Last Updated: 2024/11/03, Seeing this problem a few days ago, I felt that it was necessary to popularize the knowledge of grinding, pressing and applying powder. The reason for compacting the coffee powder is that when using an Italian coffee machine, the hot water brewed has about 9 atmospheric pressure, which is very stressful. When the water penetrates the coffee cake, the water is inert. What is inertia, that is, water will come from the weakest of coffee cakes

Seeing this problem a few days ago, I felt that it was necessary to popularize the knowledge of grinding, pressing and applying powder. The reason for compacting the coffee powder is that when using an Italian coffee machine, the hot water brewed has about 9 atmospheric pressure, which is very stressful. When the water penetrates the coffee cake, the water is inert. What is inertia, that is, water will penetrate through the weakest part of the coffee cake, not from the thickest place. Therefore, if it is not compacted and flattened, the essence of coffee will not be extracted, or some parts will be over-extracted.
