The coffee grinder – or mill as it is also known – is an important item for those who enjoy good coffee. After choosing the grain, care must be taken when establishing the correct grinding. This is because for each method of brewing requires exact granulation to extract the expected flavors and aromas.
As we mentioned here on the blog, the coffee grinder is part of the 5 M’s of espresso, which are the essential steps for brewing. But it is not only for this mode of extraction that we should pay special attention to the grinder: if this item does not have a perfect setting, such as grain size and weight, it can make the grinding very coarse resulting in a weak drink; while a very fine grind can produce strong and bitter coffee.
Basically, the longer the water stays in contact with the coffee, the thicker the granulation should be. The longer it is in contact with water, the more total elements it extracts from coffee, such as the essential oils of the bean. Also, the longer the contact with the powder, the more caffeine the final drink will have. In this other article you can better know the grinding types for each method.
Manual or electric coffee grinder: which one to choose
First, nothing better than grinding the grain at the time of preparation. The aroma and taste will be much more intense. At home, if you have a grinder, you can buy coffee beans, which is a way to preserve quality for much longer. Another option is to opt for a home espresso machine, which comes with an integrated grinder specifically tuned for this method.
The coffee grinder can be manual or electric. The manuals give a more artisanal preparation, but the electric ones are faster and grind the grain evenly. One of the advantages of the electric grinder is the definition of grain size. So you can choose between a more or less fine powder.
These simpler grinders are manual, crank operated. But for those who don’t have the time or patience to grind coffee manually, there are small and medium sized electric grinders that have a simple blade that resembles that of a blender or a blender. even more elaborate as the flat (two flat blades that grind the coffee).
With this equipment, your coffee is ground in seconds effortlessly. Just push a button. The best part is that some already come with different degrees of grinding.
These models are already larger and give greater precision to grinding. Therefore, they are used in coffee shops, bakeries and other places that sell the drink. They are ready for continuous use and require more technical knowledge to make the necessary adjustments.
Metal Blade x Ceramic Blade
One caveat here is that the metal blades perform slightly lower than the ceramic ones.
The disadvantage of the metal is that its blades do not allow cohesive grinding in relation to size. In addition, being metal, during use it heats up, which impacts the extraction of the drink. Ceramic blades, on the other hand, offer a homogeneous ground grain, essential for perfect coffee.
But metal-blade grinders turn out to be a good choice for those on a tight budget and wanting to drink fresh coffee. So you can start without fear for one of these!
