The definitions of the two concepts have different starting points. Black coffee refers to the taste. All coffee without milk, sugar and anything is called black coffee. American coffee refers to the practice of coffee, including hand-made, pressure pot, siphon pot and American coffee machine. These are all American coffees.

Actually, black coffee is easier to understand. I hope that black liquid is too bitter for many people to swallow. But I like drinking coffee, and I have to make a cup of single product by myself every morning. Then a cup of single product, sugar-free and milk-free, is called black coffee.

In this way, my black coffee is hand-brewed American coffee. Every time I use a bean grinder to grind coffee beans into powder, then I put the filter paper into a funnel and slowly pour it out with the water in the coffee pot. In fact, when I am used to drinking black coffee, I really feel that its taste is distinct, sometimes it smells like flowers, sometimes it smells like citrus, and sometimes it is a little sweet and sour.

In fact, when the Germans invented the American drip coffee machine, they also suffered from the residue of coffee powder, so they thought that housewives had fantastic ideas. Anyway, great inventions are waiting to be awakened by Apple. German housewife Ben Ci Meletta is a Virgo. The housewife is very upset about the coffee residue left between her teeth and thinks about how to solve it. Then one day, she made a hole in the bottom of the copper bowl, somehow put her son's blotting paper on it, separated the coffee powder and rushed into the hot water. Suddenly, coffee dripped into the pot through the paper. Perfect, the coffee grounds disappeared, so her method was preserved.

But why did the things invented by the Germans end up called American coffee? No way, because the final automatic filter was successfully developed in the United States, otherwise how can we say that the United States is powerful? In fact, if we put aside all kinds of hand washing methods, the automatic drip coffee machine is really the most convenient means to obtain black coffee, and the price is not expensive.

Although American coffee is simple, it is still very important. For example,

Americano's practice is to add Espresso to water, extract espresso first, and then add hot water, that is, dilute espresso with water.

Another method, LongBlack, is just the opposite of Americano. First add hot water, then pour the espresso into the cup and let it spread naturally.

According to online comments, the two tastes different, and the long black will have a more layered feeling, because espresso is slower and softer.
