Grinding Your Gourment Coffee

Once the freshly roasted beans have been acquired, it is essential to give those beans the proper grind to prepare the gourmet coffee for brewing. The particular grind you choose will depend on your brewing method.

There are two types of coffee bean grinders—Blade Grinders and Burr Grinders.

Blade Grinders

Blade Grinders use metal blades to chop up the whole coffee beans.  The grind size varies from fine to coarse, and is controlled by how long you continue to run the grinder.

One problem with Blade Grinders is that they produce an uneven grind size, which leads to inconsistency in brewing.  Another problem is that excess heat may be generated when coffee is ground very fine. This heat can essentially re-roast the beans and may impart a burned taste to the coffee.

Burr Grinders

Burr Grinders come in two types—the Wheel Burr Grinder, which uses a high speed rotation, and the Conical Burr Grinder, which uses a slower rotation and is more expensive. Both types of Burr Grinders crush the whole coffee beans between a stationary surface and a moving grinding wheel.

Conical Burr Grinders are less noisy and messy than Wheel Burr Grinders, and are also better at handling oily or flavored coffees without clogging.

Burr Grinders are able to achieve a more consistent grind size than Blade Grinders because the grind size is controlled by the position of the burr.
