The differences among the six types of powder presses find a suitable powder press and do a good job of each cup of Italian concentration.

Powder pressing hammer is one of the most commonly used tools in espresso. The main purpose is to flatten and tamp the coffee powder in the handle to form a flat horizontal plane, to better let the hot water be extracted through the coffee powder, and to make the coffee powder withstand the great pressure caused by the coffee machine extraction. without being washed away and impressing the quality of the extraction. The force of the pressing powder should be determined according to the grinding thickness of the coffee powder, and the reference basis is the flow rate of coffee during extraction (extraction time 25 ±3 seconds). If the flow rate is too fast, the powder pressing strength is too light; if the flow rate is too slow, the powder pressure is too heavy, which will directly affect the Italian concentrated product and the taste of the coffee. In addition, everyone's application strength will be different, and there is a great difference between boys and girls, so it is necessary to adjust the corresponding strength according to the actual extraction effect.

The classification of powder press is mainly divided into six categories:

1.C-Ripple: improved on the basis of Ripple, the pink hammer is made into a flat bottom at the edge, with multiple raised concentric circles in the center, and the pressed powder center is wavy and the edge is horizontal.

2.Ripple: it's hard to control. The bottom of the powder hammer is wavy.

3.C-Flat: it belongs to the combination of Euro Curve and Flat. It doesn't have a curved bottom like Euro, but like Euro, the pink hammer has a height difference, the bottom has a horizontal flat bottom, but the edges are curved, and there is a height difference.

4.Flat: the most common powder press with a flat bottom at the bottom.

5.Euro Curve: the bottom of the powder hammer is arc-shaped, and the highest height difference at the edge of the powder hammer is in 3.355MM.

6.American Curve: relative to the bottom Radian of the Euro Curve, the height difference between the highest point of the arc and the edge of the powder hammer is reduced to 1.661MM.

All right, let's stop here. In fact, if you want to be a good barista, you must have your own special powder hammer, which can ensure that you have a feel and the tamping strength tends to be perfect!
