To get the best coffee experience, you require uniform distribution of the particles. This can only be achieved using a burr mill. This is why coffee snobs loathe burr grinders.

Inconsistent Grinds

You may have noticed your grinding results aren't consistent if you've used a blade grinder over a long period of time. The grinder is likely to become dull and worn. As the grinder wears down, it will chop up beans into different-sized pieces. This will result in different degrees of coarseness. With the different sizes of coffee particles, it's difficult for your coffee maker with grinder maker to extract an even, consistent flavor.

A blade grinder uses an e-rotating blade that resembles a propeller to break the beans. It basically chops the beans into smaller and smaller chunks and then drops them through a screen and into a catcher.

A burr grinder is a much bigger machine, with a large motor and two grinding burrs. The burrs are set to an exact distance from each other which determines the fineness of the coffee that you grind.

If the burrs get too close, they will crush rather than cut the beans. The result is a more fine and less coarse grind. They may also be brittle and affect the taste of your coffee.

A blade grinder may produce a mix of large fragments, dust-sized particles, and everything between. Different grind sizes produce at different rates, resulting in an inconsistent and often bitter cup of compact coffee grinder.

The lack of uniformity also results in problems with the tamping process and filtration. With a burr mill, you can get an evenly ground particle size, allowing for more even tamping and filtering that prevents over-extraction and weak beers. With a blade grinder it is more difficult to attain an even grind and you might be tamping from side to side or using the Stockfleth method (which requires some practice).

The high speed and heat produced by blade grinders are another problem. This can burn the grounds and produce a bitter flavor. Burr grinders are cooler and don't produce as much heat, which preserves the flavors of the bean.

Another drawback of the blade commercial grinder is that it's extremely easy to over-grind your beans. Running the grinder continuously generates a lot of heat, which can cause your grounds to become excessively extracted, leading to bitter beverages.

Blade grinders offer a variety of advantages, including their low cost and speedy operation.
