Salvadoran coffee bean flavor secondary roasted coffee

At the end of steaming, the coffee beans will quickly change from white to light brown, and the coffee beans will continue to absorb heat to reach an explosion, and the coffee beans will expand from steaming to shrink and dehydrate, and the moisture content of the coffee beans will decrease rapidly. when the heat absorption reaches the extreme point of the coffee itself, there will be an explosive reaction, which is called an explosion. 3, the stage of one explosion (before the end of the first explosion): 15-18 minutes after the beginning of the explosion, the coffee bean will begin to give back the "just right heat" you gave it, showing a perfect exothermic reaction, and then we can obviously smell that the aroma of coffee will change from the smell of grass to coffee coke, and with the progress of the explosion, the coffee beans will burst and expand? From now on until the coffee is charred, basically all the coffee can be drunk, and there will be no taste of grass, but the coffee at the beginning of the explosion will be very sour and not bitter. With the passage of time, the taste of coffee will turn into non-sour and extremely bitter. Generally speaking, the bean point will be determined by the flavor of the coffee itself. When the sour taste is fast and the bitter taste is about to appear, this is usually the bean spot in the mother's mouth.

After the first burst, the coffee bean will slowly mature and emit a charming aroma, and when the heat absorption reaches the second peak again, the coffee bean will have a second explosion, that is, the so-called second explosion, which will open a space in the heart of the epidermis, and the carbon dioxide in the coffee bean will continue to be discharged, causing the internal temperature to rise continuously, start coking, turn into oil, and ooze out of the coffee surface. At this time, the coffee flavor will be bitter, strong flavor, usually Starbucks is baked to this stage, and then continue, the coffee beans will slowly turn into coke, except bitterness without any flavor?
