How to choose coffee grinder is a very important question to ask. You must break coffee beans into small pieces so as to increase the surface area so that you can extract more flavors and aroma as well as other ingredients from the beans.
The finer the size of your grounds the faster it will be to extract the good stuff from the coffee beans. Grinding the beans to the right size for your brewing method is also very important.
It is recommended that you only grind coffee beans right before you brew. This allows for a better tasting cup of coffee.
Grounds that are allowed to sit undergo oxidation which causes the grounds to become stale and dramatically decreases the taste of the final coffee.
Types of Grinders to Choose From
The first you should know when considering a coffee grinder is that there are two types of grinders – these are blade and burr grinders.
Blade grinders are the more affordable types of grinders and they often are the most straightforward and most common available. These coffee grinders can be found from a wide variety of retailers both online and offline.
These grinders have a blade and a motor and vessel into which you pour your beans. They are easily operated by the press of a button and grind beans by the rotation of the blades which break the coffee beans into pieces.
A longer grind time allows for a finer grind. The overall process of grinding with a blade grinder is very easy but there is the drawback that you don’t have a lot of control over the uniformity of the grind and so you may have some parts of your grounds that are chunky and other parts that may be powdery.
Under this category there are two subtypes. You can find a flat blade burr grinder and a conical burr grinder. Burr grinders are the most highly recommended grinders.
The flat blade burr grinder features two burrs that are parallel to each other. These burrs are flat and break up the coffee beans with a shearing effect.
The conical burr grinder has two burrs that are cone shaped that face each other. One of these burs remains stationary while the other one rotates to crush the coffee beans against each other.
You will find further classifications of burr grinders such as by dosing capability, speed and the available types of grind adjustments.
When it comes to speed you can find gear reduction low speed models, direct-drive high speed models and direct-drive low speed grinders. Your entry level models most likely will have a high speed direct drive motor that is attached to the burrs directly.
These models will add heat which in turn will lower the quality of the grounds. These also tend to be a bit noisy and produce static that can cause lumps in your grounds.
Then there are the gear reduction low speed models and the direct drive low speed models. These are often the types of grinders you will find in commercial coffee shops.
You will find that coffee enthusiasts will have these in their homes. These grinders will offer little to no static so you don’t have to worry about your grounds clumping up.
They are also a lot quieter than high speed directed drive models and don’t produce heat to reduce the quality of the final taste of your cup of coffee. The direct drive low speed grinder is probably the pricier version when looking at coffee grinders. A reduction low speed model will be a bit noisier than a direct drive slow speed model.
When you are looking at how to choose coffee grinder you want to look at just more than the price. Remember that the quality of your grounds affect the taste of your final cup of coffee and so you want to start with a good quality coffee grinder.
The best types of grinders to purchase are burr grinders as these allow for more control over the grind size and also allow for more uniform grounds. If you are looking to create a tastier cup of coffee you don’t want to skimp on quality and purchase an inferior coffee grinder, do the right thing and choose the best coffee grinder that you can afford.
