Burr vs Blade Grinding

There are two primary methods of grinding coffee beans: burr grinding and blade grinding. Manual grinders typically utilize burr grinding, while electric grinders commonly employ blade grinding. The main difference between the two lies in the mechanism used to crush the beans.

Burr grinding involves two abrasive surfaces, known as burrs, that are positioned close together. The beans are captured between these burrs and crushed to the desired size by the rotating action of the burrs. Blade grinding, on the other hand, uses blades that slice through the beans, resulting in a less consistent grind.

Crushing vs Slicing the Beans

When it comes to grinding coffee beans, the method used to reduce them to the desired size can have a significant impact on the resulting taste of the brewed coffee. Manual grinders crush the beans between the burrs, creating a more uniform particle size. This consistency contributes to a more even extraction of flavors during the brewing process.

On the contrary, blade grinding in electric grinders tends to slice the beans, resulting in a less uniform grind. This unevenness can lead to extraction inconsistencies, where some particles are over-extracted, while others are under-extracted. Ultimately, this can result in a less balanced and less flavorful cup of coffee.
