How to use the coffee powder press?
Baristas all know that when using an espresso machine, the hot water brewed has about 9 atmospheric pressure (of course, this is not a fixed value, there are 12 atmospheric pressure or higher), and the pressure is very high, 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 you do not use a coffee powder press to compact and flatten the coffee (to make the density of the coffee powder in the powder bowl as uniform as possible), the essence of the coffee will not be extracted, or some parts will be overextracted.
