Blades or mills, conical or flat, slow or fast, with doser or no doser; There are numerous models of coffee grinders on the market, each with its own characteristics, but which one to choose to get a perfect espresso? In this article dedicated to all coffee lovers and especially to beginners, Caffè Italia offers some valuable tips for choosing the right coffee grinder for your needs.

Blades: for which shape, size and material to choose

To begin with, let's consider the blades of the coffee grinders, which have the function of grinding coffee into small particles of random size. Below we evaluate their shape, size and material.

  • Baldes Shape: The blades are available in different shapes, mainly we find flat or conical types. In general, we recommend choosing flat blades to grind the beans to be used for espresso and the conical ones for the preparation of infusion drinks that do not require superfine size control.
  • Size Dimensions: blade diameter is measured in millimeters and varies from about 40 millimeters for coffee grinders suitable for domestic use, up to a range of 80 millimeters for commercial coffee grinders. In general, we can say that the larger millstones guarantee faster and higher quality grinding
  • Material: Usually the blades are available in steel or ceramic and in some cases they are coated with titanium, to guarantee a longer life. The ceramic blades manage to better dissipate the heat ensuring the freshness of the grind. To produce very high quantities of coffee, however, we suggest steel blades, capable of grinding hundreds of kilos of coffee without having to be replaced.

The characteristics of the coffee grinders

Now let's analyze the technical characteristics of the coffee grinders and the materials used.

  • Grinding adjustment. On the market there are models of coffee grinders with doser or no doser. In the first type of grinder it is possible to dose pre-set quantities, while in grinders with no doser the regulation is continuous and it is possible to set infinite grinding variables.
  • Engine power. When choosing a coffee grinder it is good to analyze the power of the motor, which varies from about 100 to over 400 Watts. The more powerful motors offer longer work cycles, i.e. they grind more coffee and do it faster.
  • Build quality. Higher prices usually guarantee better build quality. Indeed, more metal parts and fewer plastic components can be found in more expensive coffee grinders. Elements such as buttons, switches, sliding controls, levers influence the functioning of the coffee grinder and it is therefore advisable to evaluate its construction.
