Is it important for semi-automatic coffee machine to press powder?-how to use semi-automatic coffee machine brand recommendation
Notes on using a semi-automatic coffee machine to make coffee:
1. Coffee powder should be carefully ground.
2. Choose the right amount of powder according to the coffee machine.
3, pressing powder, (it is recommended to buy a pressing powder stick) be sure to press, flatten, and then knock off the loose powder.
4, brewing time, espresso generally in 20-30 seconds, when the outflow of coffee obviously thinning and whitening, it can be closed.
5. Observe the situation of crema (coffee fat). A good espresso will have a layer of reddish brown foam floating on the coffee surface. Adjust the grinding degree, powder quantity, time and so on of the next coffee powder according to its condition, which depends on experience.
6. Before making, you need to turn on the machine and let it warm up for a period of time. The preheating time varies according to the machine. Please refer to the instruction manual.
7. Warm the cup. Please heat the coffee cup before making any coffee.
8. Do not touch the outlet directly with your hand after production. It is still very hot after natural cooling for 2 hours.
Press the coffee powder in the strainer forcefully and evenly.
The powder press (a tool used to press the coffee powder in the filter) should touch the coffee powder vertically in the front. If there is a certain bevel when pressing, the surface of the coffee powder will be uneven.
Press the coffee powder four times in the order of "east, south, west and north" in the filter basket. Only in this way can the coffee powder be pressed evenly and the water pass through a uniform piece of coffee pressed powder.
If the pressure is not too tight, the espresso brewed is like water, lacking flavor and low alcohol. Moreover, due to excessive extraction, there will be a bitter taste.
After pressing the coffee powder evenly to form a smooth surface, you can put the filter in the espresso machine and begin to brew.

To judge whether the pressing strength is appropriate, you only need to observe the state of the used wet coffee powder, which determines the quality of coffee extraction. If a "wormhole" appears on a damp coffee pressed powder, it means the water has found an easier way through.
seven
After the used wet coffee powder is poured out of the filter, it should be in the shape of a small hockey ball. If they are mushy, there is a problem with the grinding and / or powder pressing process.
eight
The key lies in practice. Only by practicing constantly can we master a better powder pressing technique.
