10 Real Reasons People Dislike Blade Grinder Blade Grinder
Blade Grinder - Why You Shouldn't Use One
A blade grinder uses an e-type propeller (think blenders) to chop coffee beans. They are cheaper than burr mills, and easier to clean, but they don't create a uniform ground and can result in bitterness and over-extraction in your brew.
To get the best coffee experience, you require uniform particle distribution. This is only possible using burr mills. It's no wonder that coffee experts hate burr grinders.
Inconsistent Grinds
If you've been using a blade grinder for a while it is likely that your grinding results have changed. The grinding device is likely be worn out and dull. As the grinder gets older it will produce different sized pieces of beans. This produces grounds with varying levels of coarseness. With these different-sized coffee particles, it's hard for your coffee maker to produce an even, consistent flavor.
Blade grinders break the beans with a rotating blade that resembles an engine. It basically chops the beans into smaller and smaller pieces that are then thrown through a screen into the catcher. This method is efficient however it's not the best grind possible for your brew. Burr grinders are a better choice. A burr grinder is a larger machine that has a powerful motor and two grinding burrs. The burrs are placed at a specific distance from one another which determines the fineness of the coffee that you grind.
If the burrs get too close, they pulverize rather than cut the beans. The result is a finer and less coarse grind. They can also be brittle, which can affect the flavor of your coffee. On the other however, if the burrs are spaced too separated, they could create large chunks of coarsely-ground coffee. It is essential to select a coffee grinder that has an adjustment that is in line with the level of coarseness you want.
A sharp, properly adjusted blade will yield a consistent and fine grind for your coffee. If you notice that your grind becoming increasingly more uneven, it's probably an ideal time to replace the blade or burrs. It is also advisable to change the grind setting if you haven't done so before to help you achieve an even and consistent grind.
It's also important to note that if your grinder creates ground that is clumpy it is a sign of worn-out or damaged blades. The clumping happens when tiny particles bind to each other and larger pieces of ground are formed, producing larger granules that don't dissolve in water. This is more frequent as your burrs get duller.
Uneven Extraction
The size of your coffee grounds is important to extract flavor, whether you're making a French press, pour-over or drip brew. Uneven ground sizes cause uneven extraction, creating an unbalanced cup.
The beans are cut and shred indiscriminately as they pass through a blade mill, resulting in an uneven distribution of grind particle size. A blade grinder produces smaller fragments, small particles and everything between. These different grind sizes are extracted at a different rate, which results in the coffee drink that is often bitter and inconsistent.
In addition, the lack of uniformity creates problems when tamping and filtration. With a burr mill you can get a uniform particle size, which allows for better tamping and filtration, which helps to prevent over-extraction. If you use a blade grinder, it is more difficult to get an even grind, and you might encounter tamping that is inconsistent from side to side or using the Stockfleth method (which requires some time to master).
Another issue with blade grinders is their speed and high heat generation. They can cause the ground to burn and produce a bitter flavor. Burr grinders are more cool and don't generate as much heat, which preserves the flavors of the bean.
The blade grinder has one final disadvantage: it is very easy to grind your beans too fine. Running the grinder continuously generates a lot of heat, and eventually causes your grounds to become excessively extracted, which can result in bitter brew. To avoid this, always stop the grinder prior to switching it back on.
Using a blade grinder is a simple and inexpensive way to grind your own coffee at home, but it's not the ideal choice for those who are serious about their coffee-making. For the most effective results, you'll need to make use of a burr mill and whole beans. Consider investing in a top coffee grinder that will meet all your requirements.

Selecting the right grinder is an important decision that will affect the quality of your brewing and overall cup quality, so consider your budget, your space, and your preferred method of brewing when making your choice.
manual vs electric coffee grinder Coffeee burned Grounds
With the blade grinder, you're using a sharp blade that rotates like a blender at a rapid speed to chop up the beans. As the blade rotates at a rapid pace, heat is produced which may burn up the coffee grounds. These particles will alter the taste of your coffee and aren't ideal to brew.
To ensure a top-quality experience the uniform distribution of particles is essential to ensure the best flavor extraction. This consistency is impossible with a blade grinder that is able to break the beans into small and large pieces. A burr mill, on the contrary, produces a uniform distribution of particles sizes that can be reproduced over a variety of beverages.
Blade grinders have many advantages, such as their low cost and quick operation. However, they also have some disadvantages for instance, the fact that they produce heat when they are in use, produce inconsistent grind sizes, and lack control over the final particle size. With a bit of practice there are ways to maximize results despite the inherent limitations of this kind of grinder.
When used in conjunction with a burr grinder the user can easily adjust the distance between the grinding discs to fine-tune the exact ground size of their preference. This allows them extract the desired flavours every time from their favorite roasted bean. It takes a lot of time to make a great brew using a blade grinder.
An angle grinder is a powerful tool that should be utilized only by trained personnel. It can cause grinding burn if employed incorrectly. This can cause localized changes to the metal surface of the workpiece. This could cause cracks that, if not checked, could lead to macropitting and tooth fracture.
Grinding burns can be caused by a variety of reasons, such as excessive grinding pressure or insufficient cooling. It can also be caused by poor training for operators. Wear the correct safety equipment when using an angle grinder. This includes safety glasses as well as a face shield and steel toe boots. This will stop any sparks of heat from flying off the wheel and hitting people or equipment near by. The sparks can be as hot as 3,600 degF, and are capable of burning through materials such as paint or metal.
Disappointing Brew
A blade grinder chops up your beans in a random fashion, leaving you with grounds that are all different sizes. The uneven ground extracts coffee at different rates, which results in the cup being bitter or weak of coffee. The issue is that it can ruin the balance that makes a good cup of coffee. Soluble compounds in the beans are removed in time, and this creates the flavor that makes your coffee delicious.
You've probably heard that using the burr mill rather than blade mills is the best way for the best beverage. Many people don't even know what a burr mill does. They purchase the flimsy blade grinders that are uncontrollable and difficult to control they can find in supermarkets and kitchen-type places.
The basic idea is that these grinders feature a double-pronged blade in the middle of a chamber that spins rapidly and chops anything it strikes such as coffee beans. Press a button to activate it and the blade chops up your beans into a variety of different sized pieces. The smaller pieces drop to the bottom of the chamber, and are chopped again, while the larger pieces remain at the top. This causes uneven grounds, which are difficult to measure.
These grinders can also burn your beans and ruin the coffee. The heat also takes away some of the flavor from the beans, which means you're left with a mediocre cup of coffee.
If you have been grinding your coffee using a blade mill, it's time to upgrade to a more efficient. A burr grinder can do the job for a fraction of the price and provide a better result. It's well worth the investment. Try a manual burr mill like the Rhino Hand Grinder if you want more control over your beverage. These grinders feature burrs however they are powered by the crank, which gives more control than an electric or plug-in grinder.
