Grinding whole bean coffee is the first requirement in making the perfect cup of coffee. The two types of coffee grinders for home use are burr grinders and blade grinders. Blade grinders utilize a spinning blade that chops the coffee beans resulting in an inconsistent particle size and can alter the taste of coffee. Burr grinders produce a consistent grind by crushing the coffee beans between a rotating and stationary set of burrs, creating a richer and smoother extraction.
