For many, grinding one's own coffee is an intimate part of the coffee making experience, as well as one more way to control the final outcome of the coffee. The best way to keep the aroma of your coffee intact is to grind it just before use. As coffee interacts with air, it loses flavor and aroma, even with the hour, and the longer your ground coffee sits out, the less aroma your cup of coffee will have when made. Controlling the size of the grind will also have a big impact on your coffee. The wrong grind in your coffee maker can not only ruin the cup of coffee, it can also harm your coffee maker by clogging it. The right grind will be determined first, by your equipment, and then by the way your coffee is roasted, as well as how fresh it is.

Types of Coffee Grinders
There are two main types of coffee grinders: burr grinders and blade
grinder. You can then divide burr grinders into conical grinders and disk
burr grinders and then again to low speed and high speed. Conical burr
grinders are designed with two ridged and cone-shaped burrs that grind and crush
the coffee beans. Standard disk burr grinders have to rings that are
parallel and serrated on the sides that face each other. In each of the
burr grinder styles, one burr stays stationary while the other is turned by the
motor and the coffee beans are pulled between the two and crushed.
Low Speed Burr Grinders and High Speed Burr Grinders
Low speed burr grinders are considered to be the best and
are designed with two ridge and cone-shaped burrs that grind/crush coffee
beans. They are capable of preserving the most aroma and can achieve
an especially fine grind with good consistency. The burrs are
designed with a high gear reduction and generally stay below 500 rpm,
which gives them the capacity to grind finely but at a very slow
speed. This is very important because it means less heat. Heat
during grinding can be extremely damaging, as it ruins both the aroma and
can also scorch the coffee, giving it a bitter/burnt flavor. Conical
burr grinders are able to cover a wide range of grinds and are therefore
suited for almost any equipment, including: Drip Coffee Makers, French
Press, Percolators and Espresso Machines. High quality conical burr
grinders are also easily capable of achieving a grind fine enough for
Turkish coffee. They also have the upper hand in coffee grinding by
produce little to no static charge, are very quiet to operate and don't
clog easily when grinding especially fine grinds.
High speed burr grinders give an even wider range in grind size, but are not
quite as preferred as low speed since they can more easily over-heat the
coffee beans if attempting to grind large amounts at one time. For small
amounts, this will likely never be a problem. They are also slightly
louder and produce more static. However, they are also more affordable
than low speed burr grinders, and for anyone seeking a basic coffee grinder to
perform well on a daily basis with small quantities of beans, they are more than
capable of meeting basic grinding needs very well.
Blade Coffee Grinders
Blade coffee grinders operate at a very high speed,
usually between 20,000 and 30,000 rpm. This means a hotter
environment for coffee beans and more opportunity for coffee dust, a
problem for coffee makers like pump espresso machines that have mesh metal
baskets that can be easily clogged. They are also harmful for
espresso machines with sieves in and for French presses, but are primarily
designed for drip coffee makers. Another downside to blade coffee
grinders is the static charge that the coffee grounds will likely pick up
during this type of grind, which can be messy and hard to clean up.
You determine the size of the coffee grounds by the length of time you
allow the grinder to run. The longer the blades are run to chop
coffee beans, the finer the results. The positives to blade coffee
grinders include a decreased cost, as well as their ability to last longer
than burr grinders.
Making the Decision
If you're seeking an enhanced coffee-making experience with the opportunity
to control the size of your coffee grind, as well as the chance to preserve the
aroma of your coffee, than a grinder is certainly an addition you should
consider. If expense is not a determining factor, then a low speed conical
burr grinder is most likely your best option. You can achieve any range
needed, and you'll maintain all the aroma. If the cost is a big influence,
take a look at what might be your next best option. We offer plenty of
models in every type that will get the job done for you, whatever your
particular needs might be!
