Italian style is too strong, or like American smooth, to my taste, so in the end is American filter coffee or American coffee in the Italian system is better? Can the coffee beans used in the American coffee machine be used in Italian coffee? This paper gives the following thoughts

Assuming the same bag of American coffee beans, the same water quality, the same extraction rate, and the same concentration, then the difference between the two is mainly the difference in temperature, pressure and filter.

●, let's start with filter

Italian coffee machine powder bowl is a pinhole, will maximize the extraction of oil, alcohol thickness, thick feeling will be better than the American coffee machine.

There are two kinds of American coffee machine, one is filter paper, the other is metal mesh. Filter paper is characterized by filtering out most of the grease and caffeine, reducing the weight, but bringing cleanliness. Although the metal mesh grease is more than the filter paper, but the pressure is much lower than the Italian machine, so the oil can not catch up with the Italian extraction.

●, besides the temperature.

Italian machine temperature is adjustable, very constant, generally set between 92 and 96, once set, it will be quite stable (Italian coffee machine with independent temperature control system for the brewing head), other low-end mechanisms create problems, which will lead to the temperature instability of the extraction head, which is another topic.

American coffee machine, I measured one, the temperature is not constant, from 82 to 92 degrees after extraction, the flavor level of the non-constant temperature system will be better than the constant temperature system, and the body and sweetness of the constant temperature system will be better. And American trickling filtration is easily affected by room temperature.

● finally said that the pressure

Italian extraction usually has a pressure of nine atmospheres, which will extract flavors and oils in a short time.

American trickling filtration can only use the local air pressure, but the extraction time is prolonged, and the extraction rate can be comparable. The biggest difference brought by the pressure is the oil.

The difference of ● powder bowl / filter cup

This leads to the difference of extraction efficiency, but it is assumed that the extraction rate is consistent at the beginning. However, according to Matt Perger's concept of uniform extraction, the uniformity of powder bowls is better than that of American trickling cones and baskets. That is, the sweet feeling of the powder bowl is further enhanced.

● to sum up, assuming that the conditions are the same as an American coffee bean, the same atmospheric pressure, the same room temperature, the same water, the same extraction rate and similar concentration, then the results will have the following differences:

The American coffee from the Italian extraction system is round, mellow and sweet.

The American coffee produced by the American trickling system is layered, clean, slightly flat and slightly astringent.

Of course, the above also assumes that you can do the correct extraction of Italian.

The effect of baking degree on the two systems has not been investigated here, and can be further discussed if you are interested.

These differences are impossible for people who are insensitive to their senses. If they are interested in fine taste, they can stick to them. After all, they add a lot of fun, so why not--
