There are not many tools used to make coffee by hand, and filter cups, hand pots, sharing pots, filter papers, electronic scales, thermometers and so on are all indispensable, each of which may affect the flavor of coffee. If you fail to brew a cup of coffee because of a certain link, I believe you are also very annoyed.
Today let's talk about filter cups. Filter cup is the carrier of coffee production, there are different materials, each material has different characteristics, then you may ask which material is easy to use, the following will introduce you to the material of coffee filter cup!
In addition to the styling design, there are also many differences in the material of the filter cup.
Common filter cup materials include: ceramic, glass, resin and metal. In theory, the heat conduction speed of different materials will be different, but because the hand punching time is short, only 2-3 minutes, so the filter cup material actually has little effect on the temperature difference.
1. Ceramic 2, Ceramic 3, Resin 4, Glass 5, stainless Steel 6, Copper
No matter what the material is, it is recommended that the filter cup should be washed with hot water before use, on the one hand, to clean and disinfect, on the other hand, it can reduce the temperature difference between the filter cup and coffee liquid, and prevent the water temperature from falling too fast in the extraction process. In the brewing technique, you only need to pay attention to the filter cup with few holes and brew it slowly with a small amount of water column, so that the water will not be silted up.
Most of the filter cups are made of plastic, transparent glass, ceramic, stainless steel and red copper. the material of the filter cup directly affects the temperature of hand punching.
First of all, in terms of thermal conductivity (W / m °K):
Red copper (401) > stainless steel (122.45) > ceramic (1.22) > glass (1.1) > plastic (< 1)
The higher the thermal conductivity, the more the material can take the heat away, so it is more necessary to warm the cup before hand flushing, otherwise the water temperature drops more obviously during cooking. From this point of view, plastic is a good choice.
Here are the advantages of each material finishing--
Plastic: no need for warm cup, high precision metal: more durable, high temperature resistant ceramic: good heat preservation effect, high temperature resistant glass: good light transmittance can observe the flow condition.
Usage of kono filter cup
When using this filter cup, it is recommended not to soak the filter paper beforehand. the purpose of this is that because of the short ribs, if the filter paper is wet before cooking, the upper cup wall will be closely attached to the filter paper, affecting the exhaust of the steaming process. So it is best to match KONO bleached filter paper, try to use weak paper filter paper, so that without wetting the filter paper, the stew exhaust of coffee powder will be better with the lower rib space.
After the normal stewing, when the water level has not passed the ribs and the upper filter paper has been attached to the filter cup, it is time for this filter cup to witness a miracle. When the air flow above has been blocked, a confined space is created below, and the air can only flow downwards, so that both the water and the air have to pass through such a unique passageway, thus creating a relatively strong downward pulling force.
The lower opening of this generation has been reduced to make the extraction force more concentrated, and the water can give the coffee powder more time to soak, avoiding the fact that the water just brews the surface of the coffee powder, creating a miscellaneous flavor and astringency.
So you will find that the use of KONO filter cup will have a feature, that is, the downward flow is relatively concentrated and uninterrupted, forming a uniform flow of thick top and fine bottom. There is another key point to use the KONO filter cup, that is, to break the siphon effect at the right time, that is, if you inject water again when the downward extraction effect is almost over, it will break. At the same time, according to the extraction mode of the tail section, the filter cup should be removed at the right time.
The most important feature of KONO filter cup is that the coffee liquid is very thick and full of flavor, which has the flavor of typical Japanese hand flushing.
The usefulness of a small filter cup can be so great, and the performance of different materials is even more different. do you think the water in the coffee world is also very deep? In fact, these are not casually produced, but after countless improvements to the final production, because of the dedication to coffee, faith in order to make a small filter cup representative ah!
