What's the difference between American coffee and hand-brewed coffee? Must American coffee be worse than hand-brewed coffee?

If you want to have a cup of black coffee in the shop, would you choose a cup of hand-made coffee or American coffee? Most of the time people prefer to make coffee by hand. So what's the difference between American coffee and hand-brewed coffee?

First of all, American coffee and hand coffee get a cup of black coffee (black coffee). The difference between American coffee and hand-brewed coffee lies in the way of extraction. American coffee is made by pressurized extraction of espresso liquid from an Italian espresso machine and mixed with the corresponding water.

The hand brewing coffee is a simple trickle filter extraction, without pressure, the unit extraction efficiency of the hand brewing form is much lower than that of the Italian coffee machine, so it is necessary to correspondingly extend the extraction time and need more water to achieve the total extraction rate.

In theory, the extraction efficiency of the Italian coffee machine can not only make coffee a few blocks away, but also extract coffee substances that cannot be extracted from hand-brewed coffee (substances with both good and negative flavors). That being the case, why is the flavor of hand-brewed coffee still varied, while American coffee is generally single?

The answer lies in beans, because many stores use espresso not only American coffee, but also a variety of milk coffee, which makes the selection of beans to meet a variety of espresso derivatives requirements (compromise).

If we put aside the question of cost to test the difference between American style and hand-made coffee beans, the first thing to do is to unify coffee beans, this test will use a medium-shallow roasted beans and medium-deep roasted beans for comparison.

The first is medium-shallow roasting, using the Ethiopian Sakuran 4.0 of Qianjie Coffee.

The brewing parameter of hand-brewed coffee is 20g coffee powder, the ratio of powder to water is 1:15, that is, the amount of water is 300g. The water temperature is 91 ℃ and the degree of grinding is medium-fine grinding of hand-brewed coffee (the pass rate of standard sieve 20 is 78%). The cooking method uses the front street three-stage water injection. The actual coffee solution is 260g. The extraction time is 2 minutes.

The parameters of American coffee are as follows: after many times of grinding, the parameters of espresso are 20g coffee powder to extract 40g coffee solution for 30 seconds. Add 220g water to 40g coffee liquid to unify the standard of powder quantity.

Compared with the two, on the aroma level, the aroma of American coffee (berries, flowers). In terms of flavor, there is little difference between the two, and the sweetness of hand-made coffee is slightly better. In terms of hierarchy, hand-brewed coffee is more abundant and American coffee is monotonous. In taste, hand-brewed coffee is fuller, while American coffee is slightly thinner.

The next step is to compare the medium and deep baking, choosing the Brazilian Queen Manor Huang Bourbon, which is the coffee in the front street.

The brewing parameter of hand-brewed coffee is 20g coffee powder, the ratio of powder to water is 1:15, that is, the amount of water is 300g. The water temperature is 89 ℃ and the degree of grinding is fine grinding of hand-brewed coffee (the pass rate of No. 20 standard sieve is 67%). The cooking method uses the front street three-stage water injection. The actual coffee solution is 260g. The extraction time is 2 minutes.

The parameters of American coffee are as follows: after many times of grinding, the parameters of espresso are 20g coffee powder to extract 40g coffee solution for 28 seconds. Add 220g water to 40g coffee liquid to unify the standard of powder quantity.

Compared with the two, on the aroma level, there is little difference between them (peanuts, nuts). In terms of flavor, American style is sweeter. In terms of hierarchy, hand-made coffee is more abundant. American coffee is more full-bodied and mellow in taste.

By comparison between the two, handmade coffee performs better in medium and shallow roasting, while American coffee is more pleasing in medium and deep roasting. However, there is one drawback in American coffee, that is, hand-brewed coffee performs better than American coffee in terms of hierarchical change.
