Video course on correct techniques of Coffee cloth Powder-Coffee embossing
Cloth powder is the process of putting the ground coffee powder into a powder bowl and distributing it evenly. The successful distribution standard of coffee powder is to make coffee powder evenly distributed, so that some areas will not be overextracted or underextracted during extraction.
When you put the coffee powder into the powder bowl, the powder will be piled like a hill in the middle, usually more in the middle and less around. In the extraction, due to the inertia of the water, the flow of water will be easier to pass through the middle, so in theory, the amount of powder in the middle of the powder bowl should be more than four weeks.
However, because the powder bowl structure of the double-headed handle is different from that of the single-headed handle, we need to treat it differently.
Water will flow out of these pits, and there is no doubt that this place has become a route for the rapid flow of water, resulting in uneven extraction in this area, and of course the aroma of coffee is out of the question.
Now let's talk about the impact of too tight pressure on Espresso extraction. If the coffee powder is pressed very tightly and the water cannot penetrate the pressed powder at nine atmospheric pressures, I dare not imagine the taste of this cup after dripping 30ml and the time it will take. I believe such an espresso would also be a very failed cup.
Tell your friends how the correct coffee powder filling is done. In the process of pressing the powder, after evenly laying the coffee powder, the action of pressing is carried out immediately. Generally, there is an action of leveling with a slight force, and only after this action is the action of real pressure. At the end of the mild pressure, some people will have a bump on the handle to let the powder attached to the powder bowl fall into the powder bowl, and then put the handle hammer horizontally in the powder bowl and rotate clockwise three times. Then rotate counterclockwise once and lift the handle hammer so that our coffee powder is pressed.
The above mentioned rotary pressing powder is to make the coffee cake surface smooth, beginners often can not grasp the strength but the coffee cake pressure is uneven, so we can try to reduce the pressure as much as possible. try this method when you have a good grasp of the pressure.
