Italian concentrated Grinding degree Evaluation how to make Coffee scale

The friction heat of ① is suppressed to a minimum. (the aroma will fly away because of the fever)

Whether the size of ② particles is uniform or not. (if the particles are uneven, the concentration will be uneven.)

Taking this as a consideration, if you are a household mill, you should rotate it gently and take care to avoid friction heat as much as possible. Therefore, it is more appropriate to use electric grinders.

How to use the mill

Grind the beans before brewing.

There are two types of household mills: manual and electric. The manual type is used if the number is small, while the electric type is more convenient for the large number of people.

Determine the grinding method (particle size) with the bubbling apparatus.

Manual grinders should be careful not to produce friction heat only. And pay attention to whether it is mixed with other things.

Whether the granules of ground coffee beans are large and neat or not should be checked. (in the case of uneven particles, it is possible that the function of the grinder is always, or coffee roasting is not symmetrical, etc.)

Because the texture and origin of coffee are different, coffee beans must be ground finely if you use a semi-automatic coffee machine. Before you grind coffee, take a moment to take a closer look at the coffee beans, particle size, smell fragrance, different regions of coffee, such as African coffee, Brazilian coffee, Southeast Asian coffee are different, this depends on experience, it's a long story. In addition, the time and thickness of grinding coffee depends on the aroma and taste of the coffee itself, rough grinding or fine grinding of coffee, depending on the method you use to brew coffee. In general, coffee that is finely ground and faster takes less time to brew. This is why coffee is made in a coffee machine, and everyone chooses carefully ground coffee, which is based on the fact that the drip irrigation system of the coffee machine is suitable for brewing.

Humidity factors play a role not only in sunny and rainy days, but also at different times of the day. Generally speaking, the humidity in the morning and evening is higher than that at noon, so according to the influence of humidity factors, the grinding degree should be thickened in the morning and evening, and finer at noon.

There are many other factors that affect the degree of grinding, including the roasting degree of coffee beans (although coffee beans used by Espresso should use a deeper roasting degree, but sometimes different roasting degrees may be used to roast formula beans for richer taste), blended recipes, and so on. All of the above are the most common and can be mastered by baristas. The previous sections are all about the adjustment of the basic factors in the production process in order to meet that taste standard on the premise of understanding the good taste of Espresso (see the taste of Espresso). There are many places in the world of Espresso that we don't fully understand, and we would like to explore this wonderful world of coffee with you.
