There are two basic types of coffee grinders: burr and steel blade. Burr grinders tend to be more expensive, but make a better cup of coffee. Many companies make both types to suit all customers.
The burr coffee bean grinder design is the best for most brewing; they consistently get high marks in coffee grinder reviews. The grinding process results in less heat, which results in more flavor. Burr grinders can be adjusted for different degrees of fineness, which allows you to get the consistency you want. Each burr grinder has its own range as far as the different fineness settings, with some better for an espresso machine and others for a traditional drip coffee maker. Check when purchasing to be sure you’re getting the right grinder for your needs.
Blade grinders use steel blades and have electric motors to grind coffee beans. The degree of fineness is determined by how long the machine is left on during the grinding process. More heat results from this process, which results in a loss of aroma and flavor in the finished product. A blade grinder is less expensive and for this reason are most often used in homes.
