Guidelines for using hollowed-out wire filter cups for hand-brewed coffee can you make hand-brewed coffee without a filter cup?

Hand coffee cannot be made without a filter cup, which can not only support the filter paper, but also help us to extract better coffee flavor substances. However, let's try a filter cup made of iron wire in front of the street today!

Let's first look at the characteristics of this "filter cup".

This "filter cup" can clearly see that it is made of a wire, and the wire incisions at both ends can be clearly seen.

Stretching the wire or extruding the wire can still restore the original state.

Because it is made of a wire, the four brackets at the bottom are not actually on the same horizontal line, so the frame on the sharing pot will not be flat and will tilt to one side.

Let's try to make coffee.

First put on the filter paper and wet it with water.

Qianjie observed that most of the filter paper would be affixed to the filter cup, but the top iron ring did not fully fit. But in fact, it will not have much impact.

This time we use coffee beans from the Red Cherry Project of Yega Schiffy on the front street, and pour in 15g coffee powder.

At the beginning of water injection, first inject 30g water for steaming for 30s, the overall performance of the powder layer is not much different from that of using V60 filter cup. But this filter cup is so crooked that it will kill obsessive-compulsive disorder. AHA!

Then continue to inject 120ml water into segments, and finally finish the injection to 225ml.

The time to wait for the coffee liquid to flow out is 2 minutes and 40 seconds. In the case of the same parameters, the extraction time required to use the V60 filter cup is 1 minute 50 seconds. In other words, the diversion of this "wire filter cup" can not be said to be very poor, can only be said to be none at all. The role of the wire frame is only one to support the shaping of the filter paper.

Generally speaking

The coffee flavor from this "filter cup" will be thick and sweet. Since there is no reverse flow, the whole extraction is only affected by gravity. This will be more demanding for water injection, and your uneven water injection will certainly lead to uneven extraction of coffee.

However, this is very convenient, can be compressed into a sheet, easy to carry out and use, other properties do not need to be compared with other filter cups.
