What's your flavor? There are three different kinds of grinders. There is the blade grinder-if you let the machine grind for a longer time it will give you finer granules and in turn give you the best drink. These machines have high speed blades which cut the beans into bits. The next in line is Burr grinders. These are more sophisticated and improved than the blade machine; they are made up of two plates with sharp cutting edges that work on your beans. The beans are grounded in series until you get a finer grain depending on your liking. There are also two types of burr grinders. The first is the Flat burr whose plates are placed on top of the other; they are mostly used to acquire grinds that are fine to make espressos. Number two is the conical burrs.For these grinding plates are not similar. The plates move slowly while grinding hence retaining the original aroma. The Manual crank grinder is one that uses physical force (your arm) to grind. More than what you wanted The grinders are high performance machines. They can actually multi-task. You can still grind your spices and nuts. The problem is the smell of your spices will still remain. For best results and a sweet cup of coffee use the grinder together with an espresso machine.
