If you are serious about your coffee, you will notice a profound difference when you use a burr mill instead of grinder. Grinders have a little blade at the bottom and just continue to beat up the same grounds. With a burr mill. the beans go through the grinding process just once so you wind up with a consistent ground size. This burr mill by Cuisinart holds a half a pound of beans in the hopper. You set how finely you want your coffee ground and then slide the bar to the number of cups of coffee you are making and this baby does the rest.
