Basic knowledge of brewing coffee can coffee be "brewed"?
If we define "boiling" as heating water to 100 degrees and keeping it at that temperature for a long time, then coffee cannot be brewed. Because the source of flavor in coffee (aromatic oil) will be destroyed in the process of "boiling" at high temperature for a long time. Therefore, about 92 degrees Celsius is the ideal temperature for coffee extraction. So whether you are soaking (French pressure pot), or using a coffee machine, or siphon pot and other appliances, the water temperature of extracted coffee can not be higher than 96 degrees Celsius. So coffee can't be brewed in this sense.
In this way, in the production of filtered coffee, we can clearly see that the coffee should be brewed instead of being boiled like porridge. We use a variety of heat sources to heat only the water used to extract coffee, rather than directly boiling the mixture of boiling water and coffee powder (Turkish coffee is outside the scope of this discussion).
