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 are easy to clean but they do not produce uniform grounds and can cause excessive extraction and bitterness in your coffee.

To get the best coffee grinders types experience, you need uniform particle distribution. This can only be achieved using a burr mill. This is why coffee snobs loathe them.

Inconsistent Grinds

If you've used a grinder with a blade for some time it is likely that your grinding results have changed. The grinder is likely to 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. It's a challenge for your coffee brewer to get an even, balanced flavor with these various-sized particles.

Blade grinders break beans by rotating a blade that resembles an engine. It essentially chops the beans into smaller and smaller pieces, which are then dropped through a screen and into the catcher. This technique is efficient however it doesn't provide the most efficient grind for your drink. Burr grinders are a better alternative. A burr grinder is equipped with powerful motors, two grinding burrs and is a larger machine. The burrs can be placed to a certain distance and will determine the degree of coarseness of the ground coffee.

When the burrs get too close, they will crush rather than cut the beans. As a result, the resultant grounds are less coarse and finer. They also tend to be brittle, which can negatively affect the taste of your coffee. On the other side when the burrs are too separated, they could result in large chunks of coarsely-ground coffee.

It's also important to note that if your machine produces clumped up grounds it is an indication of worn or damaged blades. The clumping occurs when tiny particles bind to one another, and larger pieces of ground form, making larger granules that won't dissolve in water. As your burrs become more and less dull it will happen more frequently.

Uneven Extraction

No matter if you're using drip, French press, or pour-over the size of your ground plays an crucial role in preserving flavor. Uneven ground sizes cause uneven extraction, creating an unbalanced cup.

The beans are sliced and shredded in a random manner when they go through the blade mill, resulting in an unbalanced distribution of the size of the grind particles. A blade grinder may produce an assortment of large fragments that are dust-sized, as well as everything else in between. Different grind sizes extract at uneven rates which results in a sloppy and often bitter cup of coffee.

Inconsistency can cause problems with tamping or filtering. With a burr mill, you can get an even particle size, which allows for better tamping and filtering, which can prevent excessive extraction. With a blade grinder it is more difficult to get an even grind, and you might find yourself tamping 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. This could cause the ground to burn and produce an bitter flavor. Burr grinders are cooler and don't generate as much heat, which helps preserve the flavors of the bean.

A final downside of a blade grinder is that it's easy to over-grind your beans. The grinder can generate plenty of heat and your beans will eventually be pushed to the limit. This will result in a bitter drink. To avoid this, you must pause your grinder before turning it back on.

The small pieces are pushed to the bottom of the chamber and are again chopped, while the larger pieces remain at the top.
