Why does espresso taste better with a coffee machine?

The coffee machine has made greater changes in the coffee brewing process, making the coffee taste more mellow and delicious.

Before the birth of coffee, coffee from roasting, to grinding, and then to cooking, although the details will vary from region to region, but the general brewing method is the same. However, since the invention of the coffee machine, a variety of coffee machines have changed the brewing process of coffee, and the taste of coffee has been more evolved, so that more mellow and delicious coffee was born in the world.

After the coffee is ground into powder or fine particles, if the water temperature is too high, the oil in the coffee will evaporate quickly, and this oil volatilization will make the coffee lose its unique mellow flavor, and the taste will only become very bitter. In order to retain this mellow aroma, the water temperature provided by the coffee machine can not be too high, and the emergence of electronic devices can achieve the subtle regulation of temperature, which can meet the needs of brewing all kinds of coffee with different temperatures.

In addition to the fact that temperature affects the aroma of coffee, brewing time is also a key factor. The oil in coffee is easy to volatilize at higher temperatures, the more it volatilizes over time, and the volatilization is very rapid. Therefore, if the coffee can be brewed in a faster time (coffee powder and hot water are perfectly mixed), the mellow aroma of the coffee can be better preserved. And the best way to make coffee brew faster is to let the coffee machine pressurize the water. Increasing the pressure in the water container can make the hot water have a faster speed at the moment of outflow, achieve the rapid brewing of coffee and better retain the oil in the coffee, so that people can enjoy its mellow aroma. In this way, the brewing time of coffee can be as low as 25 seconds.

The advent of coffee machines has not only given birth to more coffee flavors, but also accelerated the brewing time of coffee, but there are still many people who do not like this quick way of brewing coffee, thinking that it is not as emotional as traditional coffee brewing. Lost the enjoyment of slowly tasting coffee. But it is undeniable that the coffee maker does retain the mellow aroma of coffee.
