Blade Grinder - Why You Shouldn't Use One
Blade grinders have blades that resemble a propeller (think blenders). They are used to chop coffee beans. They are much cheaper than burr grinders and are easy to clean but don't produce uniform ground and can cause excessive extraction and bitterness in your brew.
To get the best coffee experience, you need uniform particle distribution. This can only be achieved by using a burr mill. It's no wonder that coffee people who are snobs dislike burr grinders.
Inconsistent Grinds
You may have noticed your grinding results are inconsistent when you've been using a blade grinder for a long time. The grinder is likely to wear out and dull. As the grinder wears out it will cut beans into different sizes. This results in ground with varying levels of coarseness. It's challenging for your coffee brewer to get an even, balanced flavor with these different-sized particles.
A blade grinder cuts the beans with a rotating blade that resembles propellers. It cuts the beans into smaller and smaller pieces which are then tossed into a catcher, which is then filtered through the screen. This method is efficient however it's not the most efficient grind for your drink. A better option is a burr grinder. A burr grinder comes with an efficient motor, two grinding burrs and is a much larger machine. The burrs are set at an exact distance from each other which determines the fineness of your ground coffee.
When the burrs are too close to each other, they will crush the beans, rather than cutting them. This means that the ground that results are less coarse and more fine. They may also be brittle and alter the flavor of your coffee. On the other side if the burrs are spaced too far apart, they will produce large chunks of coarsely ground coffee. It is essential to select the coffee grinder with an adjustment that is in line with the level of coarseness you want.
A sharp blade, when adjusted correctly, will result in an even and consistent grind for your coffee. If you notice your grind is becoming more uneven, it's probably a good idea to replace the blade or burrs. You should also think about changing the grind setting if you haven't before to help you achieve a more uniform grind.

The clumping happens because tiny particles bind to each other and larger pieces of ground are formed, creating larger granules which don't dissolve in water. This will happen more often as your burrs get duller.
Uneven Extraction
The size of your coffee grounds is vital for flavor extraction, regardless of whether you're using a French press pour-over, drip brew or pour-over. Uneven ground sizes cause uneven extraction, leading to an unbalanced cup.
When the beans are pushed through a blade grinder they are cut and shredded randomly, leading to an uneven distribution of grind particle sizes. A blade grinder can create an assortment of large pieces, dust-sized particles, and everything else. The different sizes of grinds extract at an uneven speed, creating the coffee drink that is often bitter and inconsistent.
In addition, the lack of uniformity causes problems with tamping and filtration. With a burr mill, you can get a uniform particle size, allowing better tamping and filtering, which can prevent excessive extraction. With a blade grinder it is more difficult to achieve an even grind. You may be tamping from side to side or using the Stockfleth method (which takes some time to master).
Another problem with blade grinders is their high speed and heat generation. This can burn the grounds and cause a bitter taste. Burr grinders create less heat and are cooler, preserving the flavor of the beans.
The blade grinder has one last disadvantage: it's easy to grind your beans too fine. The grinder will produce plenty of heat and, eventually, your beans will be pushed to the limit. This can result in a bitter brew. To avoid this, you must stop your grinder prior to switching it back on.
A blade grinder is an efficient and affordable method of grinding your own coffee at home, but it's not the best option for those who are serious about their brewing. You should stick to whole beans and a burr grinder to get the best results. Invest in a quality coffee grinder that can meet all your requirements.
We've compiled a list of our top choices of the best burr mills on market if you're looking to upgrade your blade grinder. The type of grinder you choose will impact the quality of your brewing and the quality of your drink. Consider your budget, space, and preferred brewing method before making a decision.
Grounds Burned Grounds
With the blade grinder it's a sharp blade that spins like a blender at a rapid speed to cut the beans. The blade's speedy movement creates heat, which can ignite some of the coffee grounds. These particles will alter the taste of your coffee and are not suitable for brewing.
For a truly exceptional experience the uniform distribution of particles is essential for the best flavor extraction. Since blade grinders break the beans into varying size pieces, small and large it is impossible to achieve this level of consistency. A burr grinder, on the other hand can ensure an even distribution of particles that is reproducible across a variety of types of brews.
While the benefits of a blade grinder are its low cost and speedy execution, its main disadvantages are that it produces heat when used, causes inconsistencies in grind size, and has no control over the final particle size. With a bit of practice however, there are ways to optimize results despite the inherent limitations of this kind of grinder.
When a burr mill, the user is able to easily adjust their desired grind size by adjusting the gap between the discs. This lets them get all the desired flavours from their favourite beans each time. However, making a great beverage using a grinder takes a lot of trial and error.
An angle grinder is a potent tool that should only be used only by qualified personnel. It can cause grinding burn if it is used improperly. This causes localized changes to the metal surface of the workpiece. This can lead to cracking, which, if not checked, can eventually lead to macropitting and teeth fracture.
Grinding burn is a serious problem that can be caused by a variety of reasons, including excessive grinding pressure, inadequate cooling, or inadequate training for operators. Wear the correct safety equipment when working with an angle grinder. This includes safety glasses, a face shield and steel toe boots. This will stop any sparks of heat from flying off the tool and hitting people or equipment nearby. Sparks can reach temperatures as high as 3,600 degF, and are capable of burning through materials such as paint or metal.
Brew that is not what you expected.
Blade grinders chop your beans in a random fashion and leaves you with ground which are of different sizes. These uneven grounds release at different rates in your coffee maker, and this leads to a bitter or weak cup of coffee. This affects the balance of a good cup. The soluble components from your beans are slowly extracted, creating the flavor.
You've probably heard that using a brewing burr grinder instead of a blade is the best way to guarantee the best beverage. Many people aren't aware how to use a grinder or even what it is, so they buy one of the cheap, uncontrollable blade grinders that are readily available in kitchen and grocery store places.
Basically, these cheap grinders have a double-pronged blade in the middle of a chamber that spins quickly and chops up anything it hits including coffee beans. The blade is activated by pressing a button. It then chops your coffee beans into different size pieces. The smaller pieces fall to the bottom and are chopped again, while the large pieces stay towards the top of the chamber. This results in uneven grounds that are hard to measure accurately - which is the reason you can't be sure of how much ground coffee you made with your grinder.
Another issue with these grinders is that they generate plenty of heat as they grind, which could cause the beans to burn and ruin your coffee. The heat can also take away some of the flavor your beans, and you're left with a bland cup of coffee.
If you've grind your own coffee with a blade grinder and you're ready to get rid of it and upgrade to a more powerful. A burr mill will do the job at a fraction of the cost, and will produce a much superior result. It's worth it. Try a manual burr mill like the Rhino Hand Grinder if you want more control over your beverage. These grinders feature burrs but are powered by turning an engine, which gives more control than an electric or plug-in grinder.
