The correct method of filling Italian Coffee Powder Press Coffee Powder

I want to explain first.

There are a lot of things I don't want to explain.

It's about coffee brewing, not just about one aspect of the operation.

Because a lot of things are connected.

Especially the sensory part.

For example, I may think that there is something wrong with what some people do.

But I don't want to mention it.

Because I didn't get their coffee.

I'm not qualified to talk about it.

Remember: coffee is for drinking, not for watching.

Therefore, I would like to talk about some techniques here, whether it is Italian style, hand cooking or other brewing methods.

I seldom talk about my own methods.

It is also because maybe some people see my sharing and cook it in my way.

But I didn't see anything else I did.

Especially in PTT, there are restrictions on textual narration

As a result, rushing out is not to his liking (it is not necessarily that the cooking is wrong, it may be his own sensory problems)

Just say: Xiao Dou teaches really badly.

That's not what I meant.

I try to express myself clearly in words.

But if you really can't understand it, I really suggest finding a good teacher to take it with you.

Okay

Let's talk about packing.

We are making espresso (to remind you, this is the definition of SCAA, SCAE, not IES).

It is important to note that

1. Is the powder falling evenly?

two。 Is the cloth powder smooth?

The purpose of the above two items is to make the powder in the filter cup evenly distributed and there are no voids on the surface before filling and pressing.

In this way, the filling pressure will not cause uneven density and form a channel.

So, when I beat the powder with a dispenser after grinding the beans, the hand filter cup will move back and forth, left and right.

Let the powder fall evenly in the filter cup, try not to have more places and less places.

In case of this, we have to pat the filter cup to make it even.

But it has side effects. We'll talk about it later.

In the picture above, only the powder is in the middle. If you fill it directly, it is easy to produce a channel at the edge.

So when falling powder, move back and forth to the left and right, try to be uniform in the first step, and reduce the follow-up action.

If you are using a powder drop, it is OK to shake it slightly, which can flatten the powder that is not good.

Such as Berg Wu's modus operandi in WBC

However, excessive shaking is not good.

Quick tap, plus tilt

My original intention is to distribute the powder evenly, especially if there are voids on the surface.

It can be stuffed by fast tapping to make the powder roll down. in addition, it can disperse the clumps produced by static electricity.

However, if you shoot too hard, it makes the fine powder go down, which is not good.

So if you can tap quickly, if you can, you can do less.

Try to drop powder evenly in front, with less pat, so that the density of packing will not be affected.

Cloth powder, use the side of the finger to push the powder

Because the belly of the finger is convex, it is very easy to press on the powder when plucking the powder, so it becomes filling and pressing.

Some are filled and some are not, and when they are really filled with a pressurizer, the density of some areas will be different.

It is possible to use credit cards, bean spoons, or other stick-shaped things to assist with the cloth powder.

In addition, the cloth powder cannot change the uneven density that already exists in the filter cup.

It only changes the surface.

Therefore, the previous action should be accurate, and do not expect to dial back and forth to make the density uniform.

Filling and pressing, I teach beginners, but I can't teach how to feel with my fingers.

Because this will make it impossible for beginners to feel the feedback of the powder, as well as the posture of the arm and the level of the handle.

If the basic skills are well practiced, it doesn't matter how I fill it (including myself sometimes).

As long as the extraction is uniform and proper.

But if I don't practice my basic skills well, I just want to rely on some other ways.

It is often not uniform extraction.

Basic skills of filling and compaction method

1. Hold the filler handle, between the middle finger and ring finger, and hold the center of the handle in the palm of the hand.

two。 Put your hand on the packing pad, (if the average right-handed person) hold the handle in your left hand, and pay attention to see if the handle is tilted.

The handle must be kept at a level in the process of filling, otherwise the level of the filler is often noticed.

As a result, the handle is crooked.

3. The body stands in front of the bow and behind the arrow, one small step from the table

The distance is obtained by whether your upper arm can be straightened horizontally when you hold the filler in your hand and place it on the filter cup.

That is to say, the following figure is used when filling and pressing.

Shoulder, upper arm, lower arm, handle, all on the same plane

The advantage of this is

1. When you put the filler on the powder, it is easy to put it down vertically.

Because the cause is reduced.

two。 You can use the downward pressure of your body to control the filling pressure channel.

As long as the degree of body pressure is controlled every time, the pressure path will be fixed.

For example, I will ask the students to find a point on the bean grinder or coffee machine, every time the body is pressed down.

If you can see that point on the side of your head, it means that your filling pressure will reach a fixed force.

In addition, the upper arm, lower arm and palm are all applied vertically, and the packing will not be skewed because of the posture.

The palm exerts force vertically, and there is no force on the wrist, especially when filling more than 100 handfuls, the wrist is not prone to injury.

The palm of the hand can also feel the feedback of the power of the powder. As long as the powder is crooked, you will feel it immediately after getting used to it.

Finally, gently and without exerting force, let the filler turn and pick it up.
