Would you like to add water first or ​ after making American coffee? Does the order of American coffee and water affect the taste?

In a recent conversation with a guest who arrived at the store, he talked about American coffee. He said: "the most authentic way of American coffee is to take out espresso first and then add water. Now it's all about pouring coffee into the water."

In fact, this is also the question that many enthusiasts like to discuss before, "whether American coffee is to add coffee and then water, or to add water first and then coffee". We know that American coffee is a simple "espresso + water", but there will be some differences in the order in which it is added. First add espresso to the cup, and then add water, the impact of water will wash away the Crema on the surface of espresso, so there is only a thin layer of light white foam on the surface of espresso. If you first add water to the cup, and then add espresso, the surface of the American coffee will be floating with a rich layer of golden Crema. On the other hand, there is almost no difference in taste and taste. Of course, if you distinguish the difference between the two by the degree of nitpicking, that is, the American style with water and then coffee will drink more strongly at first, because the aroma and bitterness of Crema floating on the surface are more obvious than coffee liquid, and the coffee liquid permeates slowly downward, which tends to be strong and weak. And first add coffee and then water, under the impact of water, the concentration of the whole cup of coffee will be more uniform. However, the difference in the order of coffee and water is not as great as the difference in taste when espresso is extracted for 2 seconds more (or less). The earliest practice of American coffee is to extract espresso from the cup and then add hot water to dilute it. The reason for doing this is because of the production habit, the espresso machine is usually filled with coffee cups, on the one hand, to preheat the coffee cup, on the other hand, to hold it easily. When making espresso, baristas often pick up the coffee cup and place it under the coffee shunt after buckling the handle. Make espresso before adding milk or water to the coffee cup.

It is not new to pour water into a coffee cup and then extract espresso. This practice is popular in Australia and, of course, they will call it Long Black. (the difference between American style and Long Black is not the order of coffee and water, but the ratio of coffee to water. For more information, please click here.)

Later, with the emergence of special small cups for concentration, the order of water and concentration for making American coffee will not be too particular, basically how to save time and how to do it. However, because the practice of adding water before pouring espresso can make the liquid surface retain a wealth of Crema, compared with no Crema, the former looks better and the visual impression will be improved a lot. Therefore, there is more practice of water before coffee now.

Therefore, American coffee can be filled with water first or later. There is no such thing as an authentic sequential approach.
