What is American coffee?

American coffee is a kind of Italian coffee, usually choose medium to deep roasted coffee beans, through the pressure of the Italian coffee machine to let the hot water through the ground coffee powder, extract Espresso. Normally, a cup of American coffee is made from one or two servings of Espresso and diluted with hot water. American coffee is based on Espresso,Espresso "espresso", which originated in Italy and is mostly extracted from espresso by an Italian coffee machine.

After being made into American style, there is an obvious improvement in sweetness, and the flavor will be more balanced, but the taste is thin, the flavor is monotonous and the level is insufficient.

The common painful experience of all coffee beginners is that they do not know the objective criteria of coffee, including the flavor of beans, how fine they should be ground, how to cook them, and how long it takes to cook them. The Italian coffee machine provides a very precise standard, the traditional definition, the use of 9 atmospheric pressure, extraction time 25 seconds, brewing 30cc coffee, through the above standards, we can go back to determine the amount of beans, grinding thickness and filling pressure channel to achieve a standard extraction.

As the brewing of the Italian coffee machine will magnify and highlight the characteristics of the coffee flavor, we use the standardized brewing of the Italian coffee machine to find out the original flavor of the coffee (although it will be relatively strong), which can be used as a reference for the adjustment of the flavor and methods of other brewing methods. This is the inspiration given to me by the Italian coffee machine. In addition, in addition to the number of seconds, espresso can be used to determine whether the extraction is complete or not, and the cup can be opened immediately when the color of the outflow becomes lighter, which is also one of the advantages.
