With regard to the thickness of coffee powder, many people have a misunderstanding, thinking that the finer the coffee powder is, the better coffee can be made and the more mellow and tasty it will be. This is wrong. So what is the right size of coffee powder?

1. Choose the degree of grinding suitable for coffee utensils.

"the finer the grinding degree is, the stronger the bitter taste is, and the thicker the ground bean is, the weaker the bitter taste is", which is the basic law in the process of coffee extraction, which is caused by the difference of the surface area of coffee powder covered by hot water. from this we can know the relationship between coffee utensils and the grinding degree of coffee powder. If you use an espresso machine, you must finely grind the deeply roasted beans and use the espresso machine to extract a small amount of coffee liquid in a short time to get a strong espresso. What happens when the same coffee powder is extracted by trickling filter (American coffee machine, or filter paper hand flushing)? If you do it, you can see that the filter paper will be blocked by coffee powder, making it difficult for the injected hot water to pass, and the extraction time will be lengthened, resulting in excessive extraction and unparalleled bitterness.

2. Will the coffee powder with ultra-coarse grind be better?

Each coffee utensil has its own suitable degree of grinding, so we don't use whatever degree of grinding we want. As mentioned above, the drip filter method of making coffee (American coffee machine, or filter paper hand-brewing), coffee powder is too coarse or too fine, that is to say, it is most suitable for medium to medium roughness. If it is too fine, the coffee powder will block the fine holes of the filter paper, and if it is too thick, it will allow hot water to pass through the filter paper easily, and the delicious ingredients of coffee will not be fully extracted. In this way, the coffee from the coffee pot becomes a light, thin liquid.

3. The relationship between the degree of grinding of coffee powder and the extraction method.

1) suitable for fineness grinding: Turkish copper pot, mocha pot, Italian coffee maker, Airou pressure. 2) suitable for medium grinding: American coffee machine, filter paper hand dripping filter method, ear filter paper, filter paper smart cup, flannel dripping method, method pressure. 3) suitable for medium roughness grinding: plug air kettle (also known as siphon pot). 3) suitable for roughness grinding: Vietnam drip filter pot, stainless steel filter smart cup.

4. Why do Italian coffee machines use deep-roasted coffee beans to make coffee?

After deep roasting, coffee beans release more coffee oils, which are of great significance for espresso, because espresso is generally used to make lattes, cappuccinos, etc., and to make such coffee, espresso is needed as a base, which requires a high degree of mellow and thick to blend perfectly with soaked milk. Only deeply roasted coffee beans, and then fine grinding, can extract such an espresso base. In addition, deep roasting will make the coffee beans soft and easy to grind. Although this is a bit superfluous, some Italian-made bean grinders cannot crush lightly roasted hard coffee beans. The grinder is originally designed for deep-roasted coffee beans, which can break down immediately when used to grind light-roasted coffee beans with hard texture. It seems that the performance of the bean grinder also represents the personality of the country.

Which coffee tastes better, espresso machine or filter paper hand-brewed coffee? The espresso machine is mainly used to make espresso, which is mainly used to make lattes, cappuccinos and so on. This espresso liquid will taste strong, but can not reflect the flavor of the place of origin. In general, it is difficult to reflect the flavor of the coffee itself after deep roasting. On the other hand, the filter paper can make a cup of coffee with native flavor, which is rich in taste, suitable for drinking directly or mixed with fresh milk, and is more convenient.
