When did the origin and development of American coffee flow into China?

The name of American coffee comes from the habit of American soldiers in Europe during the war to mix hot water into small portions of espresso that are common in Europe. It is said that the Apollo spaceship, which landed on the moon for the first time, had a life-and-death failure on its way home. At that time, the ground crew comforted the three astronauts with a word: come on! Delicious hot American coffee is waiting for your return.

Because Americans generally make coffee casually and simply, this method quickly became popular with the popularity of American chain stores in the world. Normally, a cup of American coffee is made by blending two espresso espressos with 30% 470ml hot water. Because of the large amount of hot water added, American coffee will look light both in appearance and in taste. In addition, the aroma of coffee will be slightly damaged as a result, and can not last as long as traditional espresso. Despite the addition of hot water dilution, American coffee still contains more caffeine than regular coffee. But its calories are very low.

In the United States, Australia and New Zealand, the practice of blending with hot water and then espresso is sometimes called Long Black. Sometimes, some simple coffee machines are also called American coffee machines. Actually, they are drip coffee machines.

But in today's coffee market, such as coffee shops in Australia, it is common. They say that if the coffee is overextracted, wouldn't it take longer for the autoclave and siphon kettle to extract than that? So what's wrong with doing this?

Let's not compare the differences in taste between the two methods, because differences arise when it comes to this aspect. But it should be known that the caffeine content in light coffee extracted for a long time will be higher than that made by diluting a standard cup of Espresso with water. Even so, there are two ways to make coffee: Espresso diluted with water and then Espresso with water. At that time, most Americans used the filter method to make coffee with a lighter flavor. To this day, most Americans use drip coffee pots in their families, which is why they are also called American coffee pots. But the popularity of American coffee made by diluting a cup of Espresso with water is due to the global opening of Starbucks stores.

So is it the right way to make a cup of mild coffee from the Italian machine for a long time? There are two opinions. Traditional Espresso advocates don't think so, because coffee is overextracted, especially in the later stage of extraction, which removes the miscellaneous flavor and excessive caffeine of coffee powder, and these people despise this method.
