What are the characteristics of the ice pupil filter cup? How do you make coffee by hand?
At the beginning, people may pay more attention to the extraction effect of hand filter cup and experience the difference of coffee brewed by different styles of filter cup. With the increase of brewing times, we gradually understand the underlying logic of each filter cup and different extraction methods, and the selection of filter cups has changed from their own "talent" to "appearance". Hey! Hey! Which one looks good, buy / use which one!
Therefore, our protagonist today is the "Ice pupil filter Cup", which was sought after to a certain extent because of its good appearance when it was launched.
It doesn't work (onomatopoeia), it sparkles! Ice pupil filter cup is also a kind of conical filter cup, but its wall is different from other conical filter cups of the same type! In daily life, our commonly used conical filter cup will have a prominent diversion bone. These protruding guide bones can form an exhaust groove between the filter paper and the cup wall, and it is well known that the length of the exhaust groove can determine the speed of flow. The reason why the exhaust trough is mentioned here is that the exhaust groove of the ice pupil filter cup is not built with prominent guide bones, but is a groove directly from the inside of the cup to the outside of the cup.
Come on, give the camera to its side! From this direction, we can directly see that its cup wall design is divided into three parts: the first part is the smooth surface at the top, which does not have any groove design and can fit perfectly with the filter paper; the second part is located in the middle of the filter cup, composed of 24 finer grooves; the third part is located in the lower layer of the filter cup, which is composed of 12 thicker grooves, extending to the outlet.
Each thick concave groove in the lower layer will be arranged in the shape of inverted A formed by the two thin grooves above. It can be said that the lower layer is almost like Origami, in an overhead state. This kind of design can stagger the flow rate of water in different positions, and the 24 fine grooves in the middle layer will slow down the flow of water and increase the time of immersion and extraction, until the flow reaches the lower groove, the overhead design will speed up the flow of water, so as to avoid the occurrence of over-extraction!
Therefore, the ice pupil filter cup also belongs to a faster flow rate of a filter cup. So, what is the difference between it and the coffee extracted from our commonly used V60 filter cup?
In the experiment, the filter cup with faster flow rate will be more suitable for cooking shallow and medium-baked beans, so today we compare the beans used to decide that it is "Jade Manor Green Rose Summer" ~ absolutely not because of public gain in front of the street. That's what you say when you want to drink (probably)! Use bean quantity: 15g grinding scale: Ek43 10 scale powder water ratio: 1:15 (225ml) boiling water temperature: 92 °C cooking method: three-stage first stage, we use twice the amount of powder 30ml for 30 seconds of steaming, and then slowly around the big circle, into the second stage of 120ml hot water, when the water level is about to see the bottom into the remaining 75ml hot water, slowly around a small circle, until the drip is finished!
The extraction time of V60 is 2 minutes and 15 seconds, and the green standard with it has the sweetness of melon, soft citrus acid, jasmine aroma and obvious green tea feeling! The extraction time of ice pupil is 2 minutes and 16 seconds, which is almost the same as that of V60. The green label it rushes out also has the aroma of jasmine, the sweetness of melon, with a hint of orange peel, the taste will be thicker than V60, and the sense of tea is slightly weaker. The advantage of V60 is that the extraction time can be controlled by the flow rate of water injection, the taste will be brighter, cleaner, and the layers will be richer, but it will lack mellow feeling. The advantage of the ice pupil is that the middle and upper layers of the filter cup can form immersion extraction, the brewed coffee will have a fuller experience and the alcohol thickness will be higher. But its hierarchical sense is not as obvious as that of V60, and its aroma and acidity become somewhat general.
In addition to the appearance of the ice pupil filter cup, there is also an attractive advantage! That is, it can easily allow the filter paper to fit the filter cup, and it does not have to take as much trouble as other tapered filter cups to achieve a certain degree of fit! This is not too good for obsessive-compulsive disorder and patients!

According to the Southern Metropolis Daily, on December 1, the Central Court of intellectual property Rights and International Trade of Thailand announced a verdict on the trial of Luckin Coffee Company of China against Royal Thailand 5.
Why is the extraction time of hand-brewed coffee and Italian coffee so important?
When many Xiaobai friends first come into contact with coffee, they will pay great attention to grinding, powder water ratio, water temperature, techniques and other controllable things related to production, only "time", this uncontrollable factor is easy to be ignored by everyone, but in fact, it is very important for the production of a good cup of coffee.
