“Absolutely delicious!”In the beginning of his previous video, Mr. Tetsu Kasutani introduced to everyone the coffee brewed using his improved hybrid brewing method.(Please call me a screenshot geek)Front Street believes that everyone should no longer be unfamiliar with Tetsu Megu. He is not only the champion of the 2016 World Coffee Brewing Championship, but also the inventor of the well-known brewing methods "Four-Six Brewing" and "Hybrid/Demon Brewing Method".Whether it is "four or six flushes" or "mixed flushes", it is all a matter of philosophy.It was developed around the concept that "anyone can make delicious coffee". Therefore, these brewing methods are very simple to operate. Even a novice can easily brew a cup of delicious coffee.As mentioned before, Mr. Tetsu Kasutani has recently improved the mixed brewing method. Although the changes are only two small actions during the brewing process, the stability and uniformity during brewing have been greatly improved, making it easier to brew delicious coffee. So today Front Street is going to share something about this new boat(brand new)This version of mixed brewing, what kind of brewing method is it~What is mixed brewing? In fact, it is easy to understand. It is a brewing method that combines different extraction methods. The different extraction methods here actually refer to "soaking" and "drip filtering."The so-called soaking is a method of extraction by soaking coffee in water; the so-called drip filter is another method of extraction by washing the coffee with water. The mixed brewing method means that during the brewing process, there is both immersion extraction and drip extraction. This is a relatively rare practice in coffee production. But because this method requires the coffee powder to be soaked in water for a period of time, it needs to be used with a smart cup with a valve.Since the mixed brewing method is a brewing method derived from the four-six method, the theory of the two is the same, and the only difference lies in the actual operation.As the name suggests, the four-six-flush method splits the total water injection amount into the first 40% and the last 60% injection. The amount of water injected in the front part is 40% of the total water volume, which determines the flavor of the coffee(The balance between sour and sweet); The amount of water injected in the latter part is 60% of the total water volume, which determines the taste of the coffee.
The mixed brewing method also divides the hot water used for brewing into the first 40% and the last 60%. The principle is the same, but the difference is that it does not have so many water injection stages, and immersion extraction is added during the brewing process.There are five stages of four-six flushing. The total amount of water injected in the first two stages is 40%, and the total amount of water injected in the last three stages is 60%. The mixed brewing methodThe first two sections are the same, both are drip filter extraction. The difference is that the last three stages will be concentrated into one stage of injection, which is also 60% of the total water volume, but the extraction method used is soaking instead of trickling. The specific operation is very simple, just close the valve of the smart cup before filling it with water and then fill it with water.But because it is combined with immersion extraction, the soaking time is relatively long. Therefore, in order to prevent bad substances from being dissolved, the water temperature in the third section will be lowered.The improved version of the mixed brewing rule is based on the original one, changing the first stage of steaming from drip filtering to immersion, and splitting 60% of the latter part into two stages of injection, one for drip filtering and the other for soaking. The purpose of this change is to allow the coffee powder to fully contact the water during the steaming stage to fully exhaust, and then the subsequent extraction can be more uniform and stable.That’s a rough introduction to the operation. Next, Front Street will demonstrate how to brew this new version of the mixed brewing method~How to brew the new mixed brewing method?This time, Front Street will use Front Street Jade Manor·Diamond Hill from the Front Street Bean List for demonstration. The brewing parameters are as follows:Use filter cup: Hario V60 smart cupAmount of powder used: 20gPink to water ratio: 1:15Grinding degree: Fine sugar grinding, Ek43 10 scale (No. 20 sieve pass rate 75%)Brewing water temperature: 92°C for the first three sections and 70°C for the last sectionFirst, we close the valve of the smart cup, then inject 2 times the amount of water as the powder and steam for 40 seconds.(The purpose is to make the exhaust more sufficient)。After steaming, we open the valve and release the coffee liquid in the filter cup. When the coffee drip filter is completed, use a small flow of water to inject the second section of hot water in a circle from the center outward. The amount of water that needs to be injected in this section is 80ml, that is, the electronic scale displays 120ml, and the water injection time can be controlled within the range of 20 to 30 seconds.When the coffee dripping in the cup is almost filtered, the valve remains open and we inject the third stage of hot water. Similarly, use a small water flow to inject in a circle. The amount of water injected in this section is 80ml, that is, the electronic scale displays 200ml.While waiting for the coffee to filter, we add a certain amount of room temperature water to the kettle to cool the hot water to a range of 70°C~80°C.At about 2 minutes and 10 seconds, the coffee liquid in the smart cup is finished dripping. At this time, we can close the valve and then inject the remaining 100ml of hot water in one breath for 35 seconds of soaking.When the time reaches 2 minutes and 45 seconds, we can open the valve to end the soaking, and then wait for all the coffee liquid to drip out before removing the filter cup and completing the extraction!The total time is 3 minutes and 20 seconds. Although it is much slower than the conventional brewing time, because we lowered the water temperature and used more immersion extraction, the coffee does not taste over-extracted and is actually very delicious. The flavors of citrus, berries, and apricots are well displayed. The taste is balanced, the sweetness is higher, the taste is as smooth and mellow as honey, and the finish is like oolong tea, which is very long.So the above is the operation process of the new version of the mixed brewing method, you can refer to it. But as Mr. Tetsu Kasutani said in the video, this operation process can be used as a template for reference, and everyone can change it at will, because everyone's taste preferences, utensils, and beans are different. As long as you understand the general principles and operations, and then customize the operation according to your own understanding, the coffee brewed will definitely taste more in line with your preferences, and this is the concept that Front Street has always shared with everyone~
