Selection of beans and grinding for dripping coffee machine-value of grinding fineness of coffee machine

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 coffee powder is too coarse or too fine to make coffee, that is to say, the most suitable grinding degree is medium to medium roughness.

The following is the relationship between the grinding degree of coffee powder and the extraction method:

1. Suitable for fineness grinding: Turkish copper pot, mocha pot, espresso machine.

2. Suitable for medium grinding: filter paper dripping filter, flannel dripping, plug air kettle (also known as siphon kettle).

3. Suitable for roughness grinding: dripping coffee machine, dripping filter pot. TIPS: by the way, the Turkish copper pot, shaped like a spoon, is filled with coffee powder, water and sugar and boiled over the fire. This method of extracting coffee, known as "boiling", uses a deeply roasted, finely powdered coffee powder. Why use deep-baked coffee powder? The astringent taste of light-roasted and moderately roasted coffee powder will be enhanced after boiling at high temperature, while using deep-roasted coffee, even if extracted at high temperature, the coffee is completely bitter.

Why do espresso machines use deep-roasted beans to make coffee?

There is another reason why espresso and Turkish coffee use deep-roasted coffee. Because deep roasting will make coffee beans soft and easy to grind a little finer. 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.
