Last Updated: 2025/08/21, Coffee is a violent thing. Coffee is taken from its friendly home, in bags or jars, and put into bean hoppers, which in itself is not a bad place. But when the grinder is turned on, as soon as the coffee begins to grind into small particles, you immediately hear the sound of the motor and the sound of the burr spinning wildly. This is where the action takes place and where your coffee experience begins.

Grinding coffee is a very violent thing. Coffee is taken out of its friendly home, put in a bag or jar and put into a bean bucket, which in itself is not a bad place. But when the grinder is turned on, and when the coffee begins to grind into small particles, you will immediately hear the sound of the motor and the crazy whirling of the burr. This is where the action takes place and the beginning of your coffee experience. So how on earth does the bean grinder affect coffee?

The final result of espresso / coffee will depend on the uniformity of coffee grinding and the final temperature after grinding. Yes, that's right. When coffee is ground, it absorbs calories, and the more calories it absorbs, the greater the impact on the final product. If you only grind enough coffee, the coffee will not absorb too many calories from any grinder. As the grinding cutter head and surrounding parts get hotter, the more coffee you grind, the hotter it will be.

Another possible by-product of ground coffee may be a terrible static charge, which can cause ground coffee to jump out of the ground coffee container. You have to see it to believe it. Have you noticed that your hair stands on end when you put on a sweater? No, it's not a ghost, it's static electricity.

When the coffee is ground and then forced to enter the container through a chute, a static charge is formed. The factors affecting this electrostatic phenomenon are the speed of grinding burr, the way coffee passes through the chute, humidity, temperature and coffee itself. Most of these factors are difficult to control, but it is easy to control the grinder you buy. In general, the grinder that produces the most electrostatic charge and adds the most calories to freshly ground coffee is the high-speed grinder.

Grinding size

What we are talking about is how fine or thick your coffee is ground. The size of the grinding you need is directly related to the type of equipment used to brew the coffee, the freshness of the coffee, and the way it is roasted. Different types of espresso / coffee machines are designed to extract flavor and aroma from coffee in different ways. Therefore, they need to be ground in different sizes. The following will provide guidelines to help you understand the conditions you need to make the most of an espresso / coffee maker.
