Blade Grinder – Why You Shouldn’t Use One

Blade grinders are equipped with a blade that looks like a propeller (think blenders). They are used to chop coffee beans. They are less expensive than burr grinders and are easy to clean but they don’t yield uniform grounds and can cause over-extraction and bitterness in your brew.

A first-class coffee experience demands uniform particle distribution which can only be achieved by using a burr grinder. It’s no wonder that coffee snobs hate burr grinders.

Inconsistent Grinds

If you’ve used a blade grinder for a while it is likely that your grinding results have changed. The machine is likely to wear out and dull. As the grinder wears down, it will chop up beans into different sizes. This can result in different degrees of coarseness. With these different-sized coffee particles, it’s difficult for your coffee maker to extract the right balance and consistency in flavor.

Blade grinders use the same propeller-like blade to break beans. It basically chops the beans into smaller and smaller chunks that are then thrown through a screen into a catcher. This method is efficient, but it doesn’t produce the best grind possible for your drink. Burr grinders are a better option. A burr grinder is a larger machine that has a powerful motor and two grinding burrs. The burrs can be set at a specific distance and will determine the degree of coarseness of the coffee being ground.

If the burrs are close to each other, they will crush the beans, rather than cutting them. This means that the resultant grounds are less coarse and more fine. They may also be brittle and alter the flavor of your coffee. On the other hand if the burrs are spaced too far apart, they will result in large chunks of coarsely-ground coffee. It’s crucial to choose the coffee grinder with an adjustment that is in line with the level of coarseness you want.

A blade smart grinder creates an assortment of larger fragments, smaller particles, and everything in between. The different sizes of grinds produce at a different rate, resulting in the coffee drink that is usually bitter and inconsistent.

Lack of uniformity can also cause problems with tamping or filtration. With a burr mill, you can get a uniform particle size, allowing better tamping and filtration which helps to prevent over-extraction. With a blade grinder, it is more difficult to achieve an even grind, and you might find yourself tamping from side to side or using the Stockfleth method (which takes some practice).

The high speed and heat produced by blade grinders is a different problem. This could cause the ground to burn and create a bitter taste. Burr grinders create less heat and are cooler, which preserves the flavor of the beans.

The blade grinder has a final 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 cause a bitter brew. To avoid this, always stop the grinder before switching it back on.

Grinding burns can be caused by many factors, including excessive grinding pressure or insufficient cooling. It could also be caused by improper 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.
