pourover 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 Then the accumulated oils go rancid and can affect the taste of your coffee Regular cleaning can help keep the accumulation of stale coffee oil and can keep your grinder running at its peak To clean your grinder start by unplugging it then taking out the hopper Then 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 residue that is stuck to the burrs Instead use a toothpick or soft brush to gently remove ground beans from burrs After you have removed the burrs and any other coffee particles from the machine clean it off with a clean dry cloth Cleaning your grinder regularly is crucial whether you use a burr or blade grinder Coffee beans lose aroma and flavor when they are ground The best cup of coffee comes from freshly ground beans Grinders that are too fine cause bitterness and overextraction as well as grinds that are too coarse can cause underextraction and a weak or thin flavor Cleaning your grinder regularly will ensure it remains in good working order and produces quality grounds for your morning cup of coffee Coffee residues and oily grounds can cause the blades to become blocked and result in poor quality coffee The taste of coffee may be affected by allowing coffee that is stale to build up on the burrs There are several ways to clean your grinder but the most effective is to make use of a tablet for cleaning your coffee grinder such as Urnex Grindz These tablets are made from edible grains that bind 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 clean your burrs using a brush or blowing them off with compressed air or an air blower on your keyboard
