The number on the engraving plate of the bean grinder represents the grinding coefficient. The smaller the number is, the finer the ground coffee powder is, and the larger the number is, the thicker the ground coffee powder is. Different coffee beans and coffee utensils should also use different thickness. Although each item has a rough grinding range, but there is no absolute value, players can find out the most suitable grinding degree through testing. Generally speaking, the roughness and fineness of coffee bean grinding can be divided into rough grinding, medium grinding and fine grinding. The coffee machine and brewing method are also different.

How bitter is the coffee? So sour?

Everyone wants to drink good coffee, sweet and palatable, with explosive aroma and long aftertaste, and hope to drink this kind of coffee every time.

There are many factors that affect the taste of coffee: time, temperature, brewing equipment, etc., but the most important key to good coffee is the thickness of grinding besides good beans and good equipment.

The right thickness makes more delicious coffee.

The secret of good coffee lies in extraction, but what exactly does extraction mean? Extraction is the process in which the flavor and aroma substances of coffee beans are released into water and combined with water, resulting in a cup of delicious coffee.

However, these flavors and aromatic substances represent a certain flavor, some bring sweetness, some are bitter, some bring fruit flavor, and some bring astringency. These substances will also be extracted at different points in time.

The order of substances extracted from coffee is as follows:

Sour, sweet, bitter, and finally astringent.

This means that while controlling the extraction rate, you can control how much substance will dissolve into the coffee, in other words, you can determine the flavor of the coffee. Whether you brew or brew espresso by hand, this is the basic rule for creating a brewing formula.

And the thickness of grinding is also one of the considerations.
