The right coffee grinder plays a big role in making a great cup of coffee. A fresh aromatic and flavourful cup of coffee is also dependant on the fineness or coarseness of the grind, which should be neither too fine nor too coarse. The simplest coffee grinders are those with blades. But they don’t really “grind” your coffee beans. They smash them to bits with two very fast moving blades. Burr grinders really do “grind”. They grind beans between two burred plates. The plates, or “burrs”, are flat in some models and conical in others. One plate remains stationary, while the other spins around. Burr grinders give the maximum flexibility and precise and consistent grind.
