How to grind coffee beans correctly? Under normal conditions, the coarseness of coffee will be related to the extraction time and extraction rate.
How to grind coffee beans correctly
The degree of grinding should be proportional to the extraction time. The roughness of coffee grinding will directly affect the extraction time and extraction rate. The finer the coffee is ground, the denser the powder layer is, the more coffee powder particles are in contact with hot water, the greater the extraction resistance, the easier it is to prolong the extraction time and improve the extraction rate, and it is easy to over-extract. On the contrary, the coarser the coffee is, the larger the gap in the powder layer is, the less coffee powder particles are in contact with hot water, and the weaker the extraction resistance is, the more difficult it is to prolong the extraction time, and reduce the extraction rate, which is easy to be insufficient. Therefore, the finer the coffee is ground, the longer the extraction time and the higher the extraction rate; the thicker the coffee is, the shorter the extraction time is and lower the extraction rate. Under normal conditions, the fineness of coffee is inversely proportional to the extraction time and extraction rate. The coarser the powder is, the smaller the extraction resistance is, the greater the coffee flow is, the shorter the extraction time is, the lower the extraction rate is, and the lighter the taste is.

The common method of brewing and extraction of coffee? Is leaching an ideal household method for brewing coffee?
How to extract coffee: the easiest way to brew coffee is to put the coffee powder in the cup and add hot water. As it cools, the coffee powder will sink to the bottom of the cup. This is an old method, and it is still used in some parts of Indonesia. Be careful not to eat the coffee at the bottom of the cup. The advantage of this method is that it is simple and the water temperature is just right. Pressurized espresso is made from 80 to 96 degrees Celsius.

How to use the grinder to help coffee extraction uniformity Coarse coffee particles are more easily extracted, while finer particles will be extracted in advance, so the larger the grinding thickness span of coffee powder, the more you can taste more turbid, stimulating miscellaneous taste. However, when coffee powder with the same grinding particle size and relatively similar shape is extracted, the taste becomes brighter and brighter.
