Last Updated: 2024/06/13, Speaking of Japanese coffee, I believe that in addition to the extremely deep-roasted coffee beans with dark and shiny appearance, the soft and elegant water injection method is also the impression that everyone will associate with Japanese coffee. Indeed, most of the water injection methods we use to make coffee by hand today are rapid and "rough", because in this way we can get a cup of water in the shortest possible time.

Speaking of Japanese coffee, I believe that in addition to the dark and dark roasted coffee beans, the soft and elegant way of filling water is also the impression of Japanese coffee that everyone will think of. Indeed, nowadays, most of the ways of injecting hand-brewed coffee are fast and "rough", because only in this way can we get a rich cup of hand-brewed coffee in the shortest time. Therefore, the slow injection of Japanese cooking is in sharp contrast to it, which will look more elegant and exquisite. Therefore, today Qianjie would like to share some of the most classic brewing methods in Japanese coffee.

Kono style cooking Kono drip method originated in 1973. As its name suggests, it was invented by the Kono family, which founded Kono, a well-known Japanese coffee maker. The Kono family liked deep roasted coffee so much that they took the brewing effect of flannel filter cloth as a reference template to design and invent the Kono filter cup. Then, in order to make the brewed coffee more mellow and refined, the drip method has been developed, which shows their deep love for mellow and deep-roasted coffee.

The reason why this cooking method is called drip method is largely due to the fact that in the cooking process, the first stage of water injection is not the usual injection of hot water, but continuous, well-grained water droplets continue to drip. This action can prolong the steaming time during brewing, so that the carbon dioxide in the coffee is fully released, so that the subsequent hot water can better extract the flavor substances from the coffee. When the filter paper is completely soaked by the coffee liquid (or the coffee liquid filtered by the filter cup has changed from drip to water), it means that the steaming has been completed, and we can change the way of water injection and quickly extract the aromatic substances from the coffee through a large flow of water.

It can be said that pine house brewing is a unique representative of Japanese brewing, because it has three extremely striking characteristics: ultra-long steaming time, high water injection height, and ultra-strong coffee liquid that needs to be diluted with water.

The purpose of steaming for a long time is to make coffee beans with different freshness have the same extraction efficiency; to inject water at an ultra-high position is to make the injected hot water have a precise temperature without a thermometer. The super-concentrated coffee liquid is because under the ultra-high extraction efficiency, the flavor substances can be extracted without too much hot water, so a pot of high concentration coffee liquid can be obtained by raising the ratio of powder to liquid, and finally diluted to your favorite taste through bypass.

Volcanic cooking is the most ornamental of the three ways. Because this way will make the coffee powder bed in the brewing process of continuous air, forming a volcanic eruption of the general scene, very spectacular!

Similarly, volcanic flushing also requires muggy exhaust before extraction of flavor substances. But the difference is that the hot water injected during the flavor extraction stage is not injected in one breath, but is divided into several segments, each time the water is injected in a small circle in the middle of the filter cup, a small amount of light injection, and then injected into the next section at an interval of 5 seconds. until the target water is injected. In this process, we can see that the powder bed expands because of the injection of hot water, shrinks because of the penetration of coffee liquid, and then the hot water is injected, re-expanded, re-permeated, re-contracted, and repeated. Because of the high extraction efficiency, the ratio of powder to liquid it uses is also relatively high, so the final extracted coffee liquid will also be a high concentration that needs to be diluted by bypass.

But either of the above brewing methods will be more suitable for deep-roasted coffee beans, because they are all developed around how to extract mellow deep-roasted coffee. If you also like calm and mellow bitter coffee, you might as well try these Japanese brewing methods. I believe that you will get a unique experience when this is different from the usual way of brewing.
