To brew the perfect espresso you need to choose the grinder that is right for your machine. The grind size and consistency of the espresso is directly affected by your grinder. The two main types of coffee machines grinders are blade grinders and burrs grinders.

Burr mills are able to grind coffee beans with precision, leading to a smoother extraction of espresso. The grinder produces less heat, thus preserving coffee’s aromas and tastes.
To cut coffee beans, the spinning blades of a blade grinder are used. Blade grinders, while less expensive and easily accessible, aren’t the best choice for making coffee espresso.

The burr grind can be fine-tuned to the espresso machine specifications, guaranteeing a consistent and reliable extraction. On the other hand blade grinders produce both coarse and very fine particles which may lead to an over or under extraction.
