What filter cup can be called a coffee smart cup? What are the characteristics of the Infinite Cross Filter Cup? Newbie coffee filter cup recommended

Although there are many kinds of filter cups on the market, few filter cups can be associated with a certain way of cooking. Few does not mean no, such as infinite filter cup, it can be said to have a deep binding relationship with one-throw cooking. Because of this, whenever Qianjie shares a throwing style of cooking, there will always be friends in the backstage private message Qianjie: it's time to stir-fry the cold rice with unlimited filter cup.

The strange-looking filter cup above is the infinite filter cup, which was launched by Hario, a well-known Japanese coffee maker, in 2021. Yes, it is the Hario that produces the king of performance-to-price ratio V60! In terms of appearance, there is not much difference between the infinite filter cup and the V60, it is a tapered filter cup with an angle of 60 degrees, but the design of the inside of the cup wall is slightly different. But it is precisely because of the different inside design that the infinite filter cup has a completely opposite extraction effect with the V60!

The most important feature of V60 filter cup is its fast launching speed. Compared with other filter cups, the launching speed of V60 filter cup can be said to be dustproof. Not only because it has 12 protruding diversion ribs, but also because it has a large bottom hole, while the infinite filter cup is just the opposite, its flow rate can be said to be the slowest of all filter cups. The main reason is that the infinite filter cup has no protruding ribs.

The ribs exist not only to guide the flow of water, but also to separate parts of the filter paper from the filter cup, creating many channels through which the gas can flow. If a filter cup does not have protruding ribs, this will make the filter paper closely adhere to the filter cup, resulting in an air lock effect that reduces the flow rate of coffee liquid. The so-called gas lock effect refers to the phenomenon that the gas gathers and hinders the normal flow of the liquid in the process of liquid flow. Fresh coffee is rich in gas, and when we brew coffee, the gas in the coffee powder will be released by the contact of hot water. If there is no dedicated channel for the flow of gas, then the gas will accumulate in the powder bed and then occupy the flow channel of the liquid, resulting in a decrease in the flow rate of coffee liquid. Therefore, most filter cups are equipped with protruding ribs to prevent the infiltration time of the liquid from being greatly extended.

On the other hand, the infinite filter cup goes in the opposite direction, and the inside of the cup wall is specially designed without ribs, in order to prolong the extraction time of coffee, so that hot water can be accumulated in the filter cup, thus forming immersion extraction. Not only that, the immersion type of infinite filter cup is different from that of other filter cups, because its flow rate is so slow! How slow is it? It is about 1/4 of the flow rate of V60 filter cup and about 1/2 of that of kono filter cup. Such a slow flow rate will leave the coffee in the whole process of soaking extraction, but because there is no valve at the bottom to block the flow of water, we can understand that it is a mixture of trickling and soaking extraction. Because of this, the infinite filter cup has aliases such as "Smart Cup version of filter Cup" and "lazy filter Cup" on the Internet.

But strictly speaking, the filter paper will not completely fit with the infinite filter cup. Although there are no protruding diversion ribs on the inside of the wall of the infinite filter cup, there is a concave exhaust channel designed. Although these channels can not play the role of diversion, but can let a small amount of gas out of the channel, so as not to block the water. Another factor causing the slow flow rate of the filter cup is that its bottom hole, whose diameter is in 1.5cm, is the same size as the V30 shared in Qianjie yesterday. Due to the extremely slow flow rate, this filter cup is very suitable for one-throw cooking. When the official launched this filter cup, it was suggested that it should be used with a throw-in type of cooking. Because of this, the one-throw type is bundled with the infinite filter cup! When it comes to one-throw cooking, people think of the infinite filter cup, and vice versa, it is not too much to say that it is a tailor-made filter cup.

Then in front of the street to share, infinite filter cup with what kind of parameters, and how to cook it!

Infinite filter cup brewing scheme if we want to use one-throw cooking when using an infinite filter cup, then our extraction parameters need to be extreme, because it does not form a complete immersion and the coffee liquid will flow out continuously. The beans used in the front street are Santavini, Ethiopia, and the parameters are as follows: amount of powder: 20g powder ratio: 1:15 water temperature: 95 °C grinding degree: Ek43's 8-scale grinding (90% screening rate of sieve 20). The front street has also shared in one-throw articles, one-throw cooking is very simple, just dig a hole in the filter cup, so that hot water can come into contact with the bottom coffee powder more quickly. We can inject all the hot water in one breath. So when everything is ready, we just need to inject all the 300ml hot water.

At the same time of injection, it is best to circle continuously, which can effectively increase the extraction rate of coffee. In 45 seconds, the front street will finish injecting the total amount of 300ml hot water, and then you just need to wait for the coffee liquid to be filtered, and then you can remove the filter cup and finish the extraction.

It took a total of 3 minutes and 20 seconds, and the coffee liquid ran out. It can be seen that the powder pit exposed is deep and uniform, which is as perfect as the fit of its filter paper, which can make people with obsessive-compulsive disorder ecstatic. And the coffee is also very good, not only has an outstanding flavor performance, but also a high sense of sweetness, although it tastes a bit like coffee from a smart cup, but the level will be relatively richer. So much for the sharing of brewing. It is worth mentioning that the infinite filter cup and its cup holder are not integrated and can be detached. So we can often see some witty friends take it out, install it with the valve of V60 Smart Cup, and assemble it into a real "Infinite Smart Cup" with high playability. Interested friends can also give it a try, but if it's broken, you can't rely on Qianjie.
