Why a Good Coffee Grinder is Important?

Many real espresso coffee experts believe that using a good grinder is the essential first step in making a great shot of coffee. Your espresso machine is nothing without the services of a grinder - one that is capable of grinding those magic beans finely enough for the espresso machine to extract the sweet flavors of the coffee.

So it's important to know what features you should look for? How much will you use it and where will it sit - one thing is for sure, you probably don't want a massive commercial grinder sitting on your kitchen bench. How much are you prepared to spend? Many variables and decisions need to be made based on your individual needs.

The good news is that there is certainly a wide range of grinders suitable for the domestic market - some are compact and specifically designed for home use, while others are for commercial purposes. You cannot avoid the fact that a good quality grinder is one of the essential pieces of equipment in the entire process. So, before you buy a mazzer Espresso grinder, you need to consider some factors.

Key factors you need to consider are:

Temperature stability - grinding coffee beans in itself generates heat. The grinder blades must not overheat [as a result of the mechanical friction of the blades, the conductive heating of housing materials, or the working of the motor], as this can further expose the coffee to heat. Remember that roasted coffee is a delicate, perishable product, and overheating may affect the flavor, along with potentially swelling the bean, affecting the fineness of the grind for a given setting [and therefore affecting the extraction]

Burr grinders vs blade grinders - one of the keys to espresso coffee is being able to grind finely enough to create resistance to the water being pushed through the coffee to extract the oils and hence the flavors. Blade [or spice] grinders, having a chopping mechanism, cannot grind the coffee beans finely enough to do this. Secondly, the chopping method does not produce a good consistency of the grind. Having some particles much coarser than others leads to an inferior espresso result.
