There are many types of coffee makers with built-in coffee grinders, with options ranging from conical burr to flat burr. We can’t simply say who is good and who is bad when it comes to conical or flat grinding. Most professional coffee drinkers feel that flat burrs give a more consistent grind, which results in a cleaner cup. conical burrs, on the other hand, yield more fines and produce a cup with more body feel.
| Two common types of coffee grinders | |
| Conical burr | Flat burr |
| More of a V shape, with the center burr fitting into the outer burr, both of them also lined with sharp-edged grooves that cut up the beans as they press together. | Consist of two flat, ring-shaped burrs lined with grooves that break up the beans as the burrs press together. |
