There are many factors that affect the taste of coffee, including its preparation method and usage temperature, but the freshness of coffee beans is the most important.
Most coffee beans are sold in UV resistant vacuum containers, but once opened, the flavor begins to lose its original flavor over time.
Especially for ground coffee beans, the storage time is shorter, so grinding coffee beans before making coffee is better than grinding them in advance or buying coffee powder.
And you also need to control the grinding size, which is a key point for those who like to use coffee press or cold brew coffee.
Why is it necessary to use a coffee grinder?
If you grind coffee beans at home, you must use a coffee grinder. reason:
1. Food processors, mini shredders, and mixers used for grinding coffee beans are unreliable.
Although blade grinders are similar to food processing machines and mini shredders, their edges are easily blunt and cannot achieve the effect and flavor of coffee powder ground by coffee grinders.
2.When coffee beans are ground, they release oil stains that often leave marks in the container, which can smell like coffee no matter how many times you clean a food processor, mini chopper, or blender.
Which type of coffee grinder is the best?
There are two main methods for grinding coffee: you can use a blade grinder or a burr grinder.
Blade grinder:
The working method is similar to a food processing machine with blunt edges, where the blades rotate to chop coffee beans.
When the beans are intact, there will be a loud sound during the startup process, but when the beans are broken, the startup process will be relatively quiet.
Overall, blade grinders are smaller and more compact than burr grinders, but they struggle to produce coffee grounds of uniform size.
Burr grinder:
The working principle is similar to pepper grinding, where coffee beans pass through two metal or plastic objects and are then ground into pieces.
The grinding size can be precisely controlled according to the settings of the grinder, and the results are very uniform, which helps to obtain a fuller and more balanced taste.
It is larger than a blade grinder, produces louder sound during operation, and is usually more expensive.
Manual grinder:
It works similarly to pepper grinding and requires multiple rotations of the handle to the coffee beans.
Manual grinding machines are small in size and cheap in price, with low noise, but the perfect setup is not easy, and the grinding time is longer than what we spend.
When grinding coffee, it is important to grind the coffee powder more evenly to achieve maximum flavor during the brewing process. Uneven grinding of coffee may lead to the final flavor of the coffee.
Moreover, different coffee brewing methods require different sizes of coffee grounds and brewing times. Coarse coffee grounds require longer soaking times compared to finer ones, and vice versa.
