Generally speaking, there is no pre-soaking in American coffee machine! And what is prepreg?

The purpose of pre-soaking is to hope that the coffee powder will wait for a period of time before it is fully soaked by water, and during this period, the hot water will be poured into the coffee powder, and in the moistening process, the coffee powder will be heated and will continue to release CO2 gas, so that it can accept the baptism of hot water and fully extract flavor substances.

Hand flushing, will first put some hot water on the coffee powder, wait for a period of time, and then start to inject water! Different factions, some will wait for 30 seconds, some will wait for the coffee powder to lose its luster!? Or the surface falls at the same time, followed by water, and some people use a section of water injection method, but at the beginning, the current is relatively slow. All these ways show that prepreg is necessary!

The advantage of the American coffee machine is that it is plugged in! When water injection, water cut off, water injection, can be controlled by the switch, therefore, if you want to make the American coffee machine have greater benefits, it is recommended that you start using the method of pre-immersion! Two-stage water injection: turn on, start the first water injection, the amount of water is about the same as the volume of coffee powder, turn it off, (patiently) wait for 30 seconds, turn it on, until the cooking is complete, turn it off.

Want to add flavor? This trick must not be saved!

If you are a heavy user of hand flushing, I believe you must know the importance of prepreg, which is a necessary means to help extract; and the use of water cut-off method is an alternative method to increase flavor, generally speaking, two-time water cut-off method and three-time water cut-off method are the ways that more people are trying!

You can also move this way to the American coffee machine! What is meant by water cut off? Is to turn off the power! How many times do you want to break it? Just a few times! Of course, not for fun, but to increase the flavor!

How long will it take to turn it on? It is suggested that if you can, observe the water in the filter cup of your American coffee, the water has all seeped down, it is the time to refill it! If you can't see it?! Just use the second-reading method, about 10-15 seconds, which is probably enough, why only catch 10-15 seconds? Because it is afraid that the coffee powder will become cold, and at that time, it will not be conducive to extraction, so it will take 10 to 15 seconds.

It is suggested that this method can be used to compare "fresh" beans, such as beans that have just been baked for one to three days, or beans that are more "lightly baked".

Of course, the water cut off is to increase the "good" flavor, if the American coffee machine after the water cut off found that the flavor does not increase, of course, it can be omitted ~ generally speaking: sweetness will increase! However, if the astringency increases, it means that the water is cut off too often! Or there is no need to cut off the water at all!
