How to Choose Coffee Grinder
Most of us buy very good equipment for coffee brewing, but coffee grinder is also important for good coffee.
It is very important what kind of coffee you drink when choosing a coffee grinder. Each grinder grinds in different sizes. The shredder you use will be different for espresso and filter coffee.So make a choice based on what type of coffee you drink before you get the grinder.
Grinders with blades are the most used and affordable ones. They do the grinding process as long as you press the run button.But it is difficult to grind them in the same way each time. Especially if you grind coffee in different amounts.The advantage is that they are cheaper than other machines. Long grinding is required to obtain fine ground coffee. You can get the type of grinding you need by doing a combination of timing and attention.
Blade grinders chop instead of pulverize, they often produce an unequal grind. They cannot usually grind finely enough for espresso or Turkish coffee.
If you are looking for something a bit better quality, you should buy a burr grinder. Blade grinders spin the seeds and chop them into small pieces. The burr grinders provide a true grinding to reveal the compounds inside the coffee beans. Burr grinders can grind coffee for any intent. The wideness between the burrs into which the beans fall and are pulverized to a proper size can be varied and set up as wanted.
Specially important for espresso, because uneven grounds can cause water to canalize unequally through the coffee packed in portafilter. The heat of the beans is second critical element in keeping their flavor profile. The oils and aromas can easily squander if the beans get too hot over grinding, while most grinders will not heat the beans to a high sufficient temperature to risk this occurring. Beans must be freshly ground, because the oils and aromas deteriorate fast, normally in fifteen minutes after grinding.
The burrs are divided into conical and flat ones. Getting particles of the same size is much easier with this type of grinders.
Some of them are stepped, and the type of grinding can be adjusted. Burr grinders do not have to be expensive, they can see your work, even if it’s a manual work type. It is much better if you take the electric one if you can not take much time to do this manual grinding.
The grinding time will vary depending on the amount of coffee put in. If you grind for a very long time you will fine grind if you hold it short it will be coarse.
Conical burrs are better than flat ones, but they need replacing after you have ground around 1,650–2,000lb (750–1000kg) coffee.
Flat burrs are usually cheaper, but need replacing after you have ground around 550–1,300lb (250–600kg) of coffee.
