Blade Grinder - Why You Shouldn't Use One

A blade grinder uses an e-type propeller (think blenders) to chop coffee beans. They are much cheaper than burr grinders and easy to clean, but they do not produce uniform grounds and can cause over-extraction and bitterness in your coffee.

A top-quality coffee experience requires uniform distribution of particles which can only be achieved by using the burr grinder. It's no wonder that coffee snobs hate burr grinders.

Inconsistent Grinds

If you've used a blade grinder for a while there's a good chance that your grinding results have become inconsistent. The grinder is likely to wear out and dull. As the grinder ages, it will produce different-sized pieces of beans. This produces grounds with varying degrees of coarseness. With these various-sized coffee particles, it's hard for your coffee maker to produce the right balance and consistency in flavor.

A blade grinder uses an e-rotating blade that resembles a propeller to break beans. It chops the beans up into smaller and smaller pieces which are then dropped into a catcher through the screen. This technique is efficient however it doesn't provide the finest grind possible for your brew. An alternative is the burr grinder. A burr grinder has a powerful motor with two grinding burrs, and is a bigger machine. The burrs can be placed at a specific distance, which will determine the quality of the coffee being ground.

If the burrs are too close, they will crush rather than cut the beans. This results in a finer and less coarse grind. They are also more fragile, which could negatively impact the taste of your coffee. If the burrs, however, are not evenly spaced they'll result in large chunks of coffee that have been coarsely ground. It is essential to choose an espresso grinder that's setting is in line with the desired coarseness.

A sharp, well-adjusted blade will result in an even and fine grind for your coffee machine with grinder. If you find that your grind is becoming more uneven, it's best to replace the blade or burrs. You should also think about changing the grind setting in case you haven't already to aid in achieving a more uniform grind.

If your grinder produces clumped up grounds it could be an indication that the blades have worn out or damaged. The clumping occurs due to small particles adhering to one another and larger pieces of grounds, creating larger granules that do not dissolve well in water. As your burrs become more and more dull this will occur more often.

Uneven Extraction

Whether you're brewing drip, French press, or pour-over the size of your ground plays an crucial role in preserving flavor. Uneven sizes of the grounds can result in uneven extraction and a sloppy cup of coffee.

The beans are cut and shred indiscriminately when they go through the blade mill, resulting in an uneven distribution of grind particle size. A blade grinder can produce an assortment of large pieces, dust-sized particles, and everything else. Different grind sizes produce at different rates, resulting in an inconsistent and often bitter cup of coffee.

In addition, the lack of uniformity causes problems with tamping and filtration. With a burr mill, you can achieve an even particle size, allowing for better tamping and filtration which helps to prevent over-extraction. With a blade grinder (Resource), it is more difficult to achieve an even grind and you might encounter tamping that is inconsistent from side to side or using the Stockfleth method (which takes some practice).

The high speed and the heat produced by blade grinders is another issue. This could cause the ground to burn and create a bitter taste. Burr grinders are much cooler and don't produce the same amount of heat, which helps preserve the flavor of the bean.

The blade grinder has one last disadvantage: it's easy to grind your beans to a fine. Keeping the grinder running continuously generates a lot of heat, which can cause your grounds to become excessively extracted, leading to a bitter brew. To avoid this, always stop the grinder before turning it back on.

The use of a blade grinder is an efficient and cost-effective method of grinding your own coffee at home, but it's not the ideal option for those serious about their brewing. You'll want to stick with whole beans and use burr grinders for the best results. Make sure you invest in your coffee brewing experience and purchase an efficient grinder that will meet every coffee need!

Take a look at our top picks of the best burr mills on the market if you're looking to upgrade your blade grinder. Selecting the right grinder is a crucial decision that will affect the quality of your brewing and overall cup quality therefore, you should consider your budget, your space, and your preferred method of brewing when making your choice.

Grounds burned Grounds

With a blade grinder it's a sharp blade that spins like a blender at high speed to break up the beans. As the blade moves at a rapid pace there is a lot of heat produced that can cause a fire to the coffee grounds. These particles will alter the flavor of your coffee and aren't suitable to brew.

A premium coffee experience demands a uniform particle distribution to ensure optimal flavor extraction during the brewing process. This is not possible with a blade mill that breaks the beans up into small and large pieces. A burr grinder, on the other hand, achieves an even distribution of particles that can be replicated over a wide range of brews.

Blade grinders come with many advantages, such as their low price and quick operation. However, they do have a few disadvantages, such as the fact that they generate heat when they are in use, produce inconsistent grind sizes and have no control over the final particle size. With a little bit of practice however, there are ways to optimize results despite the inherent limitations of this type of grinder.

When used with a burr mill, the user can easily adjust their desired grind size by adjusting the gap between the discs. This allows them to extract the flavor they desire every time from their favourite roast beans. However, creating a quality brew with a blade grinder is a process that requires a lot trial and error.

An angle grinder is a powerful tool that should only be used only by trained professionals. When operated incorrectly it can result in an unsafe condition known as grinding burn, which causes localized changes in the metallographic structure of the workpiece's surface. This can cause cracks that, if unchecked could eventually lead to macropitting and tooth fracture.

Grinding burn can be caused by a variety of factors, including excessive grinding pressure or insufficient cooling. It can be caused by inadequate operator training. If you plan on using an angle grinder, be sure you wear the appropriate PPE, including gloves and a face shield, safety glasses, steel toe boots and long sleeves. This will prevent hot sparks from flying off the wheel and hitting nearby equipment or people. Sparks can reach temperatures as high as 3,600 degF and can be able to burn through materials such as paint or metal.

Disappointing Brew

A blade grinder can chop your beans up indiscriminately and leave you with different-sized ground. The unevenly sized grounds extract at different rates in your coffee maker, and this leads to a bitter or weak cup of compact coffee grinder. This ruins the balance of a great cup. The soluble components from the beans are extracted slowly and create the flavor.

You've probably heard it said that using the burr mill rather than a blade mill is the best grinder machine way for a great brew. Many people don't understand what a burr mill does. They buy the flimsy blade grinders that are uncontrollable and difficult to control they can buy at supermarkets and kitchen-type places.

Basically, these cheap grinders feature a double-pronged blade in the middle of a chamber that spins rapidly and chops anything it hits such as coffee beans. You press a button activate the device and the blade cuts up your beans into a variety of different-sized pieces. Small pieces drop to the bottom of the chamber, and are then chopped up again, whereas the larger pieces remain at the top. This causes uneven ground which are difficult to measure accurately - which is why you aren't sure of how much ground coffee your grinder produced.

Another issue with these grinders is that they produce lots of heat when they grind, which could damage your beans and ruin the coffee you drink. The heat can also take away some of the flavor of your beans. This can leave you with a not the best cup of coffee.

If you've grind your own coffee using a blade grinder, it's time to retire it and upgrade to a better. A burr grinder will accomplish the job for only a fraction of the cost and will give a superior result. It's worth it. If you want more control over the brew Try a manual grinder such as the Rhino hand grinder. These grinders feature burrs but are powered by turning a crank, which provides more control than an electric coffee grinder or plug-in grinder.
