Espresso knowledge learning, why coffee powder should be compacted?
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.
