Even some of the most avid coffee drinkers are not aware of what a coffee grinder is. The majority of coffee drinkers go to cafés and coffee shops to get their regular shot of coffee, and so they are not used to making their own and have never used a coffee grinder. Even some people who are used to making their own coffee get the coffee packaged in a bag or otherwise ready to brew.
Knowing what a coffee bean grinder is will be hugely to your own benefit so if you ever go to make your own roast of coffee in the future you will get the freshest, most delicious brew of coffee each and every time.
There are actually quite a few things that you will want to be aware of when it comes to a coffee grinder. For one, the flavor of your roast will be very dependent on the consistency of the grind, so you want to make sure that you find a grinder that is going to offer different features.
There is the blade coffee grinder which is the most popular type, and also the most expensive. These grinders consist of a simple motorized fan-like blade that spins in a plastic casing. You have most likely seen one of these grinders or something like them before, and although they are completely simple, usually with nothing more than an on and off button in terms of features, they also work the best.
The only real disadvantage to these coffee grinders is that they tend to grind the beans inconsistently.
There is also the option of getting a burr coffee grinder, which is one that works by crushing the coffee beans between one spinning and one stationary disk. These disks spin slower than those in the blade coffee grinders, which is important because it means that they will deliver a more consistent grinding of the beans, and therefore a good tasting roast.
There are more disadvantages to the burr coffee grinders than their blade counterparts however, which is why they are, for the most part, less popular. More than anything, a downfall to these coffee grinders is that they have to be cleaned on a regular basis. You will probably even have to clean after each grind, and it requires a fair bit of work.
You also have to keep in mind that the beans which are fed from a hopper, can get stuck from time to time and so you will need to stir them to get them moving and flowing into the disks again.
